Introduction of self-priming centrifugal pump and submersible pump

Date of release:2018-10-26 Author: Click:

Self-priming pump is a single-stage single-suction centrifugal pump, which is called self-priming centrifugal pump, which depends on the special structure of the pump itself. 

Compared with the ordinary centrifugal pump, there are significant differences in the structure of the pump body: first, the inlet position of the pump is improved, and sometimes the suction valve is installed; second, a gas-water separation chamber is set up on the outlet side. 

Pump external self-priming pump, is in the pump with self-priming device, such as with vortex pump, water ring vacuum pump, jet pump and manual pump and so on. 

Compared with the ordinary centrifugal pump, the self-priming pump has the advantages of compact structure and simple operation, which not only saves the trouble of pumping a large amount of water before starting, but also saves the low valve of the intake pipe, reduces the inlet resistance and increases the output of the pump. 

However, the efficiency of the ordinary centrifugal pump of the same size is 3% to 5% lower than that of the ordinary centrifugal pump of the same specification。 

Self-priming pump is widely used in light and small sprinkler irrigation units and pipeline irrigation units. 

Maglev submersible pump has achieved a major breakthrough in the field of submersible pump in the world, and effectively solved the disadvantages of traditional submersible pump, such as low conversion efficiency, high power consumption, limited head, easy bearing damage, frequent maintenance and so on. 

It is widely used in the fields of water supply and drainage, farmland irrigation, plateau and mountain water supply in industrial and mining enterprises。 

Magnetic levitation submersible pump has changed the manufacturing process of submersible pump with unique patented technology, the conversion efficiency has reached a shocking new level, and created a huge benefit of energy saving and consumption reduction. 

The magnetic levitation submersible pump has solved the problem of axial force restricting the development of the submersible pump in the world, and the lift of the submersible pump has been improved through a breakthrough。 

It fills the market gap of ultra-high lift (single head design to thousands of meters) and super-large flow (high load) submersible pump; the lift and flow curve tends to be smooth. 

Its conversion efficiency and the highest head of a single machine are in the leading position in the world。 

Magnetic levitation submersible pump is a new generation of submersible pump, which realizes vertical shaft maglev (keeping high efficiency under different working conditions), no wear, several times longer service time and maintenance period, and saves frequent regular maintenance work. 

Can run continuously for tens of thousands of hours, saving maintenance, maintenance costs. 

Maglev submersible pump has passed the national laboratory, Shandong pump product quality testing center. 

The test data show that the conversion efficiency of the maglev submersible pump is higher than that of the traditional submersible pump, and the use of the user is combined with the experimental data and the comparison in the field. 

It is further proved that it has the characteristics of high efficiency and energy saving, world leading conversion efficiency, world leading single head and high load bearing, super large flow, no maintenance, long life and so on!
