DCH Hygienic Twin Screw Pump

The DCH is a twin screw pump, with hygienic design, suitable for use in the food, dairy, beverage and cosmetic industries.
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 drain ability.
