DCS Twin Screw Pump

  • Twin Screw Pump

The DCS is a twin screw pump, with sanitary design, suitable for use in the dairy, food and beverage, cosmetics, etc.
The flow is uniform and in an axial direction, so there are no changes of volume or physical properties of the product. Therefore it is an ideal pump for handling shear-sensitive fluids.
It has a high suction lift capability with very low NPSH values.
It is capable of pumping liquids with high viscosity, but also with low viscosity, so it can be used as a CIP-supply pump.
The design ensures a fully cleanability and drainability.
