Marine water jet ejectors

Water ejectors are vacuum pumps driven by water (or the like) or high pressure steam. They use the kinetic energy of the driving medium to suck in gases, vapors or other liquids, and then release the resulting mixture against back pressure.

Main parts of the ejector are inlet housing, nozzle, mixing chamber and diffuser. The ejectors are self-sucking and are easily activated by simply turning on the working water stream.
