Abstract
A grinding pump for pumping liquid containing solid and semi-solid matter having an improved efficiency and which requires a lower operating rpm while exhibiting an increased flow rate. The pump includes: a housing having a chamber; a shaft rotatably disposed within the housing, a comminutor on the shaft within the housing and having a helical blade, and an impeller having a vane; and a shredding liner secured to the housing structure in the chamber, so as to cooperate with the comminutor and impeller vane in shredding and pulverizing the matter.
