Suction pump DCS

for the pharmaceutical industryscrew

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. Design and features The DCS pumps are available in two versions: close coupled and bare shaft construction. They have a two part design (pumpcasing and separate flange). The mechanical seals have a sanitary design. When required, other materials can be used. Motor Triphasic induction motor with B5 flange and B3 legs for monoblock version. Triphasic induction motor with B3 legs for bare shaft version. In both versions the motor complies with the IEC standards, efficiency class according to EC regulation, IP 55 protection and F-class insulation. 3 phases, 50 Hz, 230 V Δ / 400 V Y, ≤ 4 kW 3 phases, 50 Hz, 400 V Δ / 690 V Y, ≤ 5,5 kW Materials Parts in contact with the product 1.4404 (AISI 316L) Bearing support 1.4401 (AISI 316) Gear housing aluminium Gaskets in contact with the product EPDM Mechanical seal Rotary part silicon carbide (SiC) Stationary part silicon carbide (SiC) Gasket EPDM Surface finish Internal Ra ≤ 0,8 μm External Matt Options Mechanical seals: TuC/TuC Knife-edge single mechanical seals Double mechanical seals Gaskets: FPM, HNBR, FFKM Heating chamber Bareshaft version
