The special design of the “CS” pump range means it can guarantee high levels of operation and top-of-the range performance. The parts in contact with the product are cast in AISI 316L stainless steel using the lost-wax process and are electrochemically polished. They can be supplied (on special request) made from special alloys such as SuperDuplex and Hastelloy for use in particularly aggressive operating environments. The design of the open 6-vane impeller is optimized to guarantee delicate handling of the pumped liquids. The special construction with shaft support bearing means that the “CS” series pumps can be bought with a bare shaft for subsequent quick and easy coupling with standard IEC electric motors. In the hygienic version, they have a stainless steel casing to protect the motor, supported on adjustable feet. It is possible to install an inducer on the pump intake to reduce the required NPSH value.
