air for the drive source is imperative. A maximum operating pressure
of 8 bar is required to operate the pumps.
Automatic pulsation dampers and suction and discharge hose connectors
are available as accessories and likewise stroke counters for
accurate dosing.
The reliable functioning of I&C systems can be impaired by the following
influences:
– Method of operation, i.e. the ability to meet the requirements that
are essential for the intended use of the I&C systems (identification
of overfilling, stopping an incipient explosion, turning on ventilation)
– The process error tolerance time
– External events such as overvoltage, power loss
– Errors with a common cause, such as contaminated compressed air,
defective insulation

Risk reduction in explosion zones:
Read the manual! Reliable pump
moni toring keeps company management
out of prison
Pump monitoring in industrial processes is far more than just a safety
measure for the pump unit. Aside from preventive maintenance and
the recording of operating data, ignition source monitoring has become
significantly more important in recent years – especially in explosion
zones. Precise risk classification is crucial for explosion prevention.
Reliable pump monitoring is essential to ensure smooth
processes and therefore operating efficiency.
TÜV safety experts are familiar with this scenario: Pumps that lack adequate
stability can quickly run hot. This heat can lead to an explosion
with devastating damage in production. The company may be liable
for part of the damage if the liability insurance provider can prove negligence
on the company’s part. This makes unprotected pump units a
high operational risk. Beyond that, the responsible managers commit
a crime if they fail to comply with legal requirements. In short, reliable
pump monitoring keeps company management out of prison!

Safety in the production process is a top priority for companies
Safety in the production process is a top priority for companies.
Numerous interrelated standards and directives are therefore in place.
Consistent application is essential for all of them, for example, the Industrial
Safety Directive (BetrSichV) and the Technical Guideline for the
Handling of Hazardous Materials (TRGS) 725.
What may appear simple and logical at first glance quickly turns
out to be complex after entering the jungle of standards, guidelines,
directives, technical rules and manufacturer recommendations that
need to be observed for the monitoring of ignition sources.
The IEC/EN 60079-xx standards on the topic of explosion protection,
DIN EN 50495 (Safety devices required for the safe functioning of
equipment with respect to explosion risks) and DIN EN 14597 (Temperature
control devices and temperature limiters for heat generating
systems) are all relevant for this topic. An examination of the DIN EN
14597 standard always comprises a complete measuring, control and
limiting system consisting of sensors, logic and actuating elements.
The following aspects, for example, are certified for the individual components:
Confusing jungle of standards and directives
Few manufacturers cover the entire safety chain for instrumentation
and control (I&C) with their products and solutions.
– Response characteristics of the sensor technology
– Reactions (modes of action) of the evaluation electronics
– Reliability/service life of the actuating elements
