Due to their excellent suction capability and reliebility, water ejectors are frequently used for marine applications shuch as:
Water ejectors are vacuum pumps, driven by a high pressure water (or similar medium) or steam. They use kinetic energy of the driving medium to suck in gases, vapors or other liquids and then discharge the resultant mixture against a counter pressure.
Turbine Works manufactures water ejectors for industrial and marine purposes.
Ejectors are simple in design and reliable in operation since they don't have movable parts like stadanrd pumps. Major parts of an ejector are a inlet casing, nozzle, mixing chamber and diffuser. Since there are no moving parts, no lubrication is necessary and maintenance is minimal. Ejectors are self-priming and easily activated by simply turning on the flow of the driving water.
Water ejectors depending on application can be manufactured out of various materials ranging from bronze, steel, stainless steel with nozzels usualy being made out of hi grade stainless steel or monel.
