Single or dual-head chemically resistant, dry running diaphragm pumps for a wide range of laboratory applications. They transfer and evacuate without affecting the media, i.e. media remains uncontaminated.

100% oil-free displacement, so media cannot be contaminated by transfer, evacuation or compression
High resistance to vapours and condensates
Chemically resistant, suitable for use with very aggressive and corrosive gases and vapours
Maintenance-free, environmentally friendly; the pumps use no water and so produce no contaminated waste water

Application: Fluid aspiration, degassing, gel drying, rotary evaporation, centrifugal concentration, distillation.

Includes diaphragm with patented tension optimisation, which allows the pump size to be smaller and extends the service life of the diaphragm. All parts that come into contact with the media are comprised of chemically resistant fluorinated plastics.
