Ejectors

Stripping ejectors (eductors) are jet pumps driven by water or oil supplied from conventional pumps. The combination of high quality material and skilful construction offers the most effective solution to meet onboard requirements. Stripping ejectors, which have become standard on most ships being built today, are efficient liquid jet pumps for stripping of: -Cargo tanks -Ballast water tanks -Cargo holds -Engine rooms -Bilge, etc.
