Discontinuous-operation high-speed gear pump

Discontinuous-operation high-speed gear pump is suitable for rapid and effective processes. Gear pumps can play a role in relieving the extruder gear of dynamic pressure build-up by the start-stop method.

Discontinuous-operation high-speed gear pump features:
In some areas of rubber processing applications, process technology constraints mean that a discontinuous operation of the extrusion system yields better results. In particular, to relieve the extruder gear of dynamic pressure build-up, extrusion gear pumps have been proven to be exceptionally useful and reliable with the start-stop method. In this case, the dynamic loads that are generated make rigorous demands on the pump bodies, shafts and bearings.

To withstand the high bending forces, the Discontinuous-operation high-speed gear pump series is equipped with special shaft bearing properties. After long-term testing, the HSE series offers gear pump models of the latest generation that deliver the same lifetime of service as a conventional gear pump even at high dynamic loads.
