Description

P/N PD20A-ACS-HAA-B ARO 2" Cast Iron Metallic Expert Series Air Operated Double Diaphragm Pump

The ARO PD20A-ACS-HAA-B is a metallic Expert Series 2-inch air-operated double-diaphragm pump designed for dependable, high-volume fluid delivery even at low air pressure. Its aluminum air motor section, cast-iron fluid caps and manifold with stainless-steel hardware, combined with Santoprene® diaphragms, Santoprene® check balls, and Hard 440 stainless-steel seats, provide a durable fluid-handling configuration. 

Built for reliable pneumatic operation, the Expert Series design incorporates ARO's patented SimulShift™ air valve technology to help avoid stalling and Quick Dump™ check valves that divert cold exhaust air away from ice-prone components to help reduce freezing and downtime. Its bolted construction supports secure fluid containment and convenient serviceability, making the pump well suited for fluid transfer, filling, recirculation, batching, and other industrial process applications.

Application suitability should be confirmed based on the specific fluid, concentration, temperature, viscosity, chemical compatibility, solids content, and operating conditions.
