Saltwater or sea water pumps

Saltwater pumps and sea water pumps are those that are specifically designed to be able to withstand the harsh effects of a brine solution which can corrode and damage materials such as metals. On marine vessels, these pumps may be employed for the purpose of transferring ballast or for use in firefighting operations. Attention needs to be paid not only to the metal used in the pump housing and impellers but also seal materials as well. Materials such as stainless steel and bronze are often used in the design and construction of these pumps, while Buna-N, Viton, and EPDM seal materials have good compatibility for sea water use.
