SUBMERSIBLE PUMP

     

    1.1 Brief introduction
    (1)QY(Q) series medium-sized submersible pumps are composed of vertical induction motors and pumps with reasonable design, compact structure, excellent performance, safety and reliability, which is easy to use.
    (2)The structure of submersible pumps and motor are coaxial straight league, high-lift pumps are equipped with pressure relief non-return valve to ensure the safety of motor pumps when stopped.
    (3)The protection monitoring device inside the motor cooperates with the control cabinet (switch) can implement effective protection for the motor.
    (4)The structure of Q type series fountain pump is a kind of environmentally friendly product which is basically similar with QY type series submersible pumps, except that the outlet pipe into steel outlet flange with the same caliber. The welding is used during installation, and the motor is dry.
