Industrial PD05P-PPT-B Air Operated Diaphragm Pump

The ARO PD05P-PPT-B is a 1/2-inch, polypropylene-bodied air-operated double-diaphragm (AODD) pump designed for high-volume industrial fluid transfer. It uses a 1:1 diaphragm ratio and an unbalanced air valve to minimize stall, with self-priming operation and the ability to run dry under many conditions. ARO standard fittings include a 1/4-18 PTFE air inlet SAE short, and inlet/outlet ports commonly sized at 1/2 inch (with various NPTF or BSP configurations available by model). The pump delivers up to roughly 14.4 gallons per minute (about 54.5 L/min) and is engineered for non-metallic service, offering good chemical resistance while keeping weight in the 5–7 lb range across variants. In the PD05P family, representative models vary (for example XDS, XES, XKS, XLS, XPS) in weight and porting, but all share the same 1:1 AODD architecture and polypropylene construction. Typical applications include industrial fluid transfer, chemical processing, and general pump duties where a compact, lightweight AODD pump is advantageous, featuring easy maintenance and modular air motor and fluid sections for customization.
