LABOPORT diaphragm vacuum pump, corrosion and chemical resistant, also self-drying

KNF

The chemical resistance is ensured by the pump head made of Teflon and the membrane coated with Teflon as well as the FFPM valves.

Application: as a vacuum source for rotary vacuum evaporators, for solvent media and also for simpler tasks, such as:

for vacuum filtration
for evaporation
for replace water jet pump
and for drying tasks

The self-drying membrane vacuum pump is a KNF patent: the vacuum does not decrease even during the drying period, because the sucked space is closed by a valve.

Due to the modified TFM components, the N 810 FT.18, N 820.3 FT.18 and N 840.3 FT.18 devices are suitable for transporting gas according to ATEX II 2G IIB+H2 T3X classification.

(Conformity applies only to gas transport components, the device cannot be installed in an ATEX space.)
