Wilden®, part of PSG®, a Dover company and a worldwide leader in air-operated double-diaphragm (AODD) pump technology, is pleased to announce the release of its new PS20 102 mm (4”) Original™ Metal AODD Pump equipped with the energy-efficient Pro-Flo® SHIFT Air Distribution System (ADS). This new high performance pump features the reliability and energy savings of the Pro-Flo SHIFT ADS while its clamped configuration allows for easier maintenance, diaphragm replacement and cleaning.
Wilden’s patent-pending Pro-Flo SHIFT ADS incorporates a unique Air Control Spool that automatically restricts the amount of air going into the pump during the latter part of each stroke, which eliminates over-filling of the air chamber and results in reduced energy consumption. By optimizing air consumption, the Pro-Flo SHIFT lowers energy and operating costs, achieving up to 60% savings over competitive AODD pump technologies.
The Wilden PS20 has a cast iron wetted path and is available with center block materials in aluminum, polypropylene or stainless steel. Meeting CE and ATEX requirements, the pump features maximum discharge pressures to 8.6 bar (125 psig), maximum flow rates to 1048 lpm (277 gpm), and maximum suction lifts to 4.4 m (14.4’) dry and 8.6 m (28.4’) wet. Diaphragms are available in Buna-N, EPDM, Geolast®, Neoprene, Polyurethane, PTFE, Saniflex™, Viton® and Wil-Flex™.
