OEM Diaphragm Air & Gas Pumps
OEM Diaphragm Liquid Pumps

Diaphragm pumps (also known as membrane pumps) work by positive displacement. These pumps use a motor to drive a connecting rod to oscillate an elastic membrane up and down to move air, gas, or liquid through a pumping action. On the downward stroke, the diaphragm sucks in the medium via the inlet valve and on the upward stroke, it forces the medium out via the outlet valve. The diaphragm hermetically seals the compression chamber from the drive mechanism.
