This range of high-performance water pumps expanded

| By Gerald Ondrey

This company has expanded its RDLO series from 21 sizes to 33 (photo). The pump sets are axially split volute casing pumps primarily used for clean water transport. A casing with double-volute compensating radial forces and a double-entry impeller compensating axial forces are key to a long service life. As a result, the generously dimensioned rolling-element bearings are subjected to a minimum load only. Thanks to the expansion of the series, flowrates of up to 20,000 m³/h at heads of up to 300 m can now be achieved. Because RDLO pumps are also capable of transporting seawater, the materials used include duplex steels alongside standard materials, such as gray cast iron and nodular cast iron. — KSB SE & Co.
