Single Head Diaphragm Vaccuum Pump

Diaphragm. Diaphragm Vacuum Pumps are dry pumps that operate using a pulsing motion that opens and closes valves to move air. This design eliminates the need for oil.Vacuum pumps are simply compressors that take in gas at a pressure lower than atmospheric pressure, compress it, and discharge the gas at atmospheric pressure. Since gas at low pressures has a large volume, vacuum pumps tend to be bulky.The number one diaphragm causes a press stroke moving liquid out of the pump. At the same time diaphragm number two is performing a suction stroke. The air behind diaphragm number two is being pushed out to the atmosphere causing atmospheric pressure to push the liquid to the suction side.
