cpp TRADE FAIR REVIEW Robust dry vacuum pump In-line chemical process pump The oil-free Varodry screw pump from Leybold guarantees the required operating pressure, a short cycle time, high system availability and robustness – especially in moist or dusty processes. Varodry is also easy to install and connect. Thanks to its compact design and reduction to the essential, the vacuum pump can be easily integrated into new or existing systems. Equipped with complete air Picture: Leybold cooling, the pump makes water cooling superfluous. The developers at Leybold were guided by the idea of using fewer, proven machine parts and components in their design. The Varodry convinces its users with low maintenance requirements, emission-free ventilation and minimal operating noise in average daily operation. Moreover, this pump is absolutely dry and clean, thus preventing oil and particle emissions or oil leaks as well as oil migrations in the vacuum chamber or into the products and processes. The pump series is offered in the two pumping speed classes VD 65 and VD 100. www.cpp-net.com Online search: cpp0318leybold Picture: CP Pumpen Designed to pump highly solidladen media, CP’s ILBTO is the ideal solution for the fluid’s handling within the high demanding production process. By using a frequency converter, the customer then has the required flexibility to gear the pump towards various conveying tasks and media characteristics. Hence, he is able to run up to ideal operating points. According to the customer’s requirements, a high-quality nickel alloy 2.4602/24610 has been chosen to use the pumps for multiple fluids. Those alloys are especially resistant to oxidising, reducing and compounding acids as well as other media. www.cpp-net.com Online search: cpp0318cppumpen Safety workstation for laboratories Space-saving 2-in-1 palletiser Picture: Weiss Pharmatechnik Weiss Pharmatechnik developed the Wibobarrier Lab Containment, a safety workstation with integrated laboratory device, in cooperation with the Excellence United partner Glatt. The intelligent technology of the safety workstation makes it possible to perform, with only one single Wibobarrier system several laboratory processes one after another, such as weighing, granulation, sifting, drying, mixing, pelletising and coating. Each laboratory process unit or combination of two process units by Glatt takes place on a mobile worktable, which can be moved flexibly into the Wibobarrier clean room area. To keep the cleaning effort as low as pos - sible, control of the process device takes place outside the system. Wibobarrier systems can be variably extended according to the OEB level and application and offer a multitude of combinations and configuration options. For example, two systems can be used simultaneously to further increase process efficiency. www.cpp-net.com Online search: cpp0318weiss Picture: Möllers Proven palletising technology combined with highcapacity stretch hood technology – this competence is bundled in the highly-efficient 2-in-1 series. Möllers presents this combined machine which meets greatest requirements regarding transport security and manages with modest space capacity. The low-level modular palletiser stacks packed goods both stably and securely in all desired pallet formats. The integrated automatic stretch hooder then wraps – with lowest possible film consumption and high efficiency. www.cpp-net.com Online search: cpp0318möllers 38 cpp 03-2018
Mixing in medium-viscous systems To improve the performance of reactors Ekato has developed the Varioblade, which is a flexible, modular impeller with an optimised split between axial and radial flow components by different shapes of the upper and lower impeller parts. Compared to standard frame or blade type impellers, the blend times – especially in the mid-viscous range – can be improved by up Picture: Ekato to 50 %. The Varioblade is not a close-wall-clearance system but operates in the centrer of reactors – typically with coils – where radial flow components are required. The positioning of the three elements – outer blade, inner blade and bottom anchor – can be varied. Therefore this impeller can handle different mixing task combinations with varying viscosities of up to 50,000 cP. As an example, the modular inner blade can be adjusted to achieve a high dispersion effect. This is a significant advantage for multi-phase applications such as gas-liquid or liquidliquid reactions. www.cpp-net.com Online search: cpp0318ekato OUR EXPERTISE IS YOUR BENEFIT! Short delivery time Made in G Germany ISO 90011 Intrinsically safe signal transmission The EtherCAT Terminals in the ELX series have been expanded from Beckhoff by the addition of analogue input terminals with Twinsafe SC (Single Channel) technology. These highly compact I/O terminals can be used to support applications in hazardous areas that require both intrinsically safe signal transmission and functional safety capabilities. The compact ELX series terminals, which are certified in compliance with the specifications of the Atec and IECEx standards, enable direct connection of intrinsically safe field devices through to zone 0/20 based on an integrated safety Picture: Beckhoff barrier. The new terminal designs extended by Twinsafe SC technology now also make it possible to achieve a safety level equivalent to PL d/Cat. 3 according to EN ISO 13849–1 or SIL 2 according to EN 62061. In this way, it is possible to use all process data existing in a system for safety technology too, such as to monitor the speed of fans in areas sensitive to explosion hazards, for example. The I/Os are available as 12 mm wide terminals with two or four analogue input channels for 0/4…20 mA, and for RTD resist ance sensors, thermocouples/mV and strain gauges. Furthermore, a single-channel terminal is available for the direct connection of intrinsically safe incremental encoders, which evaluates a diagnosticenabled Namur signal in accordance with IEC 60947–5–6. www.cpp-net.com Online search: cpp0318beckhoff Mini-Turbine Pumps High-quality standard units plus individual designs for water, solvent, acids, bases and more...
