AirJet Mini membrane vacuum pump/compressor

The AirJet Mini single-head membrane vacuum pump is suitable for a variety of applications in the laboratory and industry. The dry running membrane vacuum pump is able to pump, compact and evacuate 100 % oil-free, which means it does not distort results or add impurities, and can also be used as a compressor.

The membrane features a long service life and is available in two versions, EPDM for general applications and PTFE-coated for special applications.
Magnetic drive pumps

Magnetic drive pumps

The magnetic centrifugal pumps are suitable for pumping acids, alkalis, alkaline and galvanic baths, photographic chemicals as well as radioactive, sterile and highly corrosive liquids. The non-contact magnetic drive means that no dynamic shaft seals are required, so the pump housing is hermetically sealed and does not allow any leaks.
