Suction pump DCH+

for the pharmaceutical industryscrew

The DCH+ is a twin screw pump, with hygienic 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. Design and features The DCH+ pumps are available in bare shaft construction and designed according to the EHEDG recommendations.
