Diaphragm Pumps

Balcrank Diaphragm Pumps feature a stall resistant design with modular air motor and fluid sections. Air operated double diaphragm pumps utilize a pressure differential in the air chambers to alternately create suction and positive fluid pressure in the fluid chambers, ball checks insure a positive flow of fluid.

NEWLY INTRODUCED: Balcrank has introduced their new patented technology CenterFlo pumps. They feature reversed air/fluid design compared to conventional diaphragm pumps. Fluid path fl ows through the center of the pump with the air motor to the outside allowing improved suction and performance, less air consumption with less pulsation throughout the
performance curve.

Balcrank is the answer to all your diaphragm pump needs!
