Multi stage pump

The design of multi-stage pumps mainly adopts a balance drum, a balance drum sleeve, and a balance water pipe device to balance axial forces. A protruding sealing ring structure and a balance hole are added to the rear cover plate of each impeller section to achieve the goal of balancing most of the axial forces. The new structure of the vertical multi-stage pump mainly manufactured and produced by Shanghai Meiyanyi Pump Valve is simpler than the existing general multi-stage centrifugal pump, reducing the volume and weight of the pump, and achieving good balance effect, high reliability of operation, and avoiding the possibility of corrosion caused by long-term non operation of the pump. The horizontal multi-stage pump joint balancing device produced by Shanghai Meiyan Yi Pump Valve involves a joint balancing device that balances the axial force between the pump shaft and the body, eliminating the axial thrust of the pump rotor. The clearance between the balance plate and the balance ring is optimal, improving the reliability and service life of the water pump. Shanghai Meiyanyi Pump Valve is one of the main manufacturers of multi-stage pumps in China. The vertical multi-stage pumps produced are mainly suitable for the water supply field, mainly used to increase water pressure to meet the water pressure needs of high-rise buildings, industrial equipment, municipal engineering, etc. In urban water supply systems, multi-stage pumps are often used as the main equipment of central water pumping stations to ensure stable pressure of drinking water for urban residents. Horizontal multi-stage pumps are widely used in the industrial field, commonly used for conveying liquid media, water supply, high-pressure water injection, cooling circulation, and other aspects. For example, multi-stage pumps are important equipment in industrial enterprises such as refineries, smelters, power plants, and paper mills.
