How They Work

Eductors are Liquid Jet Pumps that use water or other liquids under pressure to create a pumping action. In standard eductors the inlet pressure liquid discharges through a single nozzle to start the pumping action. They are self-priming and can handle liquid and solid mixtures. There are no moving parts to break down or wear out. Eductors are available with flanged or threaded connections, for portable use or for permanent installation. They are used to pump liquids from chain lockers, bilges, cargo holds, tanks or any space that has to be pumped dry.

Bilgemate Eductors are peripheral jet type eductors with a straight through unrestricted flow for the suction liquid, allowing larger pieces of suspended solids to be handled. The Inlet pressure liquid is discharged through a multi-jet nozzle which makes it possible to handle larger volumes of air. All these characteristics make the Bilgemate suitable for pumping bilges, stripping ballast or priming large pumps. They cannot lose suction. Every gallon of inlet liquid (sea water) can pump up to 1½ gallons of suction liquid such as bilge water. In all VM eductors, the nozzles are renewable and replaceable.

Portable Eductors: 1316-1": 300-1½: 1544-2½": & 1554-4" use inlet pressure from fire main or other source of liquid pressure. They are usually lowered into the space to be pumped out. They can also be used with a length of suction hose

The Deck Eductor is powered from the fire main, and remains on the deck. Only the non‑collapsible suction hose goes into the tank to dry out remaining puddles of liquid.

Permanently installed, VM1802; VM# 1542 & VM# 1903 models are used to strip bilges, ballast, or other spaces that regularly have to pumped out.

The Bilgemate peripheral jet eductors, VM# 925, 964, 976 & 978 – are used to pump bilges or cargo spaces that may have a mixture of solids and liquids. Widely used on fishing vessels to pump fish and shell slurries. Especially useful in grey water service.
