A diaphragm pump (also known as a Membrane pump is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or viton diaphragm and suitable valves on either side of the diaphragm (check valve to pump a fluid.
Employing volumetric positive displacement where the prime mover of the diaphragm is electro-mechanical, working through a crank or geared motor drive, or purely mechanical. When the volume of a chamber is increased (the diaphragm moving up), the pressure decreases, and fluid is drawn into the chamber. When the chamber pressure later increases from decreased volume (the diaphragm moving down), the fluid previously drawn in is forced out. Finally, the diaphragm moving up once again draws fluid into the chamber, completing the cycle.
Diaphragm pump characteristics:
-
Have good suction lift characteristics, some are low pressure pumps with low flow rates; others are capable of higher flow rates, dependent on the effective working diameter of the diaphragm and its stroke length.
-
Have good self priming capabilities.
