1. Application of QDX small clean water submersible pump

This series of small submersible pumps are suitable for shallow water drainage and irrigation, and are used as submersible pumps for conveying clean water. Its power is 0.12-2.2KW or greater. QDX submersible pumps are mainly used for local area drainage, such as flood control and drainage, construction, farm purification, etc. Sometimes the volume ratio of solid impurities in the water may be relatively high, sometimes exceeding 0.1 /%, even reaching 1%-2%, which places higher requirements on the wear resistance and mechanical seal of the small submersible pump parts.


Small submersible pumps are also widely used in rural underground water pumping, farmland drainage and irrigation, garden irrigation and household water. They can also be used to pump out industrial water, breeding water, etc.


2. Characteristics of QDX small clean water submersible pump

The small submersible pump consists of three parts: a water pump, a seal and a motor. The motor is located at the upper part of the electric pump and is a single-phase or three-phase asynchronous motor; the submersible pump is located at the lower part of the electric pump and has a centrifugal impeller and volute structure; the water pump and the motor are connected by Double-end mechanical seal, each fixed stop uses "O"-shaped oil-resistant rubber sealing ring as static seal.


The rotating shaft of the QDX submersible pump is hard chromium plated, which effectively improves the wear resistance and corrosion resistance of the shaft and facilitates the maintenance and disassembly of the impeller.

·The motor is equipped with a thermal protector, which can automatically disconnect the power supply to protect the motor in the event of phase loss, overload, motor overheating, etc.


3. Conditions for use of QDX small submersible pump


  • The medium temperature is not higher than +40℃,

  • The PH value of ordinary water pump medium is between 6.5-8.5; the PH value of stainless steel submersible electric pump medium is between 4-10

  • The volume ratio of solid impurities in the medium does not exceed 0.1%, and the particle size does not exceed 0.2mm; if the particle diameter is large or the content is large, you can choose a submersible sewage pump product.

  • The power supply is single-phase voltage 220V, three-phase voltage 380V, frequency 50Hz, and the voltage fluctuation range is 0.9-1.1 times the rated value.

  • The submersible depth does not exceed 5m. If the pumped water level is relatively low and cannot submerge the pump body, it is recommended to use a small stainless steel submersible pump. The cooling method of this pump adopts the method of sucking down and pumping out to cool the motor with fluid.

  • The diving depth does not exceed 5 meters
