HERMETIC pumps are completely self-contained centrifugal pumps without any shaft sealing, driven electro-magnetically by the canned motor. The CNF model has been specially developed for pumping liquefied petroleum gas. This single-stage pump design now allows for the pumping of liquefied petroleum gases with an extremely steep vapour pressure diagram. There is no need for external re-circulation of the partial flow into the suction vessel and the separator.

The pumps use a single-stage impeller mounted directly on an integral induction motor. The pump volute casings and impellers are derived from the standard chemical pumps as defined
by EN 22858; ISO 2858.

Operating range

  • Capacity Q: max. 50 m3/h
  • Head H: max. 57 m.c.l.

Application sector
Liquid gases as e.g. R 717 (NH3), R 22 (Frigen), CO2, R 134a, R 404a, R11, R12, baysilone (M3, M5), methanol, silicon oil KT3, syltherm, lithium bromide. In principle the refrigeration pumps are suitable for use with all refrigerant liquids. Please consult for any fluids not listed above.
