RSU – Axial flow centrifugal pump in metal

Model: RSU

Horizontal chemical circulating pump type RSU is designed for high flow rates at relatively low heads. By using specially designed screw impellers or propellers in Siguss is excellent suitability for the circulation of different acids, e.g. for the evaporation of spent and contaminated sulphuric acids as well as for the concentration of raw phosphoric acid. In order to achieve a sufficiently resistant - usually difficult to cast and machinable - materials, armoured versions are available.
