QS type submersible pump (hereinafter referred to as electric pump), the electric pump consists of two parts: water pump and motor. The water pump is located at the upper part of the electric pump and is a centrifugal structure. The electric motor is located at the lower part of the electric pump and is a water filled three-phase asynchronous motor. The stator winding and iron core of the water filled electric motor are directly immersed in water, which has good cooling effect and does not produce pollution, thus breaking through the disadvantages of water leakage into the motor cavity caused by 'O' - shaped sealing rings, mechanical seals, etc. during the operation of other electric pumps, greatly improving the efficiency of the electric pump.

1. The motor and water pump are integrated and operate underwater. The structure is simple, energy-saving, efficient, safe and reliable.
2. Beautiful appearance, light weight, low noise, no pollution, strong adaptability to the installation environment, significant cost savings, and no impact on the building and natural landscape.
3. Easy to install, use, and maintain, with a small footprint and no need to build a pump room.

1. Installation: The electric pump should operate completely submerged in water, with a diving depth of no less than 0.5 meters and no more than 5 meters.
2. Power supply: A three-phase AC power supply with a frequency of 50Hz and a voltage of 380V (allowable deviation+5% -10%).
3. Water source: Generally non corrosive clean water with a sand content of no more than 0.02% and a pH value of 6.5-8.5. The extracted water temperature is not higher than 40.
4. The ambient water temperature should not exceed 40 degrees Celsius.

1. Ship bottom drainage;
2. Underground water lifting, water tower water delivery;
3. Urban construction, industrial and mining water supply and drainage;
4. Irrigation, well irrigation, and sprinkler irrigation in farmland and gardens;
5. Drainage and flood prevention;
