Diaphragm pump is a pump that is designed with a positive displacement system. This pump works back and forth sucking and pushing water from the pump room. Diaphragm pumps use flexible membrane components that are used as transfer elements. This type of industrial pump transfers energy from the drive to the liquid through the drive shaft that moves back and forth to move the diaphragm, so that the suction and pressure alternates between the suction valve and the pump lid valve.
