KSB’s new high-pressure pump variant for biomass power plants

Responding to the growing number of smaller power stations incinerating biomass or refuse, KSB Group has developed a new variant of its HGM high-pressure pump.

The new HGM-S variant was designed to be reliable, service-friendly and economical.

The pump’s internal, product-lubricated plain bearings, for example, do not require any external supply systems while the small spacing of bearings lowers the vibration level of the pump. This markedly reduces wear. The combination of suction stage impeller and axial inlet results in a very low NPSH and good suction characteristics. With its axial inlet, the new pumpset is compact and space-saving.

The shaft is sealed by a mechanical seal at the drive end that is easy to access from the outside. Given the seal design and smart arrangement in the pump, no external piping is needed for cooling and lubrication circuits. Spare parts stock and servicing are kept simple.

The largest flow rate of the new pumps is 390 cubic metres per hour and their maximum head is 1000 metres. The electric drive ratings range from 10 kW to 1300 kW. The materials for the casings are either steel or stainless steel. All impellers are cast of high-quality stainless steel.

KSB offers a five-year warranty on this product.
