Submersible Well Water Pump

Submersible well water pump can be divided into two kinds, one is shallow well pump, the other is deep well submersible pump. Shallow well pump, as name suggests, used for shallow well. It is a kind of centrifugal pump with long transmission shaft, its structure is simple and high efficient. Compared with shallow one, deep well submersible pump is more broadly used.
Submersible well water pump is an important water supply device. It is used in residential water supply, agricultural irrigation, industrial cooling, sea water lift, geothermal heating and ship load.
It is consists of four main parts. They are water pump, submersible electric motor, water pipe and control switch.

  • Our submersible well water  pump uses water cooler 3 phase submersible motor, clean water is filled in for cooling down heated motor and lubricating shaft bearing. Pressure regulating film at the bottom of motor is used to adjust inflation water pressure difference inside caused by increasingly heated motor.
  • Two oil seals are installed in opposite direction with thawing ring, this structure is able to efficiently stop sand from well falling into pump.
  • Pump shaft and motor shaft are tied together with coupling, with pressure regulating film installed at the bottom of electric motor, so that pump shaft is unable to move above when working.
  • Motor and pump shaft use water as lubricate medium.
  • APK choose high quality submersible motor winding wire as stator wingding, leading to high insulating.
  • We use centrifugal impeller and adopt vertical style, making our simple and high efficient.

Working Process

When submersible motor starts working, impeller rotates in high speed. Then vacuum situation is formed at the entrance of inlet, water is pumped near impeller. Fast rotated impeller gives water centrifugal force, making it produce pressure force and dynamic force and pushing itself toward next impeller. With added impeller, pressure of water is also added gradually. At last, water flows out of pump through water pipe.

Submersible water well pumps from APK is of high rusty resistance and anti-aging, it is able to transfer water under 120℃, and is identified by the Ministry of State.

Want to know more details?


  1. Our pump has high head and short pump body, so that the whole height is narrowed for good stability.
  2. Diameter of pump shaft far more bigger than national standard in case of better safety.
  3. We choose HT200 as casting, when normal casting keeps under HT150. Giant deep well submersible pump uses ductile iron or steel to enhance its load capacity.
  4. Carefully designed check valve by APK ensures giant submersible pump safely working. Normal pump may suffer the danger of falling into well because of large backwater hammer, it will bring large impact force so that valve body get easily broken. Our pump can well avoid the situation.
  5. Axial force is designed small so that motor’s service life can be prolonged.

Using Condition of Submersible Well Water Pump

  • Voltage

  1. Rated voltage should be 380v ± 5%, frequency between 50Hz ± 1%;
  2. Transformer’s loaded power should be 75% less than its capacity;
  3. For motor power more than 45Kw, distance between well and transformer remains within 20 meters; If more than 20 meters, transmission line specifications should be two levels higher than cable.
  • Protection of Device

  1. The control device of water pump needs to be able to protect pump when situation as short circuit, lack of phase, overloaded and overflow happens. Thus when installing pump, personnel from APK will carefully adjust the figures so that pump can be work smoothly.
  2. If pumps have to be installed by yourself, we will give detailed description to you, and make sure the pump is installed correctly.
  • Water Quality

  1. Clean water without corrosion should be transferred;
  2. Sediment content remains less than 0.01%;
  3. PH level stays between 6.5-8.5;
  4. Chlorine content within mg/L;
  5. Distilled water or at least clean water needs to be filled within electric motor.
