ARO PD05P-ASS-SAA Pneumatic Double Diaphragm Pump

ARO PD05P-ASS-SAA is a 1/2" fluid-port AODD diaphragm pump in the Metallic Compact Series designed for reliable air‑operated fluid transfer. The center body is polypropylene with stainless steel fluid caps and manifold, while wetted parts use Santoprene for the diaphragm and balls and stainless steel seats for durability in chemical service. It offers 1/2" NPTF intake and discharge ports in a multiport configuration (with an air inlet of 1/4" NPT), enabling versatile piping arrangements. The unit delivers up to about 14.5 gpm (14.4 gpm at 100 psi) and handles up to 100 psi (6.8 bar) discharge pressure, with a maximum head around 15 ft and a maximum solid particulate capacity of 0.09 in. Self-priming operation and potable-system compatibility broaden its use in chemical transfer, washdown, and general liquid handling where corrosion resistance and portability matter. Exterior dimensions run roughly 10 in long by 6.7 in wide by 10.9 in tall, and it weighs about 14.6 lb, making it feasible for relocation across job sites. Manufactured in the USA as part of the PD05P family and featuring ATEX CE Ex11 2GD X compliance, the PD05P-ASS-SAA is a robust choice for demanding fluid-handling tasks that require high-volume delivery at moderate air pressure.
