A ship is a hostile place for a pump — constant saltwater and spray, cramped spaces, and fluids that range from seawater to fuel to chemicals. Air-operated diaphragm pumps earn their keep aboard because there’s no electric motor to fail or spark, they run dry when a bilge empties, and stainless or plastic builds shrug off the salt.
From bilge and ballast to fuel transfer and tank cleaning, a properly specced Wilden handles shipboard duty without the corrosion and electrical worries of a motor-driven pump.
We supply these genuine, with the material and any hazardous-area rating matched to the service. Tell us the fluid and where aboard it’s going and we’ll spec it.
