Siemens reinforces portfolio<br />
with process industry software<br />
Siemens is expanding its industrial portfolio<br />
by acquiring Elan Software Systems SA,<br />
based in Toulouse, France, an international<br />
software supplier for Manufacturing Execution<br />
Systems (MES) in the pharmaceutical and<br />
biotech industries. This step will enable Industry<br />
Automation, a Division of the Siemens<br />
Industry Sector, to extend its global lead in<br />
the market for industrial software. "Particularly<br />
for the pharmaceutical and biotech industries,<br />
the Elan product range ideally supplements<br />
our Simatic IT MES portfolio. Elan<br />
has excellent manufacturing process knowhow<br />
in these industries, where it has been a<br />
recognized partner and preferred software supplier<br />
to many well-known companies for<br />
twenty years. On this foundation we intend<br />
to build our worldwide MES software business<br />
in these industries", said Ralf-Michael Franke,<br />
Business Unit CEO. " We will be continuing<br />
our successful strategy. Our customers can<br />
go on counting on our outstanding range<br />
of products and services and also rely on a<br />
strong partner under the Siemens roof who<br />
can offer them security of investment ",<br />
commented Jean-Pierre Amadio, Managing<br />
Director of Elan Software Systems SA.<br />
Bronkhorst wins award<br />
for its Mass-View flowmeter<br />
Bronkhorst has won a coveted Golden Gas<br />
Award for its innovative Mass-View instrument,<br />
developed as a high tech alternative to the<br />
widely used variable area meter. The awards<br />
recognise a product’s ability to solve an important<br />
challenge to the gas industry, its<br />
technological advancement and environmental<br />
‘green’ attributes; Mass-View secured<br />
the gold award in the Mass Flow Measurement<br />
& Control section, one of only<br />
seven categories. “Mass-View was designed<br />
to mimic the straightforward features and ver-<br />
tical format of the VA meter, whilst bringing<br />
considerable operator benefits, and has made<br />
quite an impact since its launch a year ago,”<br />
says Andrew Mangell. “This Golden Gas<br />
Award means it has been recognised as an<br />
innovative and environmentally attractive product<br />
by our peers and it should encourage those<br />
who are considering a VA replacement to look<br />
seriously at Bronkhorst’s Mass-View.”<br />
Merger control authorities approve<br />
acquisition of Ciba by BASF<br />
The U.S. Federal Trade Commission (FTC)<br />
and the Chinese merger control authority MOF-<br />
COM approved the acquisition of Ciba Holding<br />
AG by BASF. No conditions were imposed<br />
beyond those required by the European<br />
Commission. Furthermore, the condition imposed<br />
by the European Commission to reach<br />
a sales agreement for Ciba's business with<br />
the light stabilizer CHIMASSORB 119 FL<br />
(HALS) before closing has been fulfilled. The<br />
buyer is the Italian company Sabo S.r.l. As a<br />
result, the conditions for the settlement of<br />
the tender offer are now fulfilled (closing): The<br />
offer price of CHF 50.00 per tendered share<br />
can be paid and the Ciba shares transferred<br />
to BASF. As of April 9th, BASF holds approximately<br />
95.8 percent of Ciba shares.<br />

A CC-Link based control system has<br />
integrated eleven boreholes in the<br />
Jutland region of Denmark, so that<br />
the on-demand water supply can<br />
cope with the increasingly variable<br />
daily demand brought about by<br />
the growth of tourist visitors.<br />
Control System Secures<br />
Jutland's Water Supply<br />
Rural West Jutland has long been a magnet<br />
for tourists, but a concerted promotional effort<br />
has built visitor number to the point<br />
where tourism is now a key part of the regional<br />
economy. However this means that the population<br />
varies considerably between the winter<br />
and summer; hence water demand can be<br />
as low as 1500m 3 per day and as high as<br />
5000m 3 .<br />
The existing supply system was based on<br />
five remote boreholes deep in the local forest<br />
and a main pumping station 1.2km way.<br />
Each borehole was 100m deep and could<br />
supply up to 30m 3 /hr. The control system,<br />
installed in the 1970s, was electromechanical<br />
and had no provision for remote monitoring<br />
so was very expensive to maintain.<br />
It was decided to sink another six boreholes<br />
and to upgrade the control system.<br />
One of the first technical issues to address<br />
was the highly distributed nature of the system,<br />
and this lead to the decision to opt<br />
for CC-Link which can be used over extended<br />
distances using either standard cabling or<br />
optical fibres.<br />
CC-Link (Control & Communication Link) is<br />
a field network system that processes both<br />
control and information data at high speed,<br />
to provide efficient, integrated factory and<br />
process automation. The dual functionality<br />
leads to a massive reduction in cabling requirements,<br />
and CC-Link is an ‘open’ system<br />
with many manufacturers making compatible<br />
control equipment for use with it.<br />
Because West Jutland is very flat lightening<br />
strikes are not uncommon. These can lead to<br />
transients in communication signals, so fibre<br />
optics was selected and repeater stations<br />
located at key points in the network.<br />
The master control installed at the central<br />
pumping station was a Mitsubishi Q-series PLC<br />
(programmable logic controller). This is connected<br />
to the fibre optic network through CC-<br />
Link compatible I/O modules made by Wago,<br />
which monitor a range of sensors and<br />
switches at each bore hole.<br />
The new control system monitors itself constantly<br />
and has high level diagnostic capabilities<br />
to determine the cause of any problems<br />
that are encountered. Further it uses predictive<br />
diagnostics, monitoring parameters such<br />
as ground water level and critical bearing temperatures<br />
to determine early if problems are<br />
likely to arise. This has reduced the running<br />
and maintenance costs considerable, despite<br />
the enlargement to the system.<br />
In normal operations, two, three or four boreholes<br />
feed the system, each working on a staggered<br />
two hour duty cycle before another borehole<br />
takes over. As demand increases more<br />
boreholes can be brought on line, although<br />
it only rarely goes above six working at<br />
once. All but one of the boreholes are fitted<br />
with a CC-Link controlled variable speed drive<br />
on its main pump, so that flow can be<br />
trimmed to exactly meet demand, and extraction<br />
is shared even over the system.<br />
Additionally each borehole is individually<br />
tested one night a month. This is done automatically<br />
over the CC-Link communications,<br />
putting the hole through a pre-defined 30<br />
minute routine that tests all its associated<br />
equipment and measures output of the<br />
ground water.<br />

Axellia is a leading producer<br />
of fermented anti-infective active<br />
pharmaceutical ingredients (API)<br />
and injectable finished products.<br />
To expand their manufacturing<br />
capacity for injectables, they<br />
invested in a complete compact<br />
liquid filling line solution with<br />
integrated end-of-line<br />
secondary packaging.<br />
Compact System Offers<br />
Filling and Packaging<br />
In order to meet its customers’ diversified requirements,<br />
Axellia recently began producing finished<br />
dosage forms of APIs into injectables.<br />
This enables the company to offer both raw<br />
APIs as well as finished products in an injectable<br />
format.<br />
Axellia’s existing filling line for injectables was<br />
exclusively devoted to powder filling, which<br />
was limited to only a few API products. To expand<br />
capacity for finished injectables and extend<br />
their portfolio to different API products, Axellia<br />
sought a liquid filling solution with sterile processing<br />
and lyophilisation capabilities. Due to the<br />
unstable nature of certain API products, they must<br />
be freeze-dried into dry powder form after being<br />
filled into injectable vials to ensure a reasonable<br />
shelf life of the finished product.<br />
Axellia ordered a complete filling line in the summer<br />
of 2007, consisting of a washing machine,<br />
sterilisation tunnel, filling and sealing machine,<br />
and an overseal capping machine. To meet the<br />
unique requirements of this project, the FLC<br />
3080 filling and sealing machine was chosen,<br />
which offers time-pressure filling, automatic<br />
cleaning-in-place (CIP) and sterilising-in-place<br />
(SIP) systems, and an automatic checkweighing<br />
system.<br />
Axellia specified the time-pressure filling system,<br />
instead of the traditional pump filling system,<br />
because it is easier to validate the CIP and SIP<br />
process. There are less mechanical parts in the<br />
time-pressure filling system compared to pump<br />
filling system, thus minimising maintenance<br />
and offering an easier cleaning and sterilisation<br />
process.<br />
The automatic CIP/SIP system feature of the machine<br />
offers some critical benefits to Axellia. It<br />
covers the in-line integrated sterilizing filter so<br />
there is no need to dismantle the system. The<br />
system complies with GMP regulations, minimis-
ing production times and eliminating the danger<br />
of product contamination.<br />
The fully automated, non-destructive checkweighing<br />
in-process control system ensures<br />
the best product quality control. With a speed<br />
of 300 vials per minute, the filling machine<br />
runs on an eight-hour shift. The checkweighing<br />
system controls eight random samples every three<br />
minutes and incorrect dosage amounts are automatically<br />
rejected without process interruptions.<br />
At the same time, the checkweighing system gives<br />
real-time in-process feedback to the time-pressure<br />
filling to ensure accurate dosing. This fully<br />
automated system reduces the necessity of<br />
having quality insurance engineers on site, thus<br />
reducing labour costs and minimising total<br />
costs of ownership.<br />
Uniquely for Axellia, the checkweighing inprocess<br />
control offers a tracking system designed<br />
in cooperation with the supplier of the freeze<br />
driers. This tracking system provides direct communication<br />
between the filling machine, the freeze<br />
driers and the capping machine, which ensures<br />
that incorrect vials will be automatically rejected<br />
even after the freeze-drying process. The<br />
whole automatic process and communication gives<br />
Axellia further quality assurance.<br />
When the complete filling line was delivered in<br />
the summer of 2008, the Project manager at Axellia,<br />
Mr. Knud-E Andersen, was impressed with<br />
the on-time delivery and the overall quality of<br />
the system. At the same time, he was also looking<br />
for an end-of-line secondary packaging solution<br />
to package the vials into cartons. Again<br />
Axellia turned to Bosch for a solution.<br />
For the end-of-line packaging, Axellia needed a<br />
labelling machine, a turntable, a cartoning machine,<br />
checkweigher, stretch bander and a case<br />
packer. However, Axellia didn’t want to source<br />
these individual modules from different suppliers.<br />
Bosch was able to offer a customised<br />
one-stop-shopping solution by sourcing the labelling<br />
machine, stretch bander and case packer<br />
from outside vendors and integrating them with<br />
its own cartoning machine and checkweighing<br />
unit. Thus, Bosch provided Axellia with a complete<br />
end-of-line packaging solution together with<br />
on-site installation and support.<br />
This service and support gives Mr. Knud-E Andersen<br />
the convenience of interacting with only one<br />
supplier and makes the whole line integration<br />
and validation process easier.<br />
The CUC cartoning machine offers excellent<br />
accessibility. The servo technology, industrial PC<br />
control systems and the ergonomic touch screen<br />
operating panel provide for secure, reliable and<br />
trouble-free production runs. The product insertion<br />
from the back of the machine significantly<br />
reduces maintenance time and provides for<br />
easier cleaning and trouble-shooting. The encapsulation<br />
of the drive components and the slanted<br />
guards considerably reduce the time required<br />
for line clearance.<br />
The modular checkweighing system KWE 4000<br />
meets pharmaceutical safety and cGMP requirements,<br />
as well as offering simple operation<br />
and easy line integration. The control cabinet at<br />
the rear of the checkweigher and the operator<br />
terminal allows excellent accessibility. Production<br />
statistics, trend curves and current weight<br />
are displayed on the standard screen which<br />
can be configured to show further information<br />
if required. The weight display can be altered to<br />
large numbers for remote readability by one<br />
single touch on the screen.<br />
“I have had a good experience with Bosch. We<br />
believe in Bosch, that’s why we buy it from<br />
Bosch,” said Mr. Knud-E Andersen.<br />

Level measuring and monitoring can<br />
be based on various technologies.<br />
The choice of the most suitable<br />
measuring principle is based on the<br />
medium to be measured. Further<br />
options include measuring or<br />
switching and contact<br />
or non-contact sensors.<br />
Methods & Technologies<br />
for Level Measurement<br />
Ultrasonic sensors, radar technology as well as<br />
some optical and capacitive sensors can be used<br />
for non-contact measurement, whereas with<br />
all other technologies, the sensors will have<br />
contact with the medium.<br />
Point Level vs. Continuous Level<br />
One of the main questions to be answered is<br />
whether one wants to measure at a point, or<br />
continuous level. Level switches have a proximity<br />
switch containing either one or two<br />
switch-points and indicate whether a certain<br />
level has been reached. Whereas this method<br />
only reflects the tank capacity at a certain point,<br />
a continuous measurement provides more<br />
detailed information by measuring the level via<br />
an analogue output signal. This very accurate<br />
method is often applied if liquids are to<br />
be dosed or mixed, or if adjustments, consumption<br />
or leakage are to be monitored.<br />
When choosing appropriate technologies and<br />
measuring methods, various factors have to be<br />
considered. The most important ones being container<br />
size, type and material, moving parts such<br />
as stirring devices in the container, the distance<br />
between minimum and maximum level, the<br />
medium’s consistence (conductive or nonconductive,<br />
homogenous or heterogeneous, temperature<br />
etc.). Additional factors like foam<br />
formation and foam detection, explosion hazard<br />
due to gas or dust, the accuracy of measurement<br />
required and the certificates needed<br />
(especially for applications in the fields of<br />
marine and food industry) may also need to be<br />
considered.<br />
Conductivity Based Level Measurement<br />
If the process medium is a conductive liquid,<br />
continuous or switch point measurement can<br />
be made using conductivity principle sen-<br />
sors. In conductive level switches, an output<br />
signal is connected to an insulated electrode.<br />
When the medium contacts the electrode, a<br />
minimal current flows through the medium to<br />
the housing. An electric booster collects this<br />
current and outputs it as a signal.<br />
A suitable device for continuous level measurement<br />
is LSP 05x. The reliable, easy to<br />
mount sensor conducts highly accurate measurements<br />
and is applicable with all mediums<br />
with a minimum conductivity of 50μS/cm.<br />
The measuring method is based on a low resistive<br />
measuring rod which dips into a conductive<br />
liquid. An oscillator generates an alternating<br />
current, which is fed to the whole<br />
measuring rod. Depending on the respective<br />
level, a proportional current flow is captured<br />
between the rod and the metallic tank wall or<br />
a reference electrode and then routed to an amplifier.<br />
The liquid’s resistance decreases proportionally<br />
to the immersed part of the rod. If<br />
the liquid is homogeneous, an absolute linear<br />
measurement of the fill level and thus a linear<br />
signal output of 4 to 20mA is provided. This<br />
level measurement device is ideal for use<br />
with tough or even pasty substances such as<br />
honey or tooth-paste. If foam formation impairs<br />
the measurement, a Teflon coating of the<br />
non-measuring part of the rod ensures there<br />
are no false signals.<br />
The fact that it is not affected by pressure, density,<br />
temperature or DK value opens up a wide<br />
application range for this technology. Due to<br />
the 3A-suitable process connection, the device<br />
can be used in the food and beverage industry<br />
as well as in pharmaceutical and biochemistry.<br />
One example for a special case is a company’s<br />
measurement of chocolate mousse,<br />
where a horizontal vessel meant the measuring<br />
rod could only be installed sideways.<br />
Therefore, the rod was angled 45° into the media<br />
and remained uncoated to ensure a signal<br />
path which served to record the level.<br />
Hydrostatic Level Measurement<br />
Level monitoring with the help of pressure measurement<br />
is a long-established method, with hydrostatic<br />
measurement being an easy-to-use<br />
and cost-efficient method. During this process,<br />
pressure sensors detect the hydrostatic pressure<br />
at the tank bottom which is directly pro-
portional to density and height of the liquid,<br />
therefore enabling the measurement of the liquid<br />
level. The devices have approval for hygienic<br />
applications and can be built into open or<br />
closed vessels as a standard feature.<br />
Whereas in open containers, a pressure measuring<br />
device mounted at the bottom of the tank<br />
detects the liquid level above the metering point,<br />
the internal pressure in closed containers is being<br />
measured via a second pressure transmitter<br />
mounted in the container tower.<br />
The difference between both values is the<br />
liquid level pressure, which is being indicated<br />
as fill level, volume or specific weight via<br />
either a downstream display or a controller. Since<br />
hydrostatical level measurement is independent<br />
of the medium’s viscosity and conductivity,<br />
foam forming or other substances in the tank,<br />
it is being applied in almost all industrial operation<br />
areas.<br />
Ultrasonic Readings Recorder<br />
With ultrasonic level detection, piezoelectric<br />
crystals in the sensor are being electrically activated<br />
to send out ultrasonic pulses. Reflected<br />
by the medium being measured, these impulses<br />
reach the sensor again after a short period<br />
of time and it is this varying delay that is<br />
used to measure the level. Therefore, this<br />
non-contact measuring method can be used<br />
in open or closed containers.<br />
The only factor to be considered is the sonic<br />
speed which depends on composition and<br />
temperature of the gas. Ultrasonic sensors<br />
are mainly used for the level monitoring of granulate,<br />
paste or liquid. For applications with aggressive<br />
liquids or gases, the standard sensors<br />
should only be used in measuring instruments<br />
with appropriate protection. To meet this requirement,<br />
UNAR sensors are equipped with a<br />
chemically resistant parylene coating with<br />
excellent barrier effects towards inorganic<br />
acid solutions, organic solvents and water<br />
vapour.<br />
Capacitive Sensors<br />
Capacitive sensors detect a medium by making<br />
use of its inductive capacity which is different<br />
to that of air. If a plate capacitor’s<br />
sensitive capacity is magnified due to external<br />
circumstances, a RC oscillator vibrates. The<br />
resulting reverse in current is analysed by<br />
the downstream functional unit and then<br />
leads – depending on the signal – to a circuit<br />
switch.<br />
This happens if the liquid or solid medium to<br />
be measured is located at a certain distance<br />
to the active area. The digital switch-point can<br />
be adjusted via potentiometer directly on<br />
the sensor. Capacitive sensors are usually<br />
maintenance-free and easy to install. They are<br />
used to monitor the level of diverse contact<br />
or non-contact media through a tank wall<br />
made of plastics or glass and can be used on<br />
non-conductive substances such as porcelain,<br />
wood, clay, pellets, paper, carton, powder,<br />
grain, tea or chocolate. The main fields of<br />
application are the chemical, food and plastics<br />
industry.<br />
Optical Sensors<br />
Optical sensors contain a glass quartz head carrying<br />
an infrared diode as a sender and a<br />
light-sensitive semiconductor as receiver.<br />
With these sensors, levels can be monitored<br />
without liquid contact via transparent or halftransparent<br />
conduits or tubes using a specially<br />
designed FFDK16 version.<br />
Since light is being used for the level detection,<br />
the optical method can measure conductive<br />
as well as non-conductive liquids. If<br />
the sensor head is surrounded by air, the limit<br />
angle for the total reflectance of the light<br />
changes.<br />
On the other hand, if the head made of borosilicate<br />
glass contacts liquid, the light beam is<br />
diverted into the fluid and the sensor output<br />
changes its switching status. FFAR is available<br />
with a variety of field mountable casings for<br />
different application conditions, for example<br />
May 2009 11<br />
stainless steel makes it extremely resistant to<br />
a great number of aggressive liquids. The liquid<br />
medium can either be conductive or nonconductive,<br />
as long as their reflection rate is<br />
not too high.<br />
Leakage Sensors<br />
Leakage sensors can safely and easily detect<br />
leaking liquids starting at a minimum of 1 ml,<br />
by using the optoelectronic method. With<br />
this procedure, a fast response time is achieved<br />
to keep the loss of liquid as small as possible<br />
and to avoid a contamination of the facility. Leakage<br />
sensors can be mounted directly at the tank<br />
bottom or on a supporting device.<br />
A reliable system for leakage control is very<br />
important in many areas, such as warehouses,<br />
conditioning cabinets, fuel deposits or with industrial<br />
machines. Only if leakages are detected<br />
early enough can according measures be taken<br />
and damages be prevented, for example by<br />
emergency cut-offs for pump systems.<br />
More methods for level monitoring<br />
In addition to the measuring methods mentioned<br />
so far, there are further technologies used for<br />
level detection and monitoring. Another noncontact<br />
method is radar which is based on the<br />
running time, from sending to receiving the reflected<br />
wave.<br />
For radiometric measuring, radioactive compounds<br />
are used as radiation source, and vibration<br />
sensors are level switches based on the<br />
vibrating-fork principle. There are also level<br />
switches based on magnetic gauges and flow<br />
rate sensors, mainly used in process technology<br />
to measure volume and mass flow necessary<br />
for accounting and dosing in charge<br />
processes.<br />
Costs<br />
When deciding for or against a measuring<br />
method, several process-related factors have<br />
to be considered – one of them being costs.<br />
Continuous level measuring is generally more<br />
complex and therefore more cost-intensive<br />
than proximity switches. However, acquisition<br />
costs should not be the decisive criteria,<br />
since in the long term, a more expensive<br />
measuring system can pay off thanks to low<br />
maintenance, high accuracy and integration<br />
possibilities in the control loop.<br />

Dynamic Arc Recognition and<br />
Termination (DART) is considered<br />
to be an important innovation for<br />
intrinsic safety applications. The<br />
dynamic, intrinsically safe electric<br />
circuit represents a new approach<br />
to eliminating the strict power<br />
limitations of applications in<br />
explosion hazardous areas.<br />
Dynamic Arc Recognition and Termination (DART)<br />
is a new technology developed by Pepperl+Fuchs<br />
that has met widespread recognition within the<br />
process control scene. Recently, interested process<br />
control experts met at the Physikalisch Technische<br />
Bundesanstalt (PTB) in Braunschweig,<br />
Germany to discuss the technical details of the<br />
new approach to intrinsic safety and agree on coordinated<br />
efforts for its introduction to the global<br />
process market. One major factor along the way<br />
is the fact that procedures for IS certification for<br />
DART are available, but they still need to be<br />
proven for introduction into IEC standards.<br />
Present solutions for intrinsically safe electric circuits<br />
strictly limit the power available to operate<br />
field devices inside explosion hazardous areas in<br />
order to prevent sparks that are hot enough to trigger<br />
an ignition. DART follows a completely different<br />
approach and is defined as a “dynamically acting<br />
intrinsically safe circuit.” This technology<br />
detects the current and voltage development<br />
typical of the formation of a spark and switches<br />
off the power source within milliseconds. With DART,<br />
present power limitations are obsolete, and current<br />
flow is now possible above the levels defined<br />
in IEC 60079-11 within the ex zone. All other aspects<br />
defining intrinsic safety, such as utilization,<br />
redundancy and general fault considerations remain<br />
untouched.<br />
The participants of the PTB workshop agreed<br />
that DART is a viable technology for electric explosion<br />
protection in the future. That is why the<br />
Intrinsic Safety Solution<br />
up for Standardization<br />
issue at the workshop was not whether the development<br />
of this technology should continue to<br />
drive toward general market acceptance but<br />
rather, how to achieve this goal. At the center of<br />
discussions was a common and coordinated approach<br />
to turn DART into a breakthrough technology<br />
in the field of intrinsic safety and gain global<br />
acceptance from the process industry. However,<br />
reaching this goal still requires the clarification<br />
of certain details. One of them is how to achieve<br />
a standard-compatible proof of the effectiveness<br />
of DART.<br />
The PTB relies on financial backing from the industry,<br />
in order to introduce DART to the market.<br />
A number of leading companies in the field of automation<br />
technology have agreed to provide the<br />
needed funds for the PTB to continue with the project.<br />
In particular, this includes the definition of safety-related<br />
parameters, as well as interoperability<br />
issues.<br />
The PTB is working with a leading institution in<br />
the field of technical thermodynamics to complete<br />
the basic research still required to establish<br />
DART as an industry standard. This project requires<br />
simulation of the chemical processes triggered<br />
by a spark under special conditions. The results<br />
will enable specific conclusions to be formulated<br />
for the evaluation of dynamic electric circuits.<br />
Pepperl+Fuchs has applied for international<br />
patents for their DART technology under the de-<br />
scription “electrical circuit with incentive arc<br />
prevention means” (WO 2006/003445). Using this<br />
technology, therefore, will require a license with<br />
both a one-time and an annual license fee. However,<br />
the company emphasizes that such costs will<br />
be required only until the technology has reached<br />
international standardization. As soon as this<br />
goal is achieved, the patent will be licensed free<br />
of charge to all interested companies.<br />
In other words, all switches are posed and there<br />
are no more obstacles preventing the introduction<br />
of DART as a future technology for explosion<br />
hazardous areas. That is why the participants of<br />
the PTB workshop are convinced that DART will<br />
be the enabling technology to pave the way for<br />
an intrinsically safe, Power-over-Ethernet concept.<br />
As far as ATEX certification is concerned, the<br />
PTB sees no basic problems, although the required<br />
documentation still needs to be completed.<br />
Since the required standard-compatible evaluation<br />
of DART is not possible until the research is<br />
complete, the next step will be the development<br />
of an IEC Technical Specification (TS). There<br />
are still quite a few steps on the way to IEC<br />
standardization. However, it is only a matter of time<br />
until this technology is part of the technical<br />
standard of the global process industry and opens<br />
completely new applications within the hazardous<br />
area.<br />

Proper specification and selection of<br />
sealing systems for centrifugal<br />
pump power frame applications can<br />
help sustain the service life of<br />
pumps and avoid the need for pump<br />
replacement or rebuilds and their<br />
associated costs in time and money.<br />
Pumps, Valves, Compressors<br />
Sealing Systems for<br />
Pumping Applications<br />
Sealing systems have their work cut out for<br />
them in pump applications. When a bearing<br />
seal in a pump fails, for example, contaminants<br />
have an opening to infiltrate both the bearing and<br />
the lubricant. Cleanliness of the lubricant will exert<br />
a profound effect on bearing service life.<br />
And should lubricant be lost from the bearing due<br />
to seal failure, dry-running operation ultimately<br />
could lead to premature and rapid failure of<br />
the bearings.<br />
Radial shaft seals have long been the most<br />
common types of sealing solutions for bearing<br />
arrangements in ANSI class pumps. In general,<br />
radial shaft seals will function as barriers to retain<br />
lubricant, and exclude contaminants.<br />
Labyrinth type seals, also known as bearing isolators,<br />
are specified for ANSI Enhanced and API<br />
rated process pumps and are gaining acceptance<br />
in other service classes. These seals feature a dynamic,<br />
non-contacting internal path to exclude<br />
fluid and particle contamination while retaining<br />
lubrication. They are based on metal or plastic<br />
material for chemical inertness and, when installed<br />
correctly, offer a very long service life.<br />
While the most suitable sealing systems for<br />
pumps will be governed by an application’s<br />
particular demands and operating conditions, some<br />
general guidelines can be offered to assist in making<br />
proper choices.<br />
In API-design centrifugal pumps (generally<br />
heavy-duty process pumps) bearings are usually<br />
located at two positions: A single-row deepgroove<br />
ball bearing near the impeller accommodates<br />
radial loads and floats in the housing<br />
(which allows thermal expansion of the shaft) and<br />
an angular contact ball bearing set is fixed in the<br />
housing in the thrust position at the coupling end.<br />
The angular contact set secures the impeller in<br />
the proper axial position and handles the thrust<br />
load and a portion of the radial load.<br />
Bearing locations in ANSI-design pumps (generally<br />
light- and medium-duty pumps) are similar<br />
to API configurations, except the angular contact<br />
ball bearing set is replaced by a double-row<br />
bearing (single bearings with two rows of balls<br />
in the thrust position).<br />
Bearing arrangements for pumps generally<br />
serve to enable smooth, efficient shaft rotation.<br />
Sealing systems will contribute to a bearing’s<br />
reliable operation and ability to reach<br />
full service life.<br />
Contacting radial shaft seal solutions typically will<br />
incorporate: A shell (sheet steel or elastomer<br />
covered) to which the lip material is bonded<br />
and provides the requisite interference fit of the<br />
seal in the housing bore; a sealing lip of elastomer<br />
or other material, which provides dynamic and static<br />
sealing against the shaft. In pump power<br />
frames, the sealing lip should always point toward<br />
the material to be retained. Most rubber sealing<br />
lips are made from a formulation of nitrile rubber.<br />
Some specially produced material variations<br />
have been introduced for use with synthetic<br />
fluids or chemically aggressive lubricants.<br />
Users can select from a wide variety of seal designs<br />
(and materials) to accomplish specific<br />
functions. Particularly in pump bearing applications,<br />
seals will be exposed to low and relatively<br />
constant pressure differentials so general purpose<br />
seals are sufficient. However some types of<br />
pumps utilize radial seals as the main pressure<br />
retention seal (in which the seal cavity is pressurized).<br />
Seal manufacturers offer particular lip<br />
profiles for this role that resist deformation under<br />
pressure loading and moderate surface<br />
speeds.<br />
In cases where higher shaft speeds are exhibited,<br />
the permissible pressure differential across the<br />
seal becomes smaller. As pressure is applied to<br />
the seal, more of the lip surface is forced against<br />
the shaft, which produces greater friction (as<br />
does increased shaft speed). Since too much<br />
friction will result in faster wear and shorter<br />
seal and shaft life, the two parameters (pressure<br />
and surface speed or PV factor) must be balanced<br />
against each other. Some radial designs,<br />
principally using PTFE lip material, can accept a<br />
PV in excess of 250,000 depending on the service<br />
life requirements.<br />
Specification of seals for pumps begins with selecting<br />
the correct general design for the application.<br />
For example, a spring-loaded radial sealing<br />
lip will usually be required to retain a head<br />
of oil or low viscosity fluid. Correct sizing for the<br />
hardware should follow (inch and metric dimensions<br />
and tolerances should not be mixed).<br />
For maximized service life and optimized seal performance,<br />
users then should evaluate all relevant<br />
operating conditions, which will further guide in<br />
seal selection. Among the key operating parameters<br />
when considering sealing systems in pumps<br />
is the surface speed. Each type of radial shaft seals<br />
has surface speed limits. Generally speaking,<br />
surface speed capability and parameters such as
Pumps, Valves, Compressors PRODUCT FOCUS May 2009 15<br />
seal torque, power consumption, under-lip temperature,<br />
and the effect of dynamic run-out will<br />
take inverse proportions. All these speed-related<br />
influences can ultimately contribute to shortened<br />
seal life.<br />
The majority of standard small bore radial seals,<br />
under 8 in. shaft diameter, are rated up to<br />
3600fpm (feet per minute) or 18.3m/s (meters<br />
per second), while the large diameter seals,<br />
over 8 in. shaft diameter, are rated to approximately<br />
5000fpm or 25.4m/s. Plastic bearing isolators<br />
can usually accept up to 5000fpm (25 m/s)<br />
while metallic versions can be capable of<br />
10,000fpm (50.80m/s). To exceed these speed<br />
recommendations typically calls for special design<br />
considerations.<br />
Design variations that can help combat the negative<br />
effects of higher shaft speeds include reducing<br />
the radial load of the seal lip; changing<br />
to a sealing material that can handle higher<br />
temperatures; changing the lubricant type or<br />
<br />
<br />

viscosity; optimizing the shaft sealing surface; and<br />
turning to a non-contacting labyrinth seal design.<br />
• Temperature. Each seal material has an optimum<br />
range. Beyond that, thermal stress will harden the<br />
compound (and heat aging is a more common cause<br />
of failure than wear for nitrile rubber). This can often<br />
be observed as subjective hardness or a series<br />
of radial cracks. Upgrading the seal material<br />
(such as to a fluoropolymer or PTFE) can extend<br />
a seal’s thermal limit to meet many pump system<br />
requirements.<br />
• Pressure. Pressure loading from system conditions<br />
or a fault (such as a plugged vent) will mechanically<br />
load and distort a seal’s lip profile, resulting<br />
in rapid wear and failure. Standard radial<br />
seals are designed for only about 7 psi (pounds<br />
per square inch). Special profiles and materials can<br />
be specified to compensate for pressure.<br />
• Surface finish preparation. For optimum radial<br />
lip seal performance and service life, a surface fin-<br />
ish of 0.20-0.43μm Ra is recommended with<br />
machine lead of less than 0 +/- 0.05°. Contact<br />
surfaces for labyrinth seals are less critical and finishes<br />
suitable for static o-rings are satisfactory.<br />
Rubber radial seals provide economical and versatile<br />
protection for bearings in pumps. Their contact<br />
with the shaft can deliver both positive fluid<br />
retention and hermetic sealing of the housing.<br />
But it should be understood that optimizing a sealing<br />
system is a balancing act. Careful definition<br />
of the application requirements, evaluating all<br />
conditions, and adopting a holistic approach to<br />
seal specification can contribute significantly to<br />
seal performance and service.<br />
Partnering at the outset with an experienced manufacturer<br />
of bearings and seals can help chart the<br />
most appropriate course for matching seal with<br />
pump application.<br />

In a large snack food plant, a<br />
Compressed Air Management<br />
system has helped to reduce energy<br />
bills, by combining the compressed<br />
air supply for production operations,<br />
integrating retrofit variable<br />
speed drives, reducing<br />
pressure and fine tuning.<br />
Pumps, Valves, Compressors<br />
Compressed Air Management<br />
Saves Energy at Food Plant<br />
The energy savings have been achieved by applying<br />
a combination of system pressure optimisation<br />
principles, matching air generation closely<br />
to demand, ensuring compressors are working<br />
at their optimum speed / efficiency, and operating<br />
compressors only when they are needed.<br />
The central element of control included in both<br />
sites is a SX control unit, a specialised supervisory<br />
and control module designed to provide optimised<br />
pressure and sequence management<br />
of all the air compressors on each site.<br />
Nigel Clark, EnergAir Regional Manager, comments,<br />
“The project began with an audit carried<br />
out on the two production areas that until recently<br />
used completely separate compressor houses<br />
and air ring mains. EnergAir carried out a comprehensive<br />
audit that measured system pressure,<br />
air usage and benchmarked a series of key performance<br />
indicators before the change and upgrade<br />
including; accurate metering of power consumption<br />
in kW/hours, air production volume<br />
in m 3 and efficiency in kW/m 3.”<br />
Analysis of the data led to a set of estimated<br />
results that predicted the energy savings<br />
achievable by fitting an management control<br />
system and retrofit VSDs at each site. There are<br />
seven compressors in total, three 160kW units<br />
and four 200kW units - production runs 24hrs.<br />
Based on the overall cost of installing the<br />
system balanced against the reduction in energy<br />
that could be achieved, the payback period<br />
was estimated at 18 months for the entire<br />
project.<br />
Based on these predictions, the Facility<br />
Co-ordinator at the time ordered the EnergAir<br />
system and retrofit VSDs. After seeing<br />
the potential this system had for achieving<br />
energy savings the customer was committed<br />
to installing it and getting the best<br />
results from it. Other plants with similar generating<br />
capacity have seen substantial<br />
recorded savings and so the project was<br />
quickly signed off. As predicted, the system<br />
did pay for itself after just eighteen months<br />
in operation.<br />
Most large manufacturing companies are<br />
firmly committed to reducing energy usage<br />
and it is a responsibility carried by members<br />
of the facilities and production teams.<br />
Large plants such as this are continually<br />
changing, and the level of visibility and fine<br />
control provided by the software has enabled<br />
the facilities team to continue making<br />
savings and improvements. For example, they<br />
have now connected the main air supply between<br />
both sites and use the EnergAir system<br />
to optimise overall system pressure and<br />
air generation in both compressor houses,<br />
but controlled and working as one.

The increases in efficiency are so pronounced,<br />
that they have been able to add another complete<br />
production line since the initial install, without<br />
having to upgrade the compressed air generation<br />
facilities and have maintained the increased<br />
efficiency levels - generating efficiency<br />
is now at 97.18%. The compressors are also<br />
being used to generate hot water for the site,<br />
something that they use a lot of on the production<br />
line. There are also plans to use hot air vented<br />
from the compressors through a heat exchange<br />
process for heating the building during the<br />
winter months.<br />
Pressure sensors are fitted throughout the system<br />
and used to feed live data into the EnerSoft<br />
– Analysis data management software<br />
that is hosted on an onsite PC, this<br />
collates and records all the data and makes<br />
it available to the EnerSoft – Visual PC visualisation<br />
package. The complete compressed<br />
air system, from compressor, through to the<br />
dryers and out across the plant is represented<br />
visually on screen in a Windows environment,<br />
with key indicators such as system<br />
pressure and efficiency displayed clearly on<br />
screen as analogue style dials.<br />
Through a series of SCADA style screens, the<br />
operators can drill down and check on the<br />
performance if individual compressors, set<br />
threshold alarms for performance variables,<br />
schedule servicing and maintenance tasks<br />
and crucially see the effect any changes<br />
made have on the system immediately.<br />
Using EnerSoft – Analysis data manager<br />
any of the Key Performance Indicators (KPIs)<br />
can be tracked over time and reported on at<br />
fixed intervals.<br />
The data is updated every few seconds and the<br />
information seen on the screen is virtually live,<br />
making it far easier to accommodate changes<br />
to the plant and make positive changes to keep<br />
efficiency maximised, every time a change is<br />
made, the results are displayed instantly. Prior<br />
to having the EnergAir system the facilities<br />
team had to collate data over a period of<br />
time using much cruder indicators such as energy<br />
bills and it was a minimum of ten days<br />
before we could see the results, in that time<br />
other factors could have cancelled out the improvement<br />
they made and they would never<br />
be completely sure how effective the change<br />
had been.<br />
One thing in particular that has shown great<br />
savings and can be tweaked onsite is the<br />
overall system pressure, there are certain<br />
limits to how low it can go based on manufacturers<br />
recommended minimum operating<br />
pressures for machinery on the production line,<br />
some of which were set quite high.<br />
After consulting the machinery manufacturers<br />
it was discovered there was a large overestimate<br />
made in some cases to offset the effects<br />
of the machinery being used in plants<br />
with little or no accurate secondary pressure<br />
sensing facilities. The team has been able<br />
to safely reduce the overall system pressure<br />
by over half a bar in increments. The savings<br />
achieved by that half a bar reduction are<br />
substantial bearing in mind the site uses<br />
over a Megawatt of generating capacity just<br />
for compressed air.<br />

Dispensing Biopharmaceuticals:<br />
Peristaltic or Piston Pumps?<br />
Traditional filling technology based<br />
on piston pumps and time pressure<br />
filling systems, but new challenges<br />
and stringent validation requirements<br />
have put the focus on peristaltic<br />
pumps. They are now often<br />
preferred for fluid transfers in all<br />
types of environments.<br />
The pharmaceutical industry has had to adapt to<br />
major changes and challenges over the last<br />
decade. This has been mainly driven by the fact<br />
that many of the blockbuster drugs are running<br />
out of patent, forcing the industry to focus more<br />
on R&D with greater interest towards developing<br />
biopharmaceutical products. This trend has<br />
highlighted the need for efficient, small batch,<br />
aseptic liquid processing and fill/finish operations.<br />
In addition, ever-increasing FDA demands, especially<br />
regarding cleaning validation, have forced<br />
the industry to look for more efficient and safer<br />
production technologies.<br />
The traditional filling technologies have been piston<br />
pumps and time pressure filling systems, but<br />
new challenges and more stringent validation requirements<br />
have put the focus on peristaltic<br />
filling technology.Peristaltic pumps are extremely<br />
convenient to use. They are often the preferred<br />
choice for fluid transfers in all types of environments<br />
such as in the laboratory or in the heavy<br />
chemical industry.<br />
On the other hand, piston pumps are also very<br />
popular and have proven themselves over the years,<br />
but piston pumps can have drawbacks in some<br />
applications. A piston pump is designed with many<br />
mechanical parts such as valves and seals that<br />
are in direct contact with the product. These<br />
components, which will wear out, need to be taken<br />
apart, cleaned and re-assembled between<br />
each use. Even the high-end valveless ceramic<br />
piston pump comes into direct contact with the<br />
product. Additionally, diligent care is required to<br />
prevent damage to the piston in these extremely<br />
fragile pumps.<br />
When using peristaltic pumps, product only<br />
comes in direct contact with a single piece of tubing,<br />
which can easily be replaced after use. This<br />
single-use feature makes the peristaltic pump an<br />
Pumps, Valves, Compressors<br />
attractive alternative to piston pumps for dispensing<br />
of biopharmaceutical injectable drugs.<br />
For the last few years, the pharmaceutical industry<br />
has been searching for ways to reduce the cost<br />
for developing and producing new drugs. The concept<br />
of the disposable or single-use production<br />
factory is becoming a reality. As a point of<br />
reference, it is important to note that while<br />
most of the existing drugs used today are chemically<br />
based, most of the promising new drugs<br />
are biopharmaceuticals which are developed<br />
in liquid form.<br />
An innovative breakthrough for making peristaltic<br />
pumps accurate occurred 21 years ago when<br />
Flexicon A/S of Denmark created the “pulsationfree”<br />
peristaltic pump.<br />
Once pulses were removed, the potential for<br />
high accuracy dispensing was made possible. Today,<br />
and five generations of improvements later,<br />
peristaltic dispensing pump accuracy rivals piston<br />
pumps down to micro fill volumes.<br />
Two key design features allow the peristaltic<br />
pump to be accurate for dispensing:<br />
• The use of multiple rollers<br />
• The removal of the typical peristaltic flow pulses<br />
by using offset rollers<br />
It has been determined that the optimal configuration<br />
for a pump head design is to have two<br />
sets of six rollers, with each set of rollers offset<br />
with respect to one another. As the product is<br />
drawn by two tubes through the pump head, they<br />
merge into a single tube via a y-connector, and<br />
thereafter, the pulses add-up to cancel each<br />
other. The resulting pulsation-free flow is then<br />
controlled using a precise positioning motor<br />
and special software allowing for accurate dispensing.<br />
There is a huge selection of tubing available<br />
made of many materials and of various sizes, many<br />
of them made specifically for peristaltic pump use.<br />
Nonetheless, to allow for consistently accurate<br />
dispensing down to the micro litres, it is imperative<br />
that both the tubing and the pump head be<br />
designed to work together from the beginning and<br />
that they both must have close dimensional<br />
tolerances.<br />
Key mechanical characteristics in the selection<br />
of peristaltic pump tubing include: uniform wall<br />
thickness, consistent material hardness and<br />
high mechanical “memory” after compression<br />
Finally, and in consideration of dispensing injectables,<br />
the silicone tubing must be of the highest<br />
quality to meet the FDA’s good manufacturing<br />
practices requirements (cGMP).<br />
When compared to piston pumps and other dispensing<br />
technologies, peristaltic pumps offer<br />
the following benefits:<br />
• One Pump Can Fill a Wide Range of Fill Volumes<br />
- A single peristaltic pump can fill volumes<br />
between 0.1 ml to 250 ml, simply by<br />
changing the tubing size. More than one piston<br />
pump would be required to meet a similar<br />
fill range.<br />
• Fast Set-up and Calibration - It can take less<br />
than 5 minutes to load the tubing, purge the<br />
system, make one calibration and begin filling.<br />
• Cross-Contamination - Peristaltic pumps do not<br />
require cleaning when utilized for single-use<br />
dispensing, since each batch is produced with<br />
new tubing that creates a new fluid path or set<br />
of contact parts. In comparison, when filling<br />
injectable drugs on a traditional piston filling<br />
line, it is not uncommon to buy dedicated<br />
piston pumps for each product in order to<br />
prevent cross-contamination between batches.<br />
Those pumps require cleaning, sterilizing<br />
and maintenance.<br />
• Greatly Reduced Cleaning Validation - Cleaning<br />
validation is a cGMP requirement to<br />
demonstrate and document that the equipment<br />
used for processing an injectable drug is clean<br />
and free from contaminants<br />
For a multiple-use piston pump filling system,<br />
cleaning validation typically requires two qualified<br />
resources up to four months to write-up the<br />
protocols and execute them. For each subsequent<br />
production batch, cleaning in accordance with<br />
the validated procedures has to be maintained<br />
and properly documented each time throughout<br />
the drug’s commercial life.
Pumps, Valves, Compressors PRODUCT FOCUS May 2009 19<br />
In addition to these labor costs are other costs<br />
associated with the use of water for injection<br />
(WFI), for washing, rinsing, and for sterilization<br />
using pure steam and finally the cost of detergents<br />
and water disposal.<br />
• Flow Control - It is very easy to adjust flow<br />
speed via the peristaltic pump interface in order<br />
to prevent foaming or splashing of the product.<br />
It is also possible to adjust how fast<br />
the fill speed is reached using the ramp-up<br />
and ramp-down feature. This is helpful in<br />
optimizing overall fill time to permit greater<br />
throughput from the filling machine.<br />
• Gentle Handling for Shear Sensitive Products<br />
- The valve system in the piston pump generates<br />
high-speed flow through small orifices,<br />
which can potentially damage biological<br />
products. Even valve-less piston pumps<br />
generate higher pressures, higher shear factors<br />
and, by design, inherently produce a<br />
“dead volume” with each stroke. Peristaltic<br />
pumps are valve-less and only apply low<br />
pressure to move the product.<br />
The typical industry standard for fill volume accuracy<br />
is ±0.5%. Peristaltic dispensing pumps<br />
meet this requirement for fill volumes as small<br />
as 0.5 ml. Below that fill volume, accuracy<br />
can be as good as ±1%.When peristaltic pumps<br />
are integrated into highspeed filling machines,<br />
an automated closed-loop weight-check weight<br />
control system assures that the fill volumes remain<br />
within tight tolerances.<br />
While piston pumps need to cycle through a recovery<br />
or suction phase between each dispensing<br />
stroke, there is no such downtime required<br />
with peristaltic pumps. Consequently,<br />
peristaltic pumps will dispense product immediately<br />
upon demand.<br />
The high-end peristaltic dispensing pumps are<br />
designed to run at high RPM to minimize fill<br />
time. They are equipped with a control system<br />
that provides an immediate response from a filling<br />
machine input signal. Therefore, using a peristaltic<br />
dispensing pump instead of a piston pump<br />
will not slow down the filling process. It is now<br />
commonplace to have high speed filling lines<br />
with peristaltic pumps that fill at rates over 400<br />
bottles per minutes.<br />
Peristaltic pumps have limiting capabilities<br />
for dispensing viscous products. In general, a<br />
product with the viscosity of olive oil can be dispensed<br />
using peristaltic pumps. Slightly higher<br />
viscous products will also work, but may exhibit<br />
potential loss in accuracy and flow rate.<br />
While piston pumps have the capacity to generate<br />
significantly greater pressure for dispensing<br />
more viscous products, high-end peristaltic<br />
dispensing pumps do not. In fact, one of<br />
the underlying principles in achieving accurate<br />
peristaltic dispensing down to the micro fill volumes<br />
is to apply very little pressure on the tubing.<br />
When used for micro filling, peristaltic<br />
pumps are calibrated to provide no more than<br />
approximately 1.3 bar of pressure.<br />
In recent years, biotech companies have embraced<br />
single-use technology, an efficient method for<br />
developing and bringing new drugs to market.<br />
Single-use process components such as small<br />
reactors, filters, mixers and fluid handling bags<br />
have been available for the last few years. The<br />
use of peristaltic pumps and single-use tubing<br />
is also becoming more commonplace as it allows<br />
for simple fluid transfers with no cleaning<br />
and no risk of cross contamination.<br />
New drugs and, in particular, biopharmaceutical<br />
drugs are often designed for a specific<br />
population. Therefore, they are more likely to<br />
be made in relatively small batches than general<br />
application “chemical” drugs. As new<br />
drugs evolve to offer a more specific spectrum<br />
of applications, batch sizes are becoming<br />
smaller and the need for efficient product<br />
changeovers on the filling lines will become<br />
greater.<br />
Many articles about single-use technology<br />
have been written regarding efficient use of the<br />
utility and process equipment for upstream<br />
processing. Benefits of single-use technology<br />
include reduced labor, equipment and energy<br />
costs, increased plant flexibility and faster<br />
turnaround with significantly less risk of contamination.<br />
In addition to R&D, there is now a requirement<br />
for greater reliability and efficiency for the<br />
fill/finish side of mass manufacturing of biological<br />
drugs. Therefore, it is expected that<br />
single-use technology will make its way in<br />
production facilities where accurate peristaltic<br />
dispensing pumps can eventually replace pis-<br />
tons and other mechanical dispensing systems,<br />
potentially allowing for 100% singleuse<br />
drug manufacturing.<br />
Until now, the pharmaceutical industry has<br />
used single-use silicone tubing and fittings<br />
for peristaltic dispensing but has not been<br />
able to provide a single-use filling nozzle. In<br />
an effort to offer a complete solution to singleuse<br />
aseptic filling, Flexicon developed a plastic<br />
nozzle for single-use applications.<br />
It is now possible to purchase single-use ready<br />
to-use tubing set assemblies. These sets include<br />
the required pharmaceutical grade silicone<br />
tubing, connectors and single-use filling nozzles.<br />
The assembly is double bagged and Gamma<br />
irradiated and includes a complete validation<br />
package.<br />
Various single-use tubing set configurations are<br />
available. These may include a sterile filter, septic<br />
quick-connect fittings and a pre-filled product<br />
bag. In most cases, tubing and connectors<br />
ring the product directly from the product<br />
holding tank to the filling nozzle for dispensing<br />
on the filling machine— making the entire<br />
process singleuse.<br />
The pharmaceutical industry is implementing<br />
single-use technology in both the R&D laboratory<br />
and large scale production of injectable<br />
drugs. Peristaltic pumps have benefited from<br />
major technological improvements that have<br />
made them very accurate, fast, and reliable. Today,<br />
single-use peristaltic pumps offer a serious<br />
alternative to piston pumps for the production<br />
of biopharmaceutical drugs.<br />

DSM Composite Resins in Ellesmere<br />
Port, UK, one of Europe’s leading<br />
manufacturers of polyester resins,<br />
replaced some of its ageing<br />
magnetically coupled pumps by<br />
canned motor pumps, resulting<br />
in significant savings.<br />
Reducing maintenance costs and cutting energy<br />
bills has always been high on the agenda for<br />
most manufacturers, but never been more important<br />
than in the present situation of high energy<br />
costs and difficult economic climate. For<br />
applications where pumps are operating 24<br />
hours per day, 7 days per week this cost-saving<br />
‘focus’ is especially important and when investigated<br />
and acted upon, can result in significant<br />
savings. A good example is at DSM Composite<br />
Resins in Ellesmere Port, Cheshire, one of Europe’s<br />
leading manufacturers of polyester resins.<br />
In 2006 DSM Resins made the decision to replace<br />
some of its ageing magnetically coupled<br />
pumps which were operating on Jarytherm<br />
hot oil service, operating at 250ºC. These<br />
hot oil pumps were running 24/7, as part of a<br />
system providing an instant source of heat for<br />
the chemical reactors used for the resin production.<br />
Nikkiso high temperature HX Series canned<br />
motor pumps, supplied by Michael Smith<br />
Engineers, UK, were identified as the<br />
most suitable pumps to replace the existing<br />
magnetically coupled pumps.<br />
Pumps, Valves, Compressors<br />
Canned Motor Pumps<br />
Help Reducing Costs<br />
The pump selected was an HX25D-G5 with a<br />
30kW motor and produced an immediate efficiency<br />
improvement over the original 45kW<br />
magnetically coupled pumps. On the same duty<br />
service the Nikkiso drew 23kW, compared<br />
to the original pumps 45kW, a saving of 40%<br />
on energy operating costs. Commenting on<br />
the pump’s performance, Graham Wilkes,<br />
<strong>Industrial</strong> Engineer for DSM Composite Resins<br />
said, “The pump paid for itself within 12<br />
months due to the energy savings and reduced<br />
maintenance costs, we are very pleased with<br />
the results”.<br />
Two smaller HX24C-C5 pumps with 18.5kW motors<br />
were installed at DSM Resins in July<br />
2008 and once again produced instant efficiency<br />
benefits. These pumps drew 5.88kW and<br />
11.33kW, compared with the original magnetically<br />
coupled pumps which drew 17kW and<br />
18kW respectively.<br />
However, the benefits are not just lower running<br />
costs, HX pumps also ensure savings on<br />
installation. This is because most magnet drive<br />
pumps operating on applications where temperatures<br />
are 250º C require cooling water to<br />
prevent the magnet area from overheating<br />
and the magnet strength weakening. The series<br />
has a ceramic stator which requires no external<br />
cooling. This results in significant savings<br />
on installation as there is no need for<br />
additional pipe work required to bring a water<br />
supply for cooling and an operating cost saving<br />
as there is no need for cooling water.<br />
Other features and benefits of the canned motor<br />
pumps include a one piece rotor/pump<br />
shaft, so any misalignment problems, and the<br />
subsequent maintenance issues associated<br />
with conventional pumps, are eliminated. Also,<br />
the pumps have only 2 journal bearings and<br />
a patented automatic thrust balancing<br />
system which ensures that both the axial and<br />
radial bearing loads are kept to a minimum.<br />
This results in longer bearing life and therefore<br />
reduced maintenance costs.<br />
The canned Motor Pumps can handle capacities<br />
up to 1000m3/hr and maximum discharge<br />
heads up to 210 metres. High speed<br />
and multi-stage options for differential heads<br />
up to 420 metres are available. These compact,<br />
energy-efficient, leak-free pumps are suited<br />
for handling corrosive, aggressive or expensive<br />
liquids which must not come into contact<br />
with the atmosphere.<br />

From deep seas to productive fields,<br />
polymer products and solutions<br />
help to seal, damp, and protect<br />
in water and food applications.<br />
Here are some examples of<br />
that happening in practice.<br />
Polymer Products Used in<br />
Food and Water Applications<br />
In food production, polymers are at hand from<br />
the very beginning. In the cultivation of fields<br />
for crop growing, tires protect the soil from<br />
unnecessary damage. Once the crops are harvested<br />
and being processed, seals, millions of<br />
which are fitted throughout food processing<br />
systems, help prevent contamination, even in<br />
difficult and demanding dairy production. This<br />
is also the case for high technology hoses,<br />
which are regularly used by wine producers for<br />
all the best vintages. Finally, at the end of the<br />
manufacturing process, trucks equipped with<br />
damping solutions transport these essentials to<br />
consumers worldwide.<br />
With regard to water-related products, rubber is<br />
vital in certain critical applications. Sealing<br />
products are used extensively in the treatment<br />
and transportation of drinking water. They range<br />
from large gaskets used in wastewater treatment<br />
plants and infrastructure, to tiny but equally important<br />
O-Rings found in faucets in homes.<br />
Globally, as the sea levels are rising land protection<br />
is of growing concern. Technology used<br />
for flood defense systems in flood-prone countries,<br />
such as the Netherlands, is being transferred<br />
to projects worldwide. In this type of application,<br />
rubber products help to waterproof foundations<br />
and divert watercourses.<br />
Congested roads are also becoming an increasing<br />
problem, particularly around metropolitan<br />
areas. With little land to divert traffic to, underground<br />
road tunnels are becoming longer and<br />
larger. Gaskets are an integral part of these, preventing<br />
water ingress into underground arteri-<br />
Chemical Industry<br />
al routes.Polymers are also present in a wide range<br />
of seawater applications, such as mooring systems<br />
that protect ships when docking in harbour.<br />
Subsea rubber and polymer products contribute<br />
to the safety of personnel and equipment involved<br />
in oil and gas exploration. One example is VIV<br />
suppression products that protect pipelines<br />
from the destructive vortex-induced vibrations<br />
caused by underwater currents.<br />
Water-filled onions<br />
Collapsible water storage containers can be<br />
supplied in two formats, either pillow shaped or<br />
‘onion’ shaped. The pillow shaped tank is ideal<br />
for water and other aqueous solutions and has<br />
a standard capacity range of 3,700 to 75,000 litres,<br />
while the onion tanks are specifically designed<br />
for storage of potable and non-potable water and<br />
have a capacity range of 3,780 to 11,350 litres.<br />
The onion tank comes in three configurations<br />
– open top, roll top, to keep contamination<br />
out, and zipper top, which prevents both contamination<br />
and evaporation. Both formats are<br />
easily rolled up and transported and can be<br />
custom ordered to specific capacities. Pumps,<br />
hoses and water distribution sets are part of the<br />
solution, making the water containers suitable<br />
for both military authorities and relief agencies.<br />
Processing food<br />
In a processing plant, processing dairy products<br />
or other kinds of food, there are thousands of<br />
lengths of piping and at each juncture there is<br />
a coupling sealed with clamp gaskets and O-Rings.<br />
Ineffective sealing frequently results in production<br />
stops for maintenance, or even unplanned<br />
part replacements. Carefully matching<br />
the seal material to the process media and the<br />
aggressive chemicals used in cleaning regimes<br />
maximizes the life of seals and gaskets. This improves<br />
production efficiency, reducing overall costs<br />
for the manufacturer. From high-performance<br />
EPDM elastomer compounds to advanced materials,<br />
such as Resifluor and the perfluoroelastomer<br />
Isolast, the right sealing material for diverse<br />
operating conditions are available.<br />
Mega gates block the flood<br />
In one of the world’s largest flood prevention<br />
projects, the Delta Project in the Netherlands,<br />
the Maeslantkering storm-surge barrier protects<br />
the land from the powers of the water. The<br />
massive structure consists of two hollow “gates”<br />
with 248 one-meter-high fenders, constructed<br />
by Trelleborg Bakker. Each gate’s arm length<br />
is 237 meters, from ball joint to the tip. When<br />
the gates are folded into their two docks, each
is supported by 14 spring-like elastomeric bearings.<br />
In the event of a storm tide, the docks are<br />
filled with water and the hollow gates start to<br />
float, and turn outwards until they meet. As the<br />
gates’ cavities are filled with water, the gates<br />
sink and seal off the 360-meter-wide water<br />
opening. After the high water has passed, the<br />
water is pumped out and the structure begins<br />
to float again. Once the risk of high water has<br />
passed, the two gates are returned to their<br />
docks. During a huge storm in November of 2007,<br />
the storm-surge barrier was closed for the first<br />
time. The barrier will only be closed in<br />
extremely bad weather – probably once every<br />
ten years.<br />

The Evonik Degussa carbon black<br />
factory uses residual gas for steam<br />
and electricity generation in the<br />
thermal afterburning plant. A safety<br />
system was installed to automate<br />
the boiler control and monitoring<br />
system for the gas flare.<br />
Evonik Industries is a global leader in specialty<br />
chemicals, an expert in power generation<br />
from hard coal and renewable energies, and<br />
one of the largest private residential real<br />
estate companies in Germany. Evonik is active<br />
in over 100 countries around the world.<br />
With the product lines Carbon Black, Silica,<br />
Aerosil and Silane, the business division Inorganic<br />
Materials is one of the most important<br />
strategic activities of Evonik Degussa<br />
GmbH. Carbon Black remains the dominant<br />
reinforcing filler for the rubber industry, in particular<br />
for manufacturing tyres, but also with<br />
diverse uses in paint, printer colours, ink<br />
and synthetic materials. With 1.2 million<br />
tonnes, Degussa is the second largest producer<br />
of Carbon Black.<br />
Chemical Industry<br />
Safety System Automates<br />
Burner Control System<br />
The Evonik Degussa GmbH factory near<br />
Cologne, Germany, is the largest European<br />
producer of carbon black. During the production<br />
of carbon black, the residual gas is<br />
used for steam and electricity generation in<br />
the thermal afterburning plant. If a boiler stops<br />
functioning, however, a gas flare system<br />
starts operation to burn the residual gas. As<br />
part of renovation work, the boiler control<br />
and monitoring system for the gas flare<br />
was automated using the safety system HI-<br />
Max.<br />
The solution included two HIMax-CPUs, two<br />
system bus modules, two digital output and<br />
three input modules, one analogue input<br />
module and one communications module for<br />
PROFIBUS-DP. The function of these components<br />
is to maintain overall correct operation,<br />
particularly in regard to the pre-ventilation<br />
period, flare monitoring and correct<br />
operating parameters.<br />
Lutz Dross, PLT planning and process engineer<br />
for the IM business division Evonik<br />
Degussa GmbH, values the possibility to<br />
conduct online tests with HIMax as well as<br />
the diverse programming possibilities. “The<br />
high level of flexibility guarantees low<br />
costs during the entire lifecycle of HIMax.<br />
Another advantage is that the safety system<br />
can be easily expanded without interrupting<br />
operations.” The new safety control<br />
system from HIMA guarantees the highest<br />
possible level of availability, Dross added.<br />
Whether during a hardware or software<br />
upgrade or routine maintenance work,<br />
HIMax doesn’t have to be turned off – the<br />
plant continues to operate.<br />
The safety system HIMax for large and medium-sized<br />
applications allows for uninterrupted<br />
operation of processing plant over its<br />
entire lifecycle. It is based on the Nonstop<br />
XMR technology that combines diagnostic-based<br />
SIL 3 safety integrity with a scalable<br />
fault-tolerant architecture that eliminates<br />
false trips and provides for unlimited<br />
changes, modifications, expansions, upgrades<br />
and regulatory proof testing without<br />
taking the plant off-line.<br />
The HIMax system is integrated into the<br />
Foxboro processing control system (DCS)<br />
via PROFIBUS-DP. Because of the open standards<br />
protocol, HIMax can be integrated<br />
with all leading DCS. In this way, controls can<br />
be combined with the best-suited DCS.<br />
The software tool SILworX proved to be another<br />
major benefit, said Lutz Dross, because<br />
of the fully integrated configuration, programme<br />
and diagnosis environment for HIMax.<br />
The modern user interface contributed to a reduction<br />
in mistakes and accelerated planning<br />
and implementation. “HIMax is exceptionally<br />
user-friendly. The software tool SILworX has<br />
a fully-graphic drop and drag programming<br />
function. That simplified engineering enormously,”<br />
said the management technology specialist<br />
from Evonik Degussa.<br />

The plastic Ecovio consists of Ecoflex and of polylactic<br />

Ecoflex is a petro-chemical-based polyester. And<br />
yet, thanks to its special molecular structure, it can<br />
be digested by microbes under precisely defined<br />
conditions: it is completely biodegradable according<br />
to European standard EN 13432. Whereas<br />
Ecoflex makes the bag flexible, tear-resistant,<br />
waterproof and suitable for printing – giving it the<br />
properties of a classic plastic – the stiff PLA contributes<br />
the renewable raw material. The combination<br />

A Large Area Rotary Filtration<br />
System replaces a duplex candle<br />
filter in a line for the production of<br />
PVC film (interlayer for laminated<br />
glass), eliminating the process<br />
disturbances from filter changes<br />
while saving money.<br />
Chemical Industry<br />
Rotary Filtration Systems<br />
for Large Scale Applications<br />
A process-constant Filtration System type RSFgenius<br />
330 will replace a duplex candle filter in a<br />
line for the production of PVC film (interlayer<br />
for laminated glass). The operation of the RSFgenius<br />
330 will ensure that the process disturbances,<br />
which had hitherto been a problem when<br />
switching from one candle filter to the other prior<br />
to filter changes are completely avoided, in addition<br />
to the costs for dismantling, handling and<br />
cleaning the candle filter elements. An additional<br />
important advantage in the processing of this<br />
high viscosity material is the absolute pressure<br />
stability ensured by the Rotary Filtration System<br />
which guarantees a constant film thickness.<br />
The RSFgenius, with its Rotary Filtration System<br />
in this case is characterised by a filtration area<br />
of 1,900cm 2 and operates with a filtration fineness<br />
of 56μm. The throughput rate is 2,800kg/h.<br />
When increasing the number of recycling lines<br />
from 3 to 4, a major French manufacture of recycled<br />
PET bottle grade chip/pellets from post<br />
consumer PET bottles once more selected the<br />
Rotary Filtration System. The RSFgenius Filtration<br />
Systems already in operation at this customer<br />
have a filtration area of 590cm 2 and operate with<br />
a throughput rate of 1,500kg/h and a filtration<br />
fineness of 56 microns.<br />
The trademark characteristic of the Rotary Filtration<br />
Systems is the disc, which rotates between<br />
the inlet and outlet blocks and which is equipped<br />
with a set of filter elements, located in a ring<br />
pattern around the disc. The polymer melt flows<br />
across the filter surface, leaving the contamination<br />
on the filter elements. As a result, the<br />
pressure differential increases slightly and the<br />
control system reacts immediately, rotating<br />
the disc by approximately 1° angle at a time. In<br />
this way, contaminated filter area is indexed out<br />
of the melt channel and clean area is introduced<br />
at the same time.<br />
Additionally, the RSFgenius is equipped with an<br />
integrated high pressure sequential self cleaning<br />
system which ensures complete cleaning of<br />
the filter elements. Depending on the filtration<br />
fineness, the filter elements can be used as<br />
many as 400 times, which in this case results<br />
in an interval between filter element changes<br />
(which can be carried out without disturbing the<br />
process) of approximately 2 months.<br />
All the Gneuss Melt Filtration Systems operate<br />
“gneussconstant” – in other words, they operate<br />
fully automatically and ensure pressure<br />
and process constant production at all times. They<br />
are available in a range of different model sizes<br />
with filtration areas from 25cm 2 up to 17,400cm 2<br />
for throughput rates from 190 to 32,000 kg/h.<br />
A manufacturer of cable compounds for high Voltage<br />
cables (> 2,500kV) from LDPE and which are<br />
cross linked in a second processing step needed<br />
a flow optimised melt channel design and extremely<br />
fine filtration (20μm). The manufacturer<br />
selected the KSF Melt Filtration System,<br />
designed so that the screws of the twin screw<br />
extruder reached to within 10mm of the filter<br />
elements. In this way, the high viscosity<br />
material is agitated through the inlet block,<br />
the residence time spectrum is kept narrow,<br />
the polymer flow is fast and streamlined.<br />

Plant monitoring and control is<br />
particularly vital in the continuous<br />
process industries, where multiple<br />
machines must act in harmony<br />
day after day. With most machines<br />
driven through a rotating shaft,<br />
torque monitoring can identify<br />
problems before they become critical.<br />
Say ‘process control’ and most people automatically<br />
think of monster-sized central computers running<br />
barely-fathomable SCADA software in a control<br />
room that would not be out of place at Cape<br />
Canaveral. But out on the plant floor, there may be<br />
literally thousands of simple sensors and switches,<br />
collecting data and feeding it back to the Beamoth.<br />
These sensors are tracking every little change in the<br />
plant’s operating parameters, indicative of either the<br />
state of the materials being worked or of the state<br />
of the machinery itself. For instance an increase in<br />
torque on a mixer drive may suggest that a mixture<br />
within is thicken up as expected, or alternatively that<br />
a seal or bearing is sticking and may soon fail al-<br />
Torqing Sense for<br />
Process Plant Control<br />
together: either way this is vital information for the<br />
central computer to capture and assess.<br />
Ultimately, process engineers want to transform material<br />
from one state to another, and to monitor variables<br />
indicative of the various stages of the process.<br />
Some parameters can be measured directly and simple<br />
– temperature for example. Others are more difficult<br />
to measure, so an often-used technique is to<br />
measure a related parameter (typically one related<br />
to the plant or machinery rather then the<br />
process material) and interpolate from this.<br />
Significantly many types of process plant – mixers,<br />
pumps, conveyors - are motor driven, and measuring<br />
the motor output characteristics will often provide<br />
process information. For instance, the torque<br />
of the motor could suggest the quantity, speed or<br />
viscosity of the process material being worked.<br />
Obviously, measuring the processing is the primary<br />
concern of the production engineers, but<br />
torque measurement has a second, equally important<br />
function. Because you are actually measuring<br />
plant performance, you get to see how the machinery<br />
is holding up. Knowing what to look for will give<br />
you early warning of breakdowns, allowing you to<br />
schedule pre-emptive maintenance. For a continuous<br />
process where downtime can cost thousands<br />
of Euros an hour in lost production, this can be critical<br />
- ultimately the difference between healthy profit<br />
and catastrophic loss.<br />
This all sound very useful, and actually measuring<br />
torque can be very simple. Not so long ago torque<br />
sensors required a fairly complicated and fragile array<br />
of slip rings connected to the rotating drive shaft<br />
of the machine under test. TorqSense provides a noncontact<br />
means for taking the readings. In use, a couple<br />
of simple pads are glued to the side of the driveshaft<br />
and a TorqSense unit mounted close by. The<br />
device then starts monitoring torque, and feeding<br />
it as a data signal to the SCADA control system.<br />
Principles<br />
The pads are in fact tiny little piezoelectric combs<br />
encased in plastic. The combs are designed to<br />
open or close under the torque effect of their rotational<br />
speed on the drive shaft. The greater the torque,<br />
the more the distortion.<br />
The TorqSense unit emits a low powered radio frequency<br />
signal towards the combs, which reflect it<br />
back. The reflected signal comes back at a changed<br />
frequency, the change being proportional to the distortion<br />
of the combs, and thus to the torque in the<br />
drive shaft.<br />
The physical phenomenon which deforms the<br />
combs is called the Surface Affect Wave (SAW), a<br />
property first noted in 1885 by gentleman-scientist<br />
Lord John William Strutt Rayleigh. He postulated<br />
many possible used for SAWs, but was unable<br />
to realise practical use for any of his theories. It was<br />
not until the 1920s that they were shown to be generated<br />
by the moving edges of earthquakes and avalanches,<br />
the recording of which using low frequency<br />
vibration monitors formed the basis of modern<br />
seismology and volcanology.<br />
By mid century scientists were creating SAWs in laboratories<br />
and developing new ideas for their use. As<br />
the century closed Sensor Technology Ltd were using<br />
the phenomenon to develop a new method of<br />
torque monitoring, the non-contact nature of which<br />
promised to be very attractive to working engineers.<br />
Testing pumps<br />
Charles Austen Pumps (CAP) has recently upgraded<br />
its test facilities with Surface Acoustic Wave (SAW)<br />
equipment from Sensor Technology. Charles Austen<br />
Pumps manufactures pumps individually designed<br />
to meet specific customer requirements that cannot<br />
be satisfied by off-the-shelf units. Much of its<br />
work comes down to optimising drive dynamics to<br />
produce the desired characteristics, be it a smooth<br />
flow in a critical medical situation, ultra low noise<br />
for pumps in home and office installations, or the<br />
guaranteed extra long life of pump in inaccessible<br />
locations.<br />
The cyclic nature typical in many pumps’ operation<br />
tends to induce torsional oscillations in the drive<br />
shaft, which can have a significant adverse effect
on performance if unchecked. CAP has recently built<br />
a new test station based on Sensor Technology’s SAW<br />
sensors, and it is proving it’s worth time and time<br />
again. Advantages of SAW techniques include a broader<br />
signal bandwidth than other analogue based technologies<br />
and elimination of electronic interference.<br />
As CAP found, it often also proves far lower<br />
cost, simpler to use, is more reliable and has a wider<br />
operating range than contact alternatives.<br />
Currying flavour<br />
Real time process control for food manufacture involves<br />
characterising the flow and mixability of highly<br />
non-Newtonian fluids. TorqSense transducers<br />
monitoring the constantly changing flow characteristics<br />
of materials as diverse as tomato ketchup,<br />
chocolate, pasta sauce and chicken tikka massala<br />
as they are mixed.<br />
Many manufactured food is presented in a sauce<br />
or as what physicists could describe as a neo-liquid<br />
and can be produced in a process-type environment.<br />
But to date real time control has been virtually<br />
impossible due to the non-uniform nature of the<br />
food, which may contain particulates, fibres, vegetables,<br />
meat, nuts, raisins, biscuits etc.<br />
To achieve real time control the TorqSense has to<br />
be able to detect the changes with sufficient sensitivity,<br />
yet be robust enough for regular washdowns<br />
and general industrial abuse. Of course it must<br />

not compromise hygiene standards and regimes either.<br />
The device has been found to meet all these<br />
requirements and is being used in by a number of<br />
food processors.<br />
Often the key requirement is to mix sufficiently to<br />
achieve a uniform dish, but not to waste time and<br />
energy by over-mixing. This can be done by monitoring<br />
the torque on the mixer’s shaft, as it will move<br />
to a steady state (within the characteristics of the<br />
given recipe) once fluid uniformity is achieved.<br />
Mixing<br />
A TorqSense is helping analyse recipes’ mixing<br />
properties in a project that could slash development<br />
costs in the food and plastics industry and help nanotechnology<br />
advance in the pharmaceuticals world.<br />
Research and development is being carried out at<br />
the University of Bradford to develop a miniature<br />
mixer (5-25 grams batch) that incorporates a set of<br />
integral instruments to monitor the properties of materials<br />
as they are being mixed. The instruments work<br />
in real time during the mixing process and their output<br />
is captured to a PC for analysis. Software is being<br />
written so that the analysis can be performed<br />
simultaneously with the mixing and perhaps even<br />
used to interactively control the mixer itself.<br />
One of the key parameters to be measured is the<br />
torque of the mixing element, as this will become<br />

constant once mixing is complete. This is measured<br />
by a TorqSense non-contact sensor that offers the<br />
development team the great advantage of not requiring<br />
complex and delicate slip rings, making the<br />
mixer easier to build (and rebuild between trials) and<br />
far more robust in operation.<br />
The Mini Mixer development and validation is the<br />
result of a three year EPSRC sponsored programme<br />
of research. The results of this research are expected<br />
to have a major impact on formulation of<br />
viscous mixes and scale-up of extruders. Traditionally<br />
recipes for formulating say specific coloured plastics<br />
for consumer products are developed in 25 to<br />
50kg batches, mixed in an industrial scale twin screw<br />
compounder. Several batches may be required before<br />
the recipe is finalised, so the cost and time involved<br />
can be considerable.<br />
Clearly the development of a smaller mixer is advantageous,<br />
but the laboratory device must be<br />
able to duplicate mixing in the larger scale and guide<br />
design and operation of large machines and that is<br />
what the research programme has achieved. The fact<br />
that the technology will transfer to the plastic industry<br />
and other soft solid sectors means it is likely<br />
to rapidly recoup development costs.<br />

Compressed tablets are still the<br />
most popular dosage form for<br />
pharmaceuticals. Over 75% of<br />
pharmaceutical products are sold in<br />
solid dosage form. Strong growth is<br />
predicted for compressed tablets<br />
due to the nutraceuticals market,<br />
especially in the USA.<br />
Tablet Production & Handling<br />
with Vacuum Technologies<br />
The potential for growth in tablet manufacturing is<br />
high. However, several challenges and trends are<br />
threatening the profit potential. Today, pharmaceutical<br />
manufacturers are challenged to evolve their<br />
production processes in order to survive and excel<br />
in an increasingly competitive industry. While<br />
product quality has always been of paramount<br />
importance, strenuous economic times and continually<br />
inflating drug prices are heightening consumer<br />
demand for lower-priced prescriptions. Tablet manufacturers<br />
are more than ever seeking new ways<br />
to automate their lines to speed and streamline production,<br />
and vacuum conveying technologies are<br />
providing an answer.<br />
By automating the conveying process, vacuum<br />
technologies can improve productivity and enhance<br />
quality. In addition, selecting a vacuum<br />
technology that is maintenance-free and energy-efficient<br />
can provide further benefits to tablet manufacturers.<br />
These benefits allow companies to cut<br />
costs and meet challenging consumer demands for<br />
quality pharmaceuticals and lower prices.<br />
Offering a safer environment<br />
In general, reducing manual labor through automated<br />
vacuum conveying can improve working conditions<br />
by reducing heavy lifting. In addition, American<br />
manufacturers must abide by Safety, Health<br />
and Environment (SHE) regulations enforced by the<br />
US Department of Occupational Safety & Health Administration.<br />
In Europe, the European Foundation<br />
for the Improvement of Living and Working conditions<br />
(EUROFOUNDA) oversees the improvement<br />
of industrial working conditions.<br />
Heat, dust and noise are all pollutants in the<br />
working environment that detract from worker safety<br />
and the stringent sanitation demands for pharmaceutical<br />
and chemical production. Tablet manufacturers<br />
can greatly reduce manual labor and<br />
diminish exposure to environmental irritants with<br />
the installation of a vacuum conveying solution<br />
that moves dry powder products through dedicated<br />
pipe systems. These systems fully contain<br />
the powders to minimize dust and also generate<br />
less heat.<br />
To ensure the highest standard of worker safety, the<br />
conveyors should also have few moving parts,<br />
and be easily assembled and disassembled to reduce<br />
worker strain.<br />
In one example of the benefits of vacuum conveying<br />
technology, Surepharm Services Ltd, a UK contract<br />
manufacturer specializing in tablet production,<br />
improved its working environment by reducing<br />
the amount of heavy lifting and manual labor performed<br />
by its employees. The company replaced<br />
its manual loading operation with three C-Series<br />
vacuum conveyors to transfer powder products<br />
to blending and tableting machinery. As a result,<br />
the company saved up to 30 hours of labor per week<br />
and reduced dust significantly. Additionally, the lightweight<br />
conveying equipment quickened the cleaning<br />
process by reducing the physical demand on<br />
the workers.<br />
Increasing uptime<br />
Given the 24/7 production runs in pharmaceutical<br />
manufacturing, automation technologies must be<br />
highly reliably. In today’s competitive pharmaceutical<br />
industry, there is simply no time for line<br />
stoppages or ongoing maintenance. Additionally,<br />
changeover can add significant costs and downtime<br />
to the production process. A vacuum conveyor<br />
must easily facilitate changeover or risk negating<br />
the gains realized through automation.<br />
Simple solutions can effectively combat the erosion<br />
of productivity caused by line stoppages,<br />
maintenance or changeover. Vacuum technologies<br />
with few moving parts are not only safer; they are<br />
maintenance-free and can reduce downtime. Conveyors<br />
that are easily handled by workers are<br />
more quickly assembled and disassembled, reducing<br />
the time it takes for equipment adjustments<br />
between batches and during cleanings.<br />
Machines containing fewer components also help<br />
minimize part mix-ups and help to prevent line stoppages.<br />
In one instance, Rottendorf Pharma, one of Germany’s<br />
leading contract manufacturers of solid dosage<br />
form drugs, replaced its traditional vacuum conveying<br />
machines with C2100-64 compact compressedair<br />
conveyors. The PIAB conveyors were lighter in<br />
weight and contained fewer parts. This made them<br />
easier and faster for workers to assemble and disassemble.<br />
As a result, the company reduced cleaning<br />
time from 7,200 hours to 6,600 hours yearly.<br />
The hours saved from cleaning were recycled back<br />
into manufacturing time and Rottendorf has improved<br />
productivity by 15 million tablets since the installation.<br />
Cost-effective, easy cleaning<br />
In addition to aiming to reduce changeover time,<br />
tablet manufacturers must also prevent cross-contamination<br />
of the product. A vacuum conveyor<br />
that is easily disassembled for quick clean-up is a<br />
cost-efficient way of averting cross contamination.<br />
In Rottendorf’s example, the light-weight<br />
conveyors that replaced its older equipment offered
a way to quicken the cleaning process and maximize<br />
uptime.<br />
Clean-in-place systems are effective but costly<br />
solutions to meeting strict FDA regulations on<br />
sanitary conditions. Additionally, the systems can<br />
add unnecessary bulk to existing equipment.<br />
Energy-saving solutions<br />
As energy costs soar, the reduction of energy usage<br />
is a strategic step to trim expenses from pharmaceutical<br />
manufacturing operations. In addition,<br />
reducing energy consumption is good for sustainability<br />
efforts. However, in terms of energy consumption,<br />
not all vacuum solutions are created equal.<br />
Conveying systems powered by decentralized<br />
vacuum technologies are more energy-efficient than<br />
their centralized counterparts. While a centralized<br />
vacuum system puts more distance between<br />
the source of the power and the point of use, a decentralized<br />
vacuum system uses multistage ejector<br />
technology to apply the vacuum where needed.<br />
This way, no additional energy is expended to<br />
compensate for the extra distance.<br />
Optimizing automation<br />
Automating the tablet-handling process affords many<br />
advantages and conveniences to pharmaceutical<br />
manufacturers, including increased productivity and<br />
reduced staff injury. However, poorly designed automated<br />
conveying systems can cause segregation<br />
and tablet breakage. Simple precautions can be taken<br />
to avoid incurring the costs of product waste as<br />
a result of either event.<br />
Preventing Segregation<br />
Particle separation prior to tablet compression,<br />
known as segregation, can threaten the integrity<br />
of drug dosages and jeopardize the uniformity of<br />
a batch. Segregation can occur during tablet production<br />
as a result of gravity and particle characteristics<br />
as well as due to external factors such as<br />
air flow and vibration.<br />
May 2009 33<br />
When implementing vacuum conveying, segregation<br />
risk can be significantly reduced by handling<br />
the material at a controlled speed to ensure that<br />
the materials stay blended.<br />
Preventing Tablet Breakage<br />
Tablets can also break due to exposure to friction<br />
and shock during or after the manufacturing<br />
process. A broken tablet is susceptible to contamination,<br />
rendering it useless. As a result, product<br />
waste can accumulate and cause production<br />
delays.<br />
To prevent breakage, tablet manufacturers can<br />
employ an accommodating vacuum conveying<br />
system. To start, the conveying system should<br />
have an adaptable feed rate to enable the system<br />
to be sped up or slowed depending on the size or<br />
volume of the tablets being handled.<br />
Also, the vacuum conveyor’s tubing and piping specifications<br />
along with couplings can be specifically<br />
designed to reduce speed and avoid product damage.<br />
The tubing and piping should have soft curves<br />
to avoid tablet breakage.<br />
Conclusion<br />
Vacuum automation technologies can play a key<br />
roll in streamlining tablet production. By taking the<br />
right precautions in installing a reliable, efficient<br />
vacuum conveying system, manufacturers can increase<br />
their productivity, reduce energy usage<br />
and improve their work environments. As companies<br />
harness vacuum technology to advance tablet<br />
production, more efficient conveying systems will<br />
translate into cost savings, helping tablet manufacturers<br />
stay competitive by enabling them to produce<br />
more affordable prescriptions.<br />

Godiva Chocolatier in Brussels,<br />
Belgium meet the highest quality<br />
standards with the installation of<br />
Self-Cleaning Filters and Compact<br />
Sieves, delivering maximum<br />
customer satisfaction everytime.<br />
Filters and Sieves for the<br />
Highest Quality Chocolate<br />
Godiva Chocolatier was founded 80 years ago<br />
in Brussels, Belgium and supplies its range of<br />
high quality "luxury" chocolates in over 80<br />
countries. Using only the finest chocolate and<br />
highest quality ingredients, Godiva chocolates<br />
are found in some of the most prestigious<br />
stores around the world, from Wanamaker's in<br />
Philadelphia, Pennsylvania to Nihonbashi Mitsukoshi<br />
Department Store in central Tokyo.<br />
Godiva uses both enrobing and shell moulding<br />
processes to manufacture the various sizes and<br />
shapes of chocolates, the latter being extensively<br />
used in Europe. As with many chocolate<br />
processes, foil is commonly used to wrap chocolate<br />
because of its decorative/luxury appearance<br />
and ease of wrapping varying shapes. However,<br />
this complicates rework processes, since<br />
the foil must be removed beforehand and as a<br />
result it is not uncommon for pieces of foil to<br />
contaminate the chocolate.<br />
To prevent this or any other foreign body contamination<br />
from entering the moulding process,<br />
Godiva has relied upon two large sieving units<br />
installed just before the chocolate depositors,<br />
which is the last stage of the process before chocolate<br />
is poured into the moulds. Although they<br />
have been reasonably effective, metal detectors<br />
would frequently alarm due to small fragments<br />
passing through the units causing costly rework.<br />
With the popularity of their chocolate increasing<br />
and with growing demand, Godiva recognized<br />
the need to review its process with the aim of<br />
gaining zero tolerance on contamination while<br />
improving production efficiency.<br />
At the early stages of the project, Godiva identified<br />
two areas where foreign bodies could<br />
enter the chocolate. Firstly, from the rework<br />
chocolate as it is returned to the storage tanks<br />
where it is mixed with virgin chocolate. Secondly,<br />
due to the nature of chocolate processing, contamination<br />
can be introduced due to large<br />
amounts of pipework and pumps being used to<br />
transport chocolate throughout the process.<br />
As a starting point, Godiva made contact with<br />
their chocolate supplier since every batch of virgin<br />
chocolate entering the Godiva plant is certified<br />
as contamination free. This resulted in a<br />
visit to one of the plants to learn how it was<br />
achieved. The systems used were fully enclosed<br />
self-cleaning filtration units supplied by Russell<br />
Finex. Peter Van Ingelghem, Engineering and Maintenance<br />
Manager of Godiva explains, “As soon<br />
as we saw the installation it was clear that<br />
this was the solution we had been looking for.”<br />
He added “With these systems installed there<br />
have been no reports of contaminated chocolate<br />
being delivered to our factory”.<br />
Without hesitation, Godiva made contact with<br />
the Russell Finex sales office in Mechelen, Belgium<br />
to discuss the project in more detail.<br />
Consequently, an in-depth risk assessment of the<br />
process was developed and, combined with<br />
Godiva’s research and Russell Finex’s experience,<br />
a design was finalised meeting all their objectives.<br />
The chosen solution utilised a combination of<br />
both liquid filtration units and round vibratory<br />
sieves covering two critical control points within<br />
the system. This provided Godiva complete<br />
control on contamination while increasing production<br />
flexibility required to meet market demands.<br />
The liquid filters installed were Russell Eco<br />
Self-Cleaning Filters, one after each storage<br />
tank. These would remove any contaminant<br />
from within the tanks that could have been<br />
introduced through rework. The units were selected<br />
due to their high flow rates and innovative<br />
self-cleaning design meaning operator involvement<br />
is kept to a minimum.<br />
The second control point was just before the depositors.<br />
A bank of Russell Compact Sieves replaced<br />
the two existing sieving units, working<br />
in tandem with the filters. “The Compact 400<br />
sieves were chosen as they fitted neatly into our
existing process without losing the cleanability<br />
of the depositors” states Van Ingelghem.<br />
The installation provided Godiva with a process<br />
that ensured contamination of foreign bodies<br />
was effectively eliminated. “Having a global recall<br />
is something that we are unable to quantify<br />
in terms of costs. However, with the new Russell<br />
systems in place we have complete peace<br />
of mind that our product is being supplied to the<br />
highest standards.” Van Ingelghem concludes;<br />
“In fact it has actually made our metal detectors<br />
virtually redundant since we rarely ever hear<br />
them activated”.<br />
The new installation has given Godiva complete<br />
traceability back to any contamination<br />
source. This has improved maintenance procedures<br />
whilst increasing efficiencies in the<br />
<br />
<br />
<br />
<br />

<br />
<br />

rework processes. Moving forward, Godiva<br />
has recognised the support that Russell Finex<br />
provided throughout the project whilst also<br />
offering a customer care support system that<br />
ensures a fast response to any maintenance<br />
requirements. This was particularly evident at<br />
the early stages when time was spent trying<br />
to select the optimum mesh sizes for the<br />
equipment.<br />
For over 70 years Russell Finex has manufactured<br />
and supplied filters, sieves and separators to improve<br />
product quality, enhance productivity,<br />
safeguard worker health, and ensure liquids<br />
and powders are contamination-free. Throughout<br />
the world, Russell Finex serve a variety of<br />
industries with applications including food,<br />
pharmaceuticals, chemicals, adhesives,<br />
plastisols, paint, coatings, metal powders and<br />
ceramics.<br />

The Longwatch Video Surveillance<br />
System now has an interface to Flir’s<br />
A-Series Thermal Imaging cameras,<br />
so that thermal images can be<br />
viewed on standard HMI/SCADA<br />
software, such as Wonderware<br />
InTouch or GE Fanuc iFix.<br />
Video Surveillance Software<br />
Integrates Thermal Imaging<br />
The capability to interface the Video Surveillance<br />
System with Thermal Imaging cameras expands<br />
process monitoring, maintenance and process<br />
diagnostics, because the thermal images allow<br />
operators to see product/utility leaks, “hot<br />
spots” in a process, imperfections in finished goods,<br />
and other anomalies. Infrared imaging can also<br />
be used for intrusion monitoring.<br />
Thermal imaging has been used to analyze<br />
processes and for security purposes for years, but<br />
such systems typically have been specialized,<br />
stand-alone or handheld systems. Now, Longwatch<br />
enables real-time thermal images to be<br />
displayed on HMI screens in the control room,<br />
integrated with process displays, so operators<br />
can see what is happening in a process or on an<br />
assembly line. Thermal images can be displayed<br />
side by side with video images on the same<br />
screen, for a complete picture of the process.<br />
The Flir thermal cameras connect to Longwatch<br />
Video Engine software, installed at strategic<br />
sites in the plant, next to process equipment,<br />
and along automation assembly lines. The<br />
video engine continuously records images from<br />
multiple thermal and standard video cameras<br />
onto a local disk for up to 30 days, and sends<br />
“video clips” over the plant network to the<br />
Longwatch Video Control Center (VCC) in the<br />
plant’s control room. The VCC then sends the<br />
clips to HMI/SCADA software, a cellphone or PDA,<br />
and stores them in a Video Historian. Clips can<br />
be sent on a regular scheduled basis, on com-<br />
mand from the HMI/SCADA system, when a<br />
process or assembly step occurs, or in real<br />
time when an alarm occurs. The Longwatch<br />
system also enables cameras to be located in<br />
far remote regions, communicating back to<br />
the central control room over a variety of lowspeed<br />
or high-speed networks.<br />
The thermal camera and the Longwatch software<br />
at the remote site can be configured to alarm when<br />
pre-defined temperature conditions are detected,<br />
such as if a steam leak occurs or a process<br />
becomes too hot or too cold, or if an unexpected<br />
image appears, such as an intruder. The system<br />
can retrieve thermal images from before the<br />
incident occurs—such as 30 seconds before the<br />
alarm—and immediately send a video clip to<br />
the operator when the alarm occurs. Longwatch<br />
creates a “video sequence of events recorder.”<br />
The operator can switch to a live video feed<br />
and monitor the process from the control room.<br />
If more data is needed for a detailed analysis of<br />
the problem, all or part of the Longwatch system’s<br />
video history can be retrieved from the Longwatch<br />
Video Engine in high-resolution format, downloaded<br />
to a thumb drive or DVR, and viewed on a PC.<br />
The Video Historian enables users to acquire and<br />
store video clips linked with process and manufacturing<br />
variables such as time of day, camera<br />
number, batch step, machine ID and other<br />
control system tags. This gives users the ability<br />
to store hourly, daily, or weekly thermographs<br />
of process components to benchmark patterns<br />
and changes over time. It also allows thermal video<br />
clips to be stored for each step of a process, to<br />
document that steps were completed successfully<br />
or for quality control purposes.<br />
The Video Historian allows multiple images to<br />
be displayed at the same time, so engineers can<br />
compare processes side by side. Process managers<br />
may find problems they did not know even<br />
existed and would not have found in the past<br />
without thermal imaging.<br />
Having the ability to see imperfections in a<br />
process is not the only benefit. Thermal imaging<br />
also allows users to see unnecessary usage of equipment,<br />
warning signs that equipment is on the way<br />
out, and gives managers plenty of warning of pending<br />
problems, allowing them to make informed<br />
decisions on how to proceed in certain situations.<br />

GRAVIMETRIC BLENDERS<br />
for up to 7 components and up to 3,000kg/hr<br />
The loss in weight gravimetric<br />
blenders provide<br />
a dosing solution for<br />
blending and extrusion<br />
control for up to 7 components<br />
and up to<br />
3,000kg/hr. They provide<br />
continuous throughput<br />
measurement, and maintain<br />
the extruder throughput<br />
at the desired level,<br />
i.e. Kg/hr control. Haul off<br />
speed measurement can<br />
be added to ensure that the weight per length<br />
is controlled to the desired specification (yield<br />
control). This ensures that the product being<br />
produced is maintained at the desired thickness<br />
without operator intervention. The user-friendly<br />
touch screen control panel provides intuitive<br />
text prompts, the operator can view material<br />
weights and kg/h throughput, and alarm incidents<br />
which are time and date stamped. The electronics<br />
design allows for rapid weight loss measurement<br />
allowing the blender to react to any<br />
change in line speed or screw speed. The blockage/stall<br />
feature will detect a stalled screw or<br />
material blockage while an encoder will provide<br />
instantaneous dosing screw speed data.<br />

PRESSURE TRANSDUCER<br />
differential, scalable measurement range<br />
The P 26 differential<br />
pressure transducer<br />
meets the high demands<br />
of applications<br />
like clean room monitoring<br />
and offers the<br />
ability to monitor sterile<br />
environments in the packaging machines for<br />
such industries as foods and pharmaceuticals.<br />
Measurement ranges between 100Pa and<br />
100kPa are freely scalable from 10 to 100%, and<br />
provide the option of switching to other units<br />
of measurement like mmH2O, mmHg, etc.<br />
Cyclical self-calibration of the zero point ensures<br />
a high level of measurement stability. Two<br />
cutoff points are available that can be set<br />
freely along the entire measurement range;<br />
these allow the user to connect visual or audible<br />
alarms that would be triggered any time values<br />
fall above or below limits. All measurement<br />
values can be read on an optional graphic<br />
LCD. The instrument can communicate with a<br />
master control unit via an RS 232 interface and<br />
can be mounted either on a wall or on top-hat<br />
rails. A hand-held unit can be used as a configurator<br />
for the one-time calibration when using<br />
more than one of the affordable P 26 pressure<br />
transducer without a display.<br />

FLOW CONTROLLER<br />
integrates sensor, electronics and valve<br />
The LiquidFlow Controller<br />
integrates sensor, control<br />
electronics and proportional<br />
valves in a single<br />
compact device making it<br />
suitable for applications<br />
requiring the fully-automatic<br />
metered dosing of<br />
small amounts of liquids.<br />
It is designed for the dynamic<br />
control or metering of liquids such as<br />
deionised or demineralised water, methanol<br />
or low-viscosity oils. The controller offers measurement<br />
and dosage of liquids with a nominal<br />
flow rate of 0.6 to 36 l/h and a span of 1:10.<br />
Thanks to its compact design, the controller can<br />
be installed in difficult locations, such as directly<br />
behind angled piping. The device is available<br />
in a IP65 version for rough environments. The<br />
integration of sensor, control electronics and actuator<br />
makes it no longer necessary to design<br />
complex individual components, and avoids<br />
interface-related communication difficulties.<br />
The digital controller offers flow-rate measurements<br />
without moving parts inside the<br />
medium flow. The Integrated prefilter is replaceable.<br />
The interfaces include analogue/digital<br />
via field bus or RS232/RS485.<br />

LONGLIVED PUMPS<br />
with electronic monitoring module<br />
The company now offers<br />
additional protection<br />
for the<br />
longevity of its<br />
pumps. The Allready<br />
Box is an electronic<br />
module that continuously<br />
monitors a<br />
pump’s operational<br />
state. In the event of<br />
operational deviations<br />
or disturbances, it immediately<br />
emits a warning. In urgent cases it<br />
triggers an alarm and even has the ability to<br />
switch the pump off in hazardous conditions and<br />
switch over to a secondary unit. This monitoring<br />
device can be mounted on new pumps or<br />
retrofitted to existing pumps at any time. One<br />
sensor measures the liquid level in a leak can<br />
below the shaft seal. A second sensor monitors<br />
the temperature at the bearing bracket. If one<br />
of the values reaches a critical value the device<br />
will trigger an optical warning. If the level<br />
or temperature continues to climb and exceeds<br />
a second limit value, it will trigger an alarm. Signals<br />
can also be forwarded to external displays<br />
and integrated into the customer’s structures,<br />
such as an existing control center.<br />

SUPER SEAL AND CUP SEAL<br />
minimise the risks of glass inclusion<br />
Wherever high-speed bottling is required, such as with beer,<br />
wines, ciders, water or carbonated drinks, in case of bottle<br />
breakages there is always the risk of glass inclusion in<br />
seals and centering cups. The Super Seal and new cup seal manufactured from polyurethane<br />
with a patented auto-decontamination system minimises strongly this risk. The choice<br />
of materials was crucial in maximising safety and improving efficiency. These seals<br />
are FDAapproved and have an increased lifespan which is on average twice as long<br />
as the one of comparable cups and seals manufactured from rubber based materials.<br />
They are coloured coded so that it becomes very easy for users and maintenance<br />
staff to identify the right cup or seal for the right bottle filler. Furthermore they<br />
offer superior changeability, wearability and sanitation and they help on saving costs.<br />

LIQUID TURBINE FLOW METER<br />
for mobile fuel operations<br />
The portable Daniel Series<br />
500 Liquid Turbine Flow Meter<br />
serves the need for highly<br />
accurate flow measurement<br />
in road tanker off-loading<br />
and can be used as a<br />
check meter at loading points<br />
in distribution terminals. It<br />
can also be mounted to loading<br />
arms to monitor the performance<br />
of other meters<br />
during loading operations<br />
in distribution terminals,<br />
and is easily removed when the verification is<br />

The industrial-grade<br />
wireless LAN access<br />
points feature a wireless<br />
interface in compliance<br />
with IEEE802.11n (draft<br />
2.0). The new wireless<br />
standard permits similar<br />
transfer rates as<br />
achieved by a Fast Ethernet<br />
cable. MiMo (multiple<br />
input, multiple<br />
output) send and receive<br />
technology provides<br />
significantly higher reach, reliability and<br />
stability of wireless transmissions both in the<br />
2.4GHz and in the 5GHz frequency range. Moreover,<br />
MiMo is particularly suitable for applications<br />
where typical industrial interferences<br />
must be expected, such as reflexions. WLAN devices<br />
equipped with wireless interfaces according<br />
to older IEEE802.11a/b/g/h standards<br />
also benefit from the greater reach of the new<br />
access points. The IWLAN access points are offered<br />
