ARO PD10P-BPS-PAA 1 In BSP Diaphragm Pump, Santoprene/PP
1 in EXP polypropylene AODD pump with BSP threads, Santoprene diaphragms and balls, PP seats.
This 1 in EXP pump uses BSP thread connections, polypropylene wetted parts and Santoprene diaphragms and balls on polypropylene seats.
For piping systems that use British Standard Pipe threads, the ARO PD10P-BPS-PAA offers a 1 in BSP connection on a non-metallic EXP body. The center section and every wetted part are polypropylene. Santoprene makes up the diaphragms and the balls, which seat on polypropylene. Fasteners are stainless steel.
Rated output is 53.0 gpm (200.6 lpm). The pump accepts up to 120 psi (8.3 bar) of inlet air and passes solids to 1/8 in.
Santoprene is a thermoplastic elastomer often picked as a general-purpose diaphragm material. Pairing it with polypropylene seats keeps the whole valve and chamber stack non-metallic. Because the ports are BSP, they will not mate directly with NPT fittings, so plan adapters if your site mixes thread standards. The model number code document explains each position of the part number when you need to compare builds.
