PD20P-FPS-PTT ARO 2" Polypropylene Non-Metallic Expert Series Air Operated Double Diaphragm Pump
AROP/N PD20P-FPS-PTT ARO 2" Polypropylene Non-Metallic Expert Series Air Operated Double Diaphragm Pump
The ARO PD20P-FPS-PTT is a non-metallic Expert Series 2-inch air-operated double-diaphragm pump designed for dependable, high-volume fluid delivery even at low air pressure. Its polypropylene center body, fluid caps, and manifold with stainless steel hardware, combined with polypropylene seats, PTFE valve balls, and PTFE diaphragms with Santoprene® backup, provide a durable fluid-handling configuration for demanding industrial and process applications.
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 and serviceable air and fluid sections support dependable operation and convenient maintenance, 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. Maximum temperature limits are based on mechanical stress only, and certain chemicals can significantly reduce the maximum safe operating temperature.
