Marine membrane pumps are specialized pumps designed for seawater and marine applications, utilizing flexible membranes to move fluids efficiently. These pump systems are highly durable, corrosion-resistant, and ideal for handling abrasive or corrosive liquids in harsh marine environments. They are commonly used in desalination, ballast water treatment, and offshore oil and gas operations.
