Power Generation
Waste Incineration Plants

Conventional power plants produces electricity by the conversion of primary energy into electrical energy. For this conversion, the fossil fuels are burned and water steam is generated. This steam is used to drive a turbine connected to the generator. Finally the steam is condensed back to water so that the process loop is closed.

Focused solutions and products in power plant engineering:
- Boiler feed pumps and booster pumps for pressures of up to 160 bar
- Cooling water pumps for flow rates of up to 80,000 m3/h
- Auxiliary and pumps for various applications
- Service for all pumps in power plants
- Spare part supply for all pump types

Boiler Feed and Booster Pumps

The SIHImulti pumps are used as boiler feed and booster pumps in small to medium sized power plants (such as waste-fuelled power stations, combined cycle power plants or industrial power plants) with a pressure of up to 160 bar. These modular pumps are designed for maximum efficiency. The axial thrust of pumps used for a pressure up to c. 60 bar (MSL/MSM) is hydraulically balanced by a patented balance drum system. The required thrust compensation for pumps with higher pressures of up to 160 bar (MSH) is provided by a combination of a balance drum with a balance disc. The shaft are sealed by mechanical sealing.

Cooling Water Pumps

With the integration of MAN and Balcke-Dürr products in our range, Ludwigshafen had become a centre of competence for large cooling water pumps over the last few years. We provide cooling water pumps for all types of power plants up to a volume of 80,000 m3/h. Using an optional pre-rotational swirl control the pump can be adapted to a change of liquid height at the inlet during operation e.g. generated by a tidal range. If an adjustment of the flow during operation is necessary the pumps can be equipped with adjustable blades. A special mechanism changes the angle of the blades during the operation so that the flow can be adjusted with maximum efficiency. Due to the unique design, there is only load on the gear while the blades are being adjusted. During normal operating the gear remains load-free.

Auxiliary Pumps

Besides the main pumps used in power plant, the range of products offered by Sterling SIHI includes all auxiliary and ancillary pumps required in power plants, such as fire extinguisher pumps, condensation evacuation pumps, deionised water pumps, screened water pumps, intermediate water cooling pumps and emergency cooling pumps.

Depending on the application or design involved, the pumps employed can be either centrifugal, side channel, volute or multistage ring section pumps.



Municipal Water Supply

The sources of drinking water, both tap water and bottled water, include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals.

Typical applications for Municipal Water Supply:

- Drainage

- Irrigation

- Product Transfer

- Reverse Osmosis



Municipal Water Treatment

Water treatment plants using micro-pore filtration or reverse osmosis will not only generate a contaminated backwash or bypass waste stream, but also concentrated filter medium and membrane cleaning wastes.

Typical applications for Municipal Water Treatment:
- Mixing
- Product Transfer



Steel Mill Industry

The principal facilities of hot strip mills include three reheat furnaces, vertical scale breaker, roughing stand, reversing rougher with edger, six finishing stands and three down coilers.

Typical applications in Steel Mills:

- Cooling water

- Descaling



Mining / Mineral Extraction (mining)

Mineral processing in the mining industry can be defined as the economic recovery of a valuable commodity from a mineral deposit.

Typical applications in Mining / Extraction:

- Crystallisation

- Drainage

- Product Transfer



Pulp and Paper Industry

In a pulp mill, the fibres are separated from one another into a mass of individual fibres and after separation, the fibres are washed and screened to remove any remaining fibre bundles. The pulp may then be used directly to make unbleached paper, or be bleached for white paper. Pulp may be fed directly to a paper machine or dried and pressed into bales to be used as a raw material by paper mills worldwide.

Typical applications in the Pulp and Paper Industry:

- Cleaning

- Vacuum Drying

- Washing
