The Serfilco HE chemical pump is capable of total resistance, both internally and externally with its non metallic construction of all wetted components, choice of seal assembly and elastomer materials. This pump has an enclosed centrifugal impeller. Engineering type plastics provide application to a variety of matter which would be corrosive to other materials of construction. The totally enclosed impeller allows this chemical pump to operate at peak horsepower efficiency across a broad range of operational flow and head requirements. Double mechanical seal model requires water lubrication of seal faces and allows it to be used for solutions containing abrasives, high salt concentrations and electroless plating solutions. Look and see if the Serfilico HE chemical pump is right for you.
