Vacuum Technology

A diaphragm pump is a positive displacement pump, that uses a combination of the reciprocating action of a rubber or teflon diaphragm and suitable non-return check valves, to pump a fluid. This type of pump is also referred to as a membrane pump. We supply these pumps through Vaccubrand and KNF.

A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor, rotating inside a cavity. The simplest vane pump consists of a circular rotor, which rotates inside a larger circular cavity. The respective centers of these two circles are offset, causing eccentricity. Vane pumps can be used in low-vacuum applications, including evacuating refrigerant lines in air conditioners,laboratory freeze dryers, vacuum experiments in physics and is extensively used in semiconductor low pressure chemical vapor deposition systems. Once again Vaccubrand and KNF represent popular suppliers of these pumps. Through Vaccubrand and KNF we also provide additional measurement and control devices for vacuum measurements.

This section of our site also provides information on other vacuum related products, such as Binder vacuum ovens and desiccators.
