How do Diaphragm Compressors Work?
What is a diaphragm compressor? Diaphragm compressors move (and compress) gas using a set of three, flexible diaphragm membranes. Gas enters the compressor’s process head from an external tank or process on its down-stroke. On the up-stroke, the diaphragms flex, reducing the area inside the chamber, pushing the gas out of the compressor (and on to the process/application). The oscillating movement of the diaphragms is driven by a reciprocating piston and crankshaft mechanism. Only the process diaphragm and the compressor’s process head come in contact with the gas. This is important because the diaphragms prevent hydraulic fluid (or oil from...
