CPXR Recessed Impeller ISO Chemical Process Pump

The Durco CPXR Recessed Impeller pump provides low-shear pumping of friable solids and trouble-free pumping of stringy or fibrous slurries. Solids are drawn into the vortex of swirling liquid and discharged by centrifugal force through the open area in front of the impeller with little contact.
