ARO 666101-244-C Air Pneumatic Diaphragm Pump

ARO 666101-244-C is a 1-inch metallic, air-powered diaphragm pump from the PRO Series, built around an aluminum center body with stainless fluid caps and a single-manifold configuration. It features 1" NPTF ports for inlet and outlet and is driven by a 1/4" NPT air inlet. Wetted parts include an aluminum body, stainless fluid caps and manifold, 316 stainless seats, PTFE balls, and a PTFE/Santoprene diaphragm, with stainless hardware. The pump delivers up to 35 GPM (133 LPM) at up to 120 psi (8.3 bar) of air pressure, with a displacement of 0.16 gal (0.60 L) per cycle and a maximum suction lift of 20 ft. Weighing about 37 lb, it uses a single-inlet, single-outlet arrangement. This robust metal construction and the PTFE/Santoprene diaphragm combination support reliable liquid transfer in demanding industrial environments where durable, high-capacity pumping is required.
