ARO PD03P-APS-PAA 3/8 in. Non-Metallic AODD Pump
Compact Series 3/8 in. AODD pump with polypropylene center body and stainless fasteners; up to 10.6 gpm.
ARO's PD03P-APS-PAA is a compact 3/8 in. non-metallic double diaphragm pump with flow up to 10.6 gpm. Its parts list has 54 service items.
ARO's PD03P-APS-PAA fits a 3/8 in. double diaphragm pump into the small Compact Series footprint. Polypropylene forms the center body of this non-metallic build, and the fasteners are stainless steel. Maximum flow is 10.6 gpm, or 40.1 lpm, and the pump self-primes and handles fluids of varying viscosity while running on compressed air, even at low air pressure.
Air acting on one diaphragm pushes fluid out of its chamber while the opposite diaphragm draws new fluid in, and flat checks set the direction. When a downstream valve shuts, the pump holds line pressure and stops, then restarts as demand returns. Bolted construction helps keep the fluid side leak-free, and the modular layout makes teardown simpler.
