Principle of the Diaphragm Pump
An elastomer diaphragm (see illustration) is moved up and down by an eccentric. On the down-stroke it draws the air or gas being handled through the inlet valve. On the up-stroke the diaphragm forces the medium through the exhaust valve and out of the head. The compression chamber is hermetically sealed from the drive mechanism by the diaphragm. the pumps transfer, evacuate, and compress completely oil-free.
Features of Diaphragm Pumps
- uncontaminated transfer, no pollution of the media
- 100 % maintenance-free
- compact design
- smooth running
- easy installation
- with very few exceptions, the pumps can operate in any installed position
Liquid pumps have the following additional features:
- self-priming
- will operate dry
In addition to the above features, diaphragm pumps for gases have excellent gas tightness.
