Diaphragm Pumps
The diaphragm is sealed with one side in the fluid to be pumped, and the other in air. The diaphragm is flexed, causing the volume of the pump chamber to increase and decrease. A pair of non-return check valves prevent reverse flow of the fluid.
Diaphragm pumps: have good suction lift characteristics, have good dry running characteristics, are low-shear pumps, can handle highly viscous liquids, cause a pulsating flow.
