PUMP STRUCTURE DIAGRAM

  • TECHNICAL FEATURES
    The series QJ pumps are manufactured to be
    coupled to NEMA standard motors.
    The series QJ pumps are improvement in the
    design especially for the impeller and diffuser,
    offering the following advantages:
    -High head for single stage impeller and diffuser
    than the usual one so that similar performance
    are given by reduced number of stages.
    -Axial thrust load on the motor shaft is
    obviously reduced leading yo increased
    average life of the motor.
    -The built-in non-return valve is easy to
    remove and to inspect.

  • USES
    -Water feeding plants for domenstic and
    industrial aplications.
    -Building pressurization plants.
    -Fire fighting systerm for small and medium
    plants.
    -Fountains.
    -Sprinking and flow irrigation plants.
    -These pumps are desined to life water from
    wells of size 4" and 6",up to maximum
    -Pressure head of 228 meters and 300 meters.

  • MATERIALS
    -Casing both of pump and motor,pump shaft;
    stainless steel AISI 304
    -Outlet and inlet:bronze
    -Impeller and diffuser,non-return valve:
    thermoplastic resin PPO.
