The ARO air operated diaphragm pump is a double diaphragm pump with positive displacement that uses a 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. Air operated diaphragm pumps are designed for general use. They can easily pump from clean, light viscosity fluids to corrosive, abrasive medium viscosity fluids and can transfer large particles without damage. Due to their pneumatic motor, they could be used in potentially explosive areas. Air operated diaphragm pumps utilize a pressure differential in the air chambers to alternately create suction in the fluid chambers. Pump cycling will begin as air pressure is applied. Features Compact, rugged design allows for easy mobility Motor design delivers optimum air efficiency ARO's patented 'Unbalanced' air valve ensures no-stall operation Aluminum construction to withstand tough chemical applications Bolted construction for leak-free fluid handling Easy access to ball checks and fluid caps for maintenance and repairs Specifications Diaphragm pump Air operated 1 in. connection 1 -11-1/2 NPTF-1 air connection Positive displacement Solids handling: 1/8 in.
