Clamped Metal AODD Pump
The air-operated double-diaphragm (AODD) pump is equipped with the company’s Pro-Flo Shift air-distribution system. That system incorporates an air control spool that automatically restricts the amount of air going into the pump during the latter part of each stroke. This eliminates overfilling of the air chamber and results in reduced energy consumption, says the manufacturer. 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 has maximum discharge pressures to 125 psig (8.6 bar), maximum flow rates to 15.9 gal/min (60.2 lpm), and maximum suction lifts to 19.3’ (5.9 m) dry and 32.2’ (9.8 m) wet.
