Vertical Multistage Pump - High-Efficiency Pressure Boosting Solution

The Vertical Multistage Pump is an advanced pumping system designed to deliver high-pressure performance in a compact, space-saving design. Ideal for water supply systems, industrial processes, boiler feed applications, and irrigation, these pumps combine multiple impellers in a vertical configuration to achieve pressure capabilities while maintaining energy efficiency.

How Vertical Multistage Pumps Work

The seal of the multistage vertical centrifugal pump is a mechanical seal, which is cooled and lubricated by the pressure water in the balance chamber. The water inlet section, the middle section and the water outlet section of the parts are fastened by tie rods. When the impeller on the multistage centrifugal pump motor drive shaft rotates at high speed, the liquid filled in the impeller is under the action of centrifugal force.
From the center of the impeller along the flow channel between the blades to the surroundings of the impeller, the liquid is affected by the blades, so that the pressure and speed increase at the same time, and it is guided to the next level of impeller through the flow channel of the guide shell. It is this principle that makes it flow through all impellers and guide shells in turn, further increasing the pressure energy of the liquid.
After gradually stacking each impeller, a certain head is obtained. The multistage vertical centrifugal pump is composed of the pump body rotor part and the motor. The rotor part consists of the pump shaft, impeller, sleeve, impeller stop sleeve, etc.
