Pump Solutions Group (PSG), an operating company within Dover Corporation and a global leader of pumps, systems and related technologies, featured its Wilden brand’s new Pro-Flo SHIFT Air Distribution System (ADS) at Khimia 2013 in Moscow. The system, thanks to its revolutionary design, allows Wilden air-operated double-diaphragm (AODD) pumps to achieve up to 60 per cent savings in air consumption over all competitive AODD pump technologies, while providing more product yield per standard cubic foot per minute (SCFM).

The Pro-Flo SHIFT ADS is available for use in Wilden Advanced Series bolted and Original Series clamped AODD pumps, and its robust design makes it ideal for use in harsh operating environments and includes ATEX compliance for use in potentially explosive atmospheres. Wilden will also be displaying its Advanced Series AODD Pumps. Due to its bolted configuration, Wilden Advanced Series pumps ensure total product containment while the redesigned liquid path reduces internal friction to maximize output and efficiency.

Several other PSG brands showcased their products.

Almatec displayed its innovative AODD pumps, including its E-Series plastic AODD pumps that have been specifically designed to handle and transfer the most dangerous chemicals, including acids, solvents and caustics. E-Series pumps feature no mechanical seals or packing, eliminating a critical leak point. Rather, Almatec offers a unique stainless-steel containment ring that creates consistent high-torque compression all the way around the ring, pulling the components tightly together and eliminating a potential leak path. The E-Series is made from CNC machined solid block PTFE or PE, which allows the pumps to be used in the harshest environments handling the most dangerous chemicals. Other features include a pulsation dampener that ensures a consistent flow rate with minimum pulsation and vibration; as well as a barrier chamber system that prevents media from spilling into the atmosphere.

Mouvex featured its C-Series Eccentric Disc Pumps. Mouvex C-Series pumps safely handle the most dangerous chemicals thanks to its design that requires no magnets, no mechanical seals or packing. The seal-less design allows the C-Series to self-compensate for mechanical wear, giving the pumps the ability to maintain consistent flow rates over time. The seal-less design also ensures total product containment – a critical part of handling dangerous chemicals such as isocyanates, acids, solvents and caustics.

Other design features of the ATEX-rated C-Series are self-priming and line-stripping capabilities; low shear rate; high vacuum and compression effect; reduced maintenance, and clean-in-place (CIP)/sanitise-in-place (SIP) capabilities. Additionally, Mouvex recently announced the availability of the SLC4 and SLC8 models of its Seal-less Drive Eccentric Disc Pumps.

Blackmer displayed its System One centrifugal pumps, which have been designed for high-volume, severe-duty applications making them ideal for critical applications within the chemicals industry. Designed around the seal where 90 per cent of pump failures occur, the System One has a stiffer heavy-duty shaft and larger bearings resulting in the widest operational window off the Best Efficiency Point (BEP) than any standard process pump. This means that chemical processors can expect the System One to improve mean time between failures to reduce maintenance costs.
