ARO PRO Metallic Series 1 in. NPTF Aluminum Air Diaphragm Pump w/ Hytrel Diaphragms & Balls, Aluminum Seats 666100-1C9-C

The ARO air operated diaphragm pump is a double diaphragm pump with positive displacement that uses two sets of flexible membranes to pump fluids and a series of check valves to ensure fluid can only travel in one direction through the chamber. It can pump from clean, light viscosity fluids to corrosive, abrasive medium viscosity fluids and can transfer large particles without damage.
