Grundfos supplies pumping solutions for seawater intake. Depending on the flow requirements, salt content, and whether the seawater intake is offshore or onshore, pumps are available for both dry and submerged installation that matches the corrosion risk. Seawater is then pumped for desalination at reverse osmosis plants, for which Grundfos also supplies corrosion-resistant pumping solutions.

Specially designed corrosion-resistant variants of SP submersible multistage pumps are available, used where the water has a high concentration of hydrocarbons and many chemicals. Find out more about the pumping of corrosive liquids in the pump liquid guide at the Grundfos Product Center.
