Wilden®, part of PSG®, a Dover company and a worldwide leader in air-operated double-diaphragm (AODD) pump technology, is pleased to announce the availability of its PS1 Original™ 13 mm (½”) clamped 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.
The Wilden 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.
The footprint of the PS1 Original matches that of the Wilden PX1 Original, which enables direct replacement of a PX1 Original with no repiping necessary. With less components (no dial) and 7% more efficient than the PX1 Original, the backward capability of the PS1 Original makes it an easy, cost-effective way to enhance and upgrade existing pump performance. PS1 Original pumps are shear sensitive and intrinsically safe with self-priming and dry-run capabilities, and offer the longest mean time between repair (MTBR), superior anti-freezing and increased on/off reliability.
The Wilden PS1 Original has an aluminum center block and is available with an aluminum, stainless steel or alloy C wetted-path material. Meeting CE and ATEX requirements, the pump features maximum discharge pressures to 8.6 bar (125 psig), maximum flow rates to 60.2 lpm (15.9 gpm), and maximum suction lifts to 5.9 m (19.3’) dry and 9.8 m (32.2’) wet. Diaphragms are available in Buna-N, EPDM, Polyurethane, PTFE, Saniflex™, Viton® and Wil-Flex™. Additionally, PS1 Original pumps will be available for compliance with FDA CFR 21.177 and 1935/2004/EC standards.
