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.
