Submersible borehole pump (submersible deep well pump) is high lift submersible pump .This series of submersible pumps are mainly used to solve the problem of water intake for customers. It is suitable for extracting underground water from the deep well, can also be used for rivers, reservoirs, drains and other water projects mentioned, mainly used in irrigation and water for people and livestock in the mountain plateau, also for the cities, factories, railways, mines, the use of the site for drainage. Their application fields include farmland irrigation, deep well water lifting, mine drainage, emergency rescue, sea water lifting , urban water supply and groundwater sources raised by enterprises. In order to solve the problem of different application scenarios and different extraction media for customers, the deep well submersible pumps produced by our factory are cast iron deep well submersible pumps and 304 stainless steel deep well submersible pumps, 316 stainless steel deep well submersible pumps and 316L stainless steel deep well submersible pumps.

Stainless steel submersible deep well pumps are specially designed for use in seawater desalination, offshore, jack-up, floating dock, shipyard, vessel, salt water and clean water. A sea water submersible pump body set all is stainless steel material, like flange, impeller, pump body and other pump casting parts , testing report or testing video. Submersible pump for sea water has to be corrosive resistant, including SS304/SS316/SS316L /Duplex stainless/ Super stainless/SS904L or as per request.

Structural Characteristics and Operational Principle of Deep Well Submersible Pump:

Deep well submersible pump is an efficient and energy-saving water lifting tool for submersible work. 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 part 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.

 

 

Range of application:

Deep well bailing,agricultural irrigation,discharge of reservoirs or rivers, and water supply and drainage for special industries.

QJ type deep well submersible pump is a water lifting tool

The pump is not suitable for inflammable or explosive liquids.

 

Technology Parameters

Flow: 5-2500m3/h

Head: 12-600m

Rotary speed: 1450-2850r/min

Diameter: 100-800mm

Insulation class: B  

Protection grade: IP58

 

Working Conditions:

1. Three-phase power supply voltage deviation does 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 ℃.

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

 

Difference Between Cast Iron and Stainless Steel Submersible Pump:

1. In terms of performance, the performance of cast iron deep-well submersible pump is the same as that of stainless steel deep-well submersible pump. The difference is that the extraction medium is different. Stainless steel deep well submersible pumps can be well used in applications with corrosive media, such as seafood factories or seawater, including SS304 SS316 SS316L Duplex stainless steel and super stainless steel and SS904L.

2. In terms of price, cast iron deep well submersible pump has the greatest advantage. Because the greatest advantage of no embroidered steel deep well submersible pump is the application of saltwater, seawater or seafood factories, seawater desalination, offshore, jack-up, floating dock, shipyard.
