The submersible pump is a water-lifting device composed of a submersible motor and a water pump. It is characterized by compact structure, convenient use and low price.

It has been widely used in agricultural irrigation and drainage, environmental protection, municipal engineering, water conservancy engineering, water supply and drainage in cities and industrial and mining enterprises, circulating water in industrial thermal power stations, dock lifting water level, water diversion engineering, drought resistance, etc.

Characteristics of hydraulic submersible pumps

1. The submersible pump adopts the direct connection between the water pump and the motor, and the small submersible pump even installs the water pump impeller directly on the motor shaft, which saves many connected parts, shortens the overall size of the pump, reduces material consumption, and reduces weight. When replacing the deep well pump, the problem of high failure rate of the long shaft is reduced, and the reliability of the equipment is improved.

1. Simple installation, no need to build a pump house, small civil construction area, reducing infrastructure investment, and the submersible pump directly submerges into the water, only the ground construction of electrical control equipment is required, and it is easy to use and maintain.

1. It has low noise in underwater operation, and is very suitable for places where a quiet working environment is required, such as water supply and drainage in schools, hospitals, hotels, halls, etc.

1. The submersible pump operates underwater and is not affected by the climate and surrounding working environment; it is convenient for concealment and suitable for combat readiness and strategy.

1. Using the submersible pump to lift water, the depth of water lifting is increased, and the problem of cavitation is less.

1. The built-in submersible motor can ensure that the dry motor submersible pump runs for a long time even if it is close to draining the water absorption pool, and there is no need to worry about the problem of the motor heating up and burning due to the large no-load current.

1. The submersible pump may cause problems such as leakage of electricity, water ingress of cables, leakage of mechanical seals and failure of other static seal components, which may cause the whole pump to burn out or leakage accidents.

The difference between hydraulic submersible pump and sewage pump

Different media handled

Generally, the water quality of sewage pump treatment is relatively poor. The water quality may contain high corrosiveness and the conveying medium is a medium containing solid particles such as fibers and paper scraps in feces or liquid. The conveyed medium contains fibrous materials that are easily entangled or bunched. ; The working conditions of the submersible pump are relatively simple, and the conveyed medium is mainly clean water, which is easier to choose than the sewage pump for the material requirements of the product.

Different structure

Because of the differences in the media they handle, there are differences between sewage pumps and submersible pumps. Sewage pumps need technology to deal with the medium of long fibers, paper scraps and other solid particles, so blocking resistance and reliability are important factors for the quality of sewage pumps; and Compared with sewage pumps, submersible pumps have a much simpler structure.

Different application

Sewage pumps are used in sewage transportation/discharge, sponge city, conveying industrial wastewater, pumping station drainage, urban flood prevention and discharge, etc.; while submersible pumps are used in deep well water intake, irrigation, offshore platforms and other fields.
