Boiler feed pumps ? Series HGM

They can handle flows up to 274 m3/hr (1200 GPM) and heads up to 1100m(3600 ft) at 3600 RPM. It is an environment friendly, low cost pump of reliable design, which is not only easy to install but also service. Unlike conventional pumps, which are fitted with bearings in a separate bearing housing, the new HGM is equipped with bearings built in the suction impeller and the balancing device. KSB AF has developed a special alloy cast-iron material with non-galling properties. Since the bearings are in-built in the pump and lubricated by the pump media, no external lubrication is necessary. No external cooling is required as metallic bearings are used. Due to elimination of conventional bearing bracket, the shaft becomes shorter which results in low vibrations. Balancing device with integral product-lubricated thrust bearing. Compact design and a total lack of supplementary supply lines minimize the pump?s servicing needs. The combination of an axial intake and a suction impeller yields minimal NPSH values. The stacked rotor design enables easy assembly and disassembly.
