HERMETIC pumps are completely selfcontained centrifugal pumps without any shaft sealing, driven electromagnetically 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.
