Horizontal, quergeteilte, fördermediumgeschmierte, morestufige Gliederpumpe with Radialrädern, Einlauf axial und radial einströmig. Horizontal radially split product-lubricated multistage ring-section pump with radial impellers, axial and radial single-entry inlet.
KSB has introduced a new variant of the high-pressure pump of the HGM type. The new variant has been specially developed for the energy transition and supports the transition from coal- or gas-fired power stations to smaller installations that are fueled sustainably.
During the development of the new variant with the type designation HGM-S, a lot of attention was paid to high reliability, ease of maintenance and efficiency. This is evident, among other things, from the internal, medium-lubricated sliding bearings, which do not require an external lubrication system.
Smaller bearing distance
The small distance between the bearings reduces the vibration level of the pump, which significantly reduces wear. The combination of suction impeller and axial supply line ensures a particularly low NPSH value and therefore good suction performance. Thanks to the axial inflow, the new pump is extremely compact and therefore space-saving.
The shaft is sealed on the drive side by a mechanical seal, which is easily accessible from the outside. Due to the design of the seal and the pump, no external cooling and lubrication circuits are required. This significantly simplifies the stock of parts and maintenance.
The largest capacity of the new pumps is 390 m³/h. The maximum head is 1,000 meters. The electric drive powers range from 10 kW to 1,300 kW. The materials for the houses can be chosen from cast steel or stainless steel. All impellers are cast from high-quality stainless steel.
