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.
