Water operated Ejectors are used for raising water from tanks, mixing liquids, and for water softener regeneration.
Operating pressures recommended are between 20 and 40 p.s.i. (1.3 and 2.7 bar), but higher pressures may be used.
Suction lifts up to 24 ft. may be obtained by using motive water at 40 p.s.i.
To maintain the water seal, the discharge piping must be arranged with a bend or other slight restriction to ensure that the motive water completely fills it.
