Flowserve Durco Recessed Impeller Pump

Durco Mk 3 Recessed Impeller Pump.jpgThe Durco Mark 3 ISO Recessed impeller pump provides low shear pumping of friable solids and trouble free pumping of stringy or fibrous slurries. It combines the state of the art hydraulics of the standard Mark3 ISO pump with the vortex action of a recessed impeller.

 The recessed impeller pump boasts a wide clearance at the front of the impeller allowing passage of larger solids. 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, minimizing particle degradation, Furthermore , the air & gas handling ability of the pump is improved.

Available in additional configurations of vertical sump pump or a close coupled unit.
