The multi -stage pump is used to form a more powerful water flow in water supply systems that operate autonomously. It operates on the principle of operation of the wheel set sequentially. In such devices, the engine works quieter than in single-stage, and their cost is 2-3 times higher. They are great for houses in which more than one water intake is involved, while a large pressure is required.
Functioning
It operates due to the fact that a complex of working wheels works in it at the same time. The liquid that is passed through them is supplied to the pipe at times faster than through a device equipped with only one wheel. The final pressure depends on the stories of the wheels in total. They are placed sequentially, so they carry out the same feed. Pumps are equipped with 2-6 wheels.
Multi -stage pumping pumps of the Central History - horizontal, centrifugal. Designed for pumping fresh water with a temperature of up to +85 ° C, with a content of solid inclusions not exceeding a mass of 0.05% and the maximum size of 0.02 mm.
They have 2-4 working wheels. The spiral body of the pump has a horizontal connector. The supports of the pump rotor are bearings on oil lubricant. The seal of the shaft is saline. The shafts of the pump and the component of the electric engine are connected by the elastic bushing-plot coupling.
Advantages of multi -stage pumps
-
It sets a higher power motor;
-
The engine operation is completely silent;
-
At the least price, the optimal indicator of the efficiency is provided.
