Wilden's PS20 102 mm (4 in) metal AODD pump.

Wilden's PS20 102 mm (4 in) metal AODD Pump is equipped with the Pro-Flo Shift Air Distribution System (ADS) and its clamped configuration is designed for easier maintenance, diaphragm replacement and cleaning.

Wilden’s patent-pending Pro-Flo SHIFT ADS incorporates a 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 could lower energy and operating costs, achieving up to 60% savings over competitive AODD pump technologies.
