As an important accessory, motor is installed with pump body as one. Submersible motor pump is used to be immersed into water for irrigation and residential or industrial water supply. With low noisy, easy installation and reliable performance, submersible motor pump becomes increasingly popular. With motor installed inside, there is no need to build a house, thus more space and cost is saved.
- Rusty resistance.
- Unique thrust bearing makes sure to bear high pressure of axial thrust.
- High efficiently energy saving
- Copper rotor and low energy saving silicon steel laminated ensures high starting torque.
- Larger shaft leads to better dynamic transfer.
- Excellent cooling performance
Power Supply Voltage
According to power supply voltage, submersible motor pump can be divided into single phase and three phase submersible water pumps. If letter“D” is added after a product model, it refers to single phase. Or it is three phase water pump. 3 phase pump is 380v, residential single phase pump is usually 220v. Compared with single phase, 3 phase is more energy saving and has better performance, thus is more widely used by pump manufacturers.
Submersible motor pump can also be divided by internal structure. There are all together four types of motors. The first is water cooler submersible motor. This kind of motor is filled with clean water or rusty resistance lubricating oil, then it is able to be used for a long time without being burnt. Submersible pumps with submersible water filled motor has to be used under three phase of 50HZ and 380 volt.
The next type is oil filled submersible motor. It is sealed structure filled with insulating oil, which means oil will be filled when motor becomes hot for working a long time. Water filled motor and oil filled motor are usually used under water.
Air cooler motor is also called dry motor. It is filled with air inside, and has simple structure that quite the same as ground motor. When dry motor is installed together with pump body, it is called dry motor submersible pump. This kind of pump uses water flow outside pump case to cool down without touching stator and rotor. The price of air cooler submersible pump is lower than oil cooler one, but it can only be used when low head and low load is required.
The last one, shielded motor. This kind of motor is used to transfer toxicity, rusty, radioactivity, flammable and explosive liquid. So stator and rotor has to be shielded in case of being rotted. The stator of the motor is closely sealed by a seal room, the seal room is formed by end ring, chassis and thin wall shield which are made by non-magnetic stainless steel. Inside the motor is fulfilled with solid material. When it is installed with submersible pumps, it can be used to transfer liquid without solid. Shielded motor can be divided into horizontal and vertical type.
Depend on position of motor installation, it can be divided into up and down pump type;
It can also be classified into exterior type, interior type, half interior type and tubular type. When fluid straightly flow out pump without going through motor, it is called exterior type. Interior type is used when water flows through the surface of electric motor. It requires motor to be of high cooling performance, it is suitable to be used in large area drainage situation and is famous for its reliable. The cooling capacity of half interior type is better than exterior type.
According to the usage of pump, submersible electric motor can be divided into seven types. They are submersible well water pumps, clean water submersible pumps, sewage or waster water submersible pumps, mine dewatering pumps, axial flow submersible pumps, well water high pressure submersible pumps and giant submersible pumps.
The main submersible motor pumps for sale in APK are water cooler pump submersible(short as QS submersible pumps) and oil filled submersible pumps(short as QY submersible pumps).

Submersible Motor Pump Price
Do you have puzzle in finding the reasonable submersible motor pump price list? It is a common phenomenon that customers would like to find cheap price products at first time, but in long term sight, buying a cheap pump is actually spending more money than buying a costly quality pumps. Though cheap for purchase price, they need to pay much in repairing and maintaining, which can be rather costly one can imagine. For APK pumps, our motor pumps are able to use for more than eight years when transferring clean water, which is far longer than normal types. Therefore, buying quality submersible motor pump is saving money for you. Detailed submersible motor pump price list will be given if you need.
Submersible Motor Pump Working
Like most submerged pumps, submersible motor pump must be immersed into water for its whole working period. Motor as the key factor, playing important role in driving other parts working. Water is sucked in under great pressure, after flowing near impeller, fast speed rotate impeller brings transferred liquid moves together and throw it away with large force. After water is thrown out of pump body, new round of transfer starts again. Hundreds of hydraulic experiments are made to make sure that whole working process is smooth and stable.
Internal Parts Design
Submersible motor pump parts are mainly include pumps body, motor, impeller, stator, shaft and copper wire etc. As it is designed as vertical types, pumps body and motor are linked together to share the same shaft. Raw materials are selected to use only, which includes 304 stainless steel motor rotor head, 100% virgin high strength PPO plastic impeller, NO. 800 silicone steel sheet as well as 100% copper wire and winding. High precision and efficient processing machining to enable good performance of each parts.
How To Get Pump Repaired
Submersible pump can be broken for several reasons, for some common fault, customers can find the reason and solution in common fault of pumps and repair by oneself. If impossible to repair by your own, or unable to find fault, you may contact a professional pumps manufacturer like us to help solve problems. Of course submersible motor pump repair price can be much higher especially when it gets broken frequently, so we strongly suggest you to buy a high quality pump at the beginning. Contact us any time for brilliant water pumps and for best submersible motor pump repair.
Submersible Motor Pump For Borewell
As name suggests, submersible motor pump for borewell is mainly used under well. In installation process, we would cover rubber tube outside pump body, protecting both pump body and well wall from being collapsed.
