Double Diaphragm Pump, 13 gpm Max. Flow, PTFE, Single Manifold Connection, 1/2 in

Offering high volume delivery even at low air pressure this ARO® double diaphragm pump features maximized flow rates with minimal pulsation and air consumption. This air-operated, double-diaphragm model utilizes a pressure differential in the air chambers to alternately create suction and a positive fluid pressure in the fluid chambers, and ball checks to help insure a positive fluid flow. Pump can provide reliable operation with innovative, lube-free differential valve both on the major air valve and Simulshift™ pilot valve for worry-free operation.
