Ruhrpumpen's engineering team designed a vertical molten salt pump for a concentrated solar power plant developed by Yumen Xinneng.
Pumps for water desalination
Over the last 30 years, desalination has grown to be a viable and sustainable alternative supply of water for the growing demand for potable water for human consumption, agricultural irrigation or industrial use.
From salt to tap water, we are committed to the development of cost-effective and environmentally friendly pumping technologies that improve the water access and quality for communities around the world.
Pumps for all services in desalination plants
- High-pressure membrane feed pumps
- Source water intake pumps
- Booster pumps
- Filter backwash pumps
- Chemical dosing pumps
- Brine circulation pumps
- Distillate extraction pumps
- Cooling seawater pumps
- Potable water transfer pumps
- Energy recovery devices [see VTG pump]
Our pumps can be found on desalination plants that use different methods, such as:
- Reverse osmosis
- Multi-stage flash distillation
- Multi-effect distillation
Pumps for desalination in reverse osmosis plants
The most common method of desalination, reverse osmosis is a process by which salt is removed from sea or brackish water through filtration. Salt water is pumped at a high pressures through semipermeable membranes that impede almost completely the passage of salts, thus obtaining fresh water.
Ruhrpumpen can provide pumps for seawater intake, pre-treatment and transfer, as well as high-pressure feeding pumps for the reverse osmosis membranes, with great energy efficiency and corrosion-resistant materials.
Municipal water and wastewater pumps
Municipalities require reliable, energy efficient and environmentally friendly equipment for pumping of clean water and the proper disposal of wastewater. In Ruhrpumpen, we offer water management pumping solutions for the transportation and distribution of potable water, the treatment and reuse of wastewater, and storm and flood water disposal.
- Municipal water pumps
- Municipal wastewater pumps
- Booster pumps for municipal water
- Municipal sewage pumps
Throughout the whole water cycle in municipalities, our cost-effective pumps guarantee a long life-cycle with minimum maintenance. From raw water intake, to its treatment and distribution, flood control and drainage, wastewater collection and treatment, our municipal pumps ensure water is available where it is needed.
We are your single source supplier... whether you need a new pump, support on installation, spare parts or repair of an existing pump, our Global Service Network is ready to assist you throughout the entire process.

Pumps for Concentrated Solar Power Plants
One of the fastest growing energy markets around the globe, as the Sun is the cleanest, most abundant renewable source of energy available.
Concentrated Solar Power (CSP) Plants, also known as concentrated solar thermal, combine three major systems to produce electricity by collecting and concentrating sunlight with mirrors and lenses in a Heat Transfer Fluid (HTF). Through a heat exchanger system, pumps move the HTF to heat water and generate steam. The power block then uses that steam to generate electricity through a turbine generator. Throughout these systems, pumps operate in services such as: molten salt, heat transfer, boiler feed, condensate extraction, cooling water and auxiliary services.
Due to its nature, CSP plants depend a lot on direct solar radiation. They have a variable operation, with a daily start and stop, and require heavy-duty pumping equipment cabable of handling high temperatures and pressures. To increase efficiency, concentrating solar power plants store the heat obtained during the day in molten salts, enabling them to continue to generate electricity even at night. Molten salts can reach temperatures as high as 1100°F (600°C), which demand for highly-engineered transfer pumps [see VLT pump].

Ruhrpumpen's experience in the power generation market has provided highly-engineered and special-purpose pumps for CSP services.
Reference project: ANDASOL III Solar Power Plant
ANDASOL III, developed by Solar Milennium Group, is a CSP plant in Spain with the capacity of delivering electricity to 200,000 homes. It relies on a HVN 12x17 pump for the as the heat transfer fluid pump of synthetic oil through the parabolic troughs. Due to the variable operation and daily starts and stops, along with temperatures as high as 750°F (400°C) that needed to be met, Ruhrpumpen selected this HVN pump with casing and impeller fabricated in chrome steel, plus cooling systems and variable frequency drives.
