Both the pump casing, the impellers and the lantern piece with bearing support of this self-priming pump consist of electrolytically polished precision casting in stainless steel 316L. This results in a robust, reliable pump with a very fine surface structure. This self-priming side channel pump is used in various applications where air must be pumped in against a high back pressure in the discharge line. The MSCP has exceptional suction power and air handling capacity. This means it can completely empty the suction line, even with foaming and slightly more viscous liquids. It is often used for unloading trucks and pumping in high silos.
