Wilden, part of PSG, a Dover company, has released its new PS20 102 mm (4-in.) 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.
