The water-jet pump is used for pumping water from cellars, pump shafts, building sites etc. It is also used as a water supply pump in places that are inaccessible to fire-fighting vehicles, or in cases where the low water level of rivers or marshland renders pumping with classical pumps impossible.
The pump can be used wherever there is a low water level. In addition to classical electric and motor drives, it can also be driven by the kinetic energy of water from hydrants.
A pressure of 0.2-0.3 MPa in the hydrant suffices to empty a normal-sized cellar almost completely. The pump’s functioning is unaffected by the presence of mud, grass or other impurities in the water.
