The partial flow for cooling the motor and lubricating the slide bearings will be branched off at the periphery of the impeller and, after having passed through the motor, is carried back again to the pressure side. An auxiliary impeller serves to overcome the hydraulic losses encountered along the way. The return of the partial flow towards discharge side ensures that the heated motor cooling flow has sufficient pressure reserves over the boiling point curve of the medium during its return to the pump. This model of pump can be used for liquefied petroleum gases with an extremely steep vapour pressure diagram.

Application sector:Liquid gases, e.g. ammonia, freone, carbon dioxide, amines, propane, butane, vinyl chloride, ethylene oxide, chlorine, phosgene, propylene, carbon bisulphide, hydrocarbon, diphenyl (> 250 °C) etc.
