product description

The biggest feature of the deep well pump is that the motor and the pump are integrated. It is a pump that is immersed in the groundwater well to pump and transport water. It is widely used in farmland drainage and irrigation, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. Because the motor is submerged into the water at the same time, the structural requirements for the motor are special than those of ordinary motors. The structure of the motor is divided into four types: dry type, semi-dry type, oil-filled type, and wet type.

Before starting the pump, the suction pipe and the pump must be filled with liquid. After the pump is turned on, the impeller rotates at high speed, and the liquid in it rotates together with the blades. Under the action of centrifugal force, it flies away from the impeller and shoots out. The speed of the injected liquid gradually slows down in the diffusion chamber of the pump casing, and the pressure gradually increases. Outlet, the discharge pipe flows out. At this time, a vacuum low-pressure area without air and liquid is formed at the center of the blade due to the liquid being thrown to the surroundings. The liquid in the liquid pool flows into the pump through the suction pipe under the action of the atmospheric pressure on the pool surface, and the liquid continues like this. It is continuously sucked up from the liquid pool and continuously flows out from the discharge pipe.

Basic parameters: including flow, head, pump speed, supporting power, rated current, efficiency, outlet diameter, etc.

Composition of submersible pump: It is composed of control cabinet, submersible cable, lifting pipe, submersible electric pump and submersible motor.

Scope of use: including mine rescue, construction drainage, agricultural drainage and irrigation, industrial water cycle, water supply for urban and rural residents, and even emergency rescue and disaster relief, etc.


1. The motor and the water pump are integrated, and the operation is submerged in water, which is safe and reliable.

2. There are no special requirements for well pipes and water pipes (that is, steel pipe wells, gray pipe wells, earth wells, etc. can be used; under pressure permitting, steel pipes, rubber pipes, plastic pipes, etc. can be used as water pipes).

3. It is convenient and simple to install, use and maintain, and occupies a small area without building a pump room.

4. The result is simple and saves raw materials. Whether the conditions of use of submersible pumps are suitable and properly managed are directly related to the service life.
