Our models offer you maximum flexibility. They can be installed vertically, horizontally and even at angles in wells and deep wells.
The motor is filled with clean water to cool the motor and lubricate the bearings. Polyethylene insulated nylon sheath is used in motor winding, water-resistant electromagnetic wire is used, sand-throwing ring and skeleton oil seal are used in the upper pat of the motor to seal, so as to prevent leakage of internal and external media of the motor.
The water pump is a vertical single-stage,multi-stage centrifugal closed impeller, and the guide shell conveys liquid.
In order to solve the problem of different application scenarios and different pumping media, Our pumps are available in Cast iron, SS 304, SS 316, SS 316 L, Duplex SS, SS 904 L.
We test each submersible water pump before delivery, such as dynamic and static balance testing, material analysis testing, casting testing, and submersible pump submerged in water for 48 hours to test leaking or not.
1. Three-phase power supply voltage deviation dones not exceed ±5% and the frequency deviation isn't more than ±1%.
2. Motor cavity must be filled with clean water during operation.
3. The primary impeller of the pump should be immersed at least 2m under dynamic water level. The pump unit shall be less than 70m deep under static water level. The foot of motor shall be at least 3m above well bottom.
4. Water temperature no higher than 20 ºC.
5. Sand content of the water (by quality) not more than 0.01%.
6. Water PH 6.5~8.5.
7. The content of hydrogen sulfide in water not more than 1.5 mg/l.
8. The content of chloridion in water shall not be higher than 400mg/l.
9. The water source shall provide enough water for the pump to work continuously.
