100% Oil-Free Operation

A drive in the diaphragm pump housing causes the connecting rod to oscillate and the diaphragm to move up and down. On the downward stroke, the diaphragm sucks in the medium via the inlet valve. On the upward stroke, it forces the medium out via the outlet valve.

The diaphragm hermetically seals the compression chamber from the drive mechanism. The pump transfers, evacuates and compresses the medium without any need for oil, resulting in a pure and contaminant-free operation.
