Product Description

Product Description

QJ well submersible pump is a water lifting tool, with the motor and pump integrated into a whole body and submerged into water. It's used to draw ground water from a deep well , from a deep well, or from river, reservoit and aqueduct etc,. mainly for agricultural irrigatrion, water for human bein and livestock in plateau areas , water discharge in cities, factories , railways, mines and construction sites.
Product Features
(1) Integrated body of motor and pump, submerged operation of great safety.
(2) No special requirements on borepipe and ascending pipe (i.e. it can be used in steel pipe well, ash pipe well and shallow well; if pressure permits, steel , rubber and plastic pipes can all be used as ascending pipe.)
(3)Easy installation, operation and maintenance, small occupaction space, amd no need of a pump room

(4) Compact amd somple structure and small volume.

Working Conditions
(1) Three-phase AC power supply of rated frequency at 50HZ and rated voltage at 380+_5%
(2)Pump inlet shall be kept below the dynamic level by 1 meter, but the submerged depth shall not exveed 70meters below the static level. And the lower part of motor shall be kept at least 1 meter to the bottom of the well.

(3) Generally, water temperature shall not be higher than 40℃.

(4)Water quality: 1) Sand content in water not greater than 0.01%( weight ration)

2) PH value between6.5~8.5
3) chlorine ion content not greater than 400mg/l
(5)Well shall be straight and slippery with no disalignment of borepipes.

Pump Part: At the top of submersible motor pump,the centrifugal pump is connected with motor by rigid shaft coupling.The bearing is water lubricated.The backpressure valve is fixed on the top of the pump to avoid the working parts being damaged by the returned water in pump when the submersible motor pump stops.The water in pump can flow away through the drainage hole in the valve in case the pump is broken in winter.(Note:There is no backpressure valve in low head submersible motor pump).

Motor Part: At the bottom of submersible motor pump,closed water-filled structure,guiding bearing and thrust bearing use water lubricated material.The compensation diaphragm is fixed on the bottom of motor to adjust the differential pressure caused by the ring temperature of motor.The sand-proof structure is fixed on the top of motor to prevent mud and sands to enter inside of motor.

♣ Deep Well Pump Advantages

Easy installation

Low noise, high temperature resistence, long service life.

Fully operating in water avoiding entering air.

Replacing the emergency pump quickly when the pump breaks down in harsh environment such as high temperature

water tank or pool,or somewhere that are inconvenient for man to maintain.

Portable design with its small size and light weight. so you neednt install bay bolt.

Working conditions

1. 380V (deviation≤5%), 50Hz (deviation≤1%), 3 phases

2.Electric motor must be full of clean water

3.The first piece of impeller of pump should be at least 2m or more below dynamic water level. The distance from Pump to static water level should be not more than 70m. The distance from motor base to well bottom should be not less than 3m.

4.Water temperature should be not more than 20℃

5.Sand content of water (based on mass of sand) should be not more than 0.01%

6.PH should be 6.5-8.5

7.The content of hydrogen sulfide in water should be not more than 1.5mg/l

8.The content of chloride ions should be not more than 400mg/l

9.Water yield of water source should satisfy the demand of pump running.


1.100% copper rewindable wire
2.High efficiency
3.Fast delivery time
4.Dry run pretection

The Choice of Submersible Motor Pump
The followig content should be understood in order to choose and operate submersible motor pump correctly:
1 Understanding all clauses mentioned in operation conditions
2 Pay attention to the diameter and the depth of well
3 Pay attention to the static water level and the flowing water level of well
4 Pay attention to the water surging capacity of the well
The capacity,head,and the diameter of full set should be shosen according to the water surging capacity,the depth and the diameter of well.The water surging capacity of well should meet the requirement of the capacity of submersible motor pump,so that the submersible motor pump can be under the water totally when it works.
