QS models of water-filled submersible pump, is composed of pumps, motors in two parts. Pump motor is located in the lower part, divided into single-phase and three-phase asynchronous motors. Three-phase motors are divided into two types of rolling bearings and plain bearings, plain bearings made of high quality graphite sleeve and stainless steel thrust plate, respectively withstand radial forces and axial pumps work force, stable performance, reliable quality, seals and caps composed of sand the motor seal. QS-type water-filled wet multi-stage submersible pumps are submersible pumps for short-phase asynchronous motor pumps and irrigation equipment power synthesis. With reliable waterproof sealing performance, small size, light weight, high lift, no pumping stations, no lead irrigation, maintenance and management can easily use
