With the new model series 2119 pump specialist Rietschle Thomas has overcome the problem of valve corrosion in pumping gas media containing humidity: The two-staged diaphragm pump deals easily with humidity and small amounts of condensed water. It is designed for the application in steam autoclaves, vacuum ovens and vacuum mixers.

Rietschle Thomas Engineers solved the problem by using umbrella EPDM valves instead of the common, but corrosion sensitive, stainless steel valves. Also, all aluminium parts of the 2119 are protected against corrosion by an epoxide coating. The pump console is plastic injected and gives the extremely compact pump a favourable and modern design.

The two-staged diaphragm pump reaches a free flow of 19 l/min and a maximum vacuum of -900mbar. It is suited solely for vacuum applications such as steam autoclaves, vacuum ovens, vacuum mixers and pumps for aspiration.

This new pump development from the successful diaphragm pump 2107 is available in nearly all world voltages.
