Air Diaphragm

Air Diaphragm Positive Displacement Pumps. These positive displacement pumps use the reciprocating action of a flexible diaphragm to pump a fluid. Diaphragm pumps are defined by the manner in which the diaphragm is flexed. The air diaphragm pump has its diaphragm flexed by variations in air pressure. When the diaphragm moves up, the pressure in the chamber decreases, and fluid is drawn into the chamber. When the diaphragm moves down, the pressure increases and fluid is forced out of the chamber.
