The SWFI Pump is a centrifugal pump that complies with the highest hygienic requirements of the pharmaceutical industry. Its main application is the loops of de-mineralised water of various pharmaceutical qualities.

Operating principle:

The operating principle is the one of the centrifugal pumps. Allowing to maintain the water purity in the circuit the pump is completely drainable, the parts of the pump resist the passivation system and the rigorous CIP/SIP processes.
If a double seal is installed, the sealing barrier is the sterile water of the process, the flow of which is regulated with a needle valve.

Design and features:

The pump outlet is at 45º with the ½" clamp drain port.
Clamp connections (standard).
Open type investment casting impeller.
Interior surface finish Ra<0.5µm.
Hygienic mechanical seal.
3A certified pump.
Robust cast lantern. 
Motors: IEC B5, IP55, F class insulation.
