Seawater lift pumps feed cooling and firewater systems on most offshore installations. If they run dry or the discharge chokes, a lot of downstream kit is suddenly at risk.

Ajax flow switches confirm flow on the pump discharge or in the distribution header, giving an electrical signal the moment something goes wrong. Bamford instruments are known for robust construction and long service life, which matters when access is by helicopter and weather windows. ATEX flameproof versions are available where the area classification calls for it. Speak to the manufacturer about materials and connections for seawater service.
