Sandpiper S15B3PZPPAS000 1-1/2 in Polypropylene AODD Diaphragm Pump

The Sandpiper S15B3PZPPAS000 is a new, standard-duty 1-1/2 in (38 mm) air-operated double-diaphragm (AODD) pump manufactured by Warren Rupp, Inc. (an IDEX Corporation brand) and assembled in the USA. Decoding the part number: S = Sandpiper standard-duty, 15 = 1-1/2 in port size, B3 = bolted polypropylene fluid section construction, PZ = polypropylene pump body/manifold, PP = polypropylene diaphragms (PTFE-backed), AS = Acetal/Santoprene ball check valves, 000 = no options. The pump features an all-polypropylene wetted fluid section — including flanged manifolds, liquid chambers, and valve seats — making it highly resistant to a broad range of corrosive chemicals, acids, and solvents encountered in chemical processing, water treatment, and industrial transfer applications. The center section houses a black glass-filled polypropylene/acetal air distribution valve assembly (air valve P/N 476.253.000) and operates on compressed air up to a maximum of 100 PSI (7 BAR) as confirmed on the nameplate; no electricity is required, making it inherently safe for flammable or hazardous fluid handling. Port connections are flanged (ANSI flange pattern for 1-1/2 in), and the pump is self-priming and capable of running dry without damage, consistent with Sandpiper S15 series published performance data.
