RPROP

Axial flow centrifugal pump in metal

Pumps of type RPROP are horizontal, axial flow circulation pumps, which are fitted in standard with propeller impeller and could be executed in special cases also with inducer impeller. Additionally, there is a close-coupled design (RPROPF) available. The RPROPF can also be executed with propeller or inducer impeller, but the flow direction is only one-sided. This pump type is installed in evaporation plants, crystallisation plants, pulp and paper industries, plastic production, regeneration plant for spend acid and reaction solutions and production of titanium dioxide.
