Centrifugal pump with solids cutting action

摘要: A centrifugal pump has an impeller rotatable by means of a drive shaft. The plurality radially extending vanes connected to hub and partial back shroud with sharpened leading edges. casing plate adjacent the side impeller. Spiral grooves on interact edges aid in protecting area between cutting solids expulsion through output port. Cutting bars front project into intake cut incoming liquid mixture. preferred form that extend generally radial plane. These sweep backwardly from their each vane is given double twist edge its trailing edge. This both effective slicing action efficient transmission kinetic energy fluid.
