Water pump G series

with electric motorsubmersibleimpeller

Application Deep-well units are designed for use in water supply systems, for pumping and increasing liquid pressures in technological processes, reduction of ground water level, watering systems, and other industrial and residential applications. Essential advantages of type G deep-well pumps the pump unit may be installed in a suspended, standing or horizontal position without necessity to rebuild foundations may be installed in drilled, small-diameter wells without suction jackets may be installed in drilled, large-diameter wells and in large tanks, with the use of suction jackets pump unit may be installed directly in the pipeline, in a hermetic jacket in a vertical or horizontal position may be incorporated with the pump unit by-pass in parallel to the pipe line, in a hermetic jacket in a vertical or horizontal position incorporation of the pump unit is simplifi ed by the linear position of stub pipes in the hermetic jacket space requirement is minimized due to compact design standardized design of the connections and couplings of the pumps and motors according to NEMA, which is accepted and used by all deep-well pump manufacturers in the world a splined slide-over coupling enables torque to be transferred effi ciently and durably without any maintenance, for a simplifi ed assembly/disassembly/replacement and facilitated servicing the pump/motor bearing arrangement requires no maintenance, it is lubricated by the pumped liquid in the pump and by the liquid that fi lls the motor in the motor, which enables heat of energetic losses to be removed therefrom the pump unit, submersed in a hermetic jacket or tank, produces no noise
