The vertical multi-stage centrifugal pump is a hydraulic model of the IS-type pump of the high-efficiency energy-saving product recommended by the state, and is a vertical multi-stage multi-segment structure. The screw clamps the inlet section, the middle section and the outlet section into one body. Each stage of the pump is equipped with an impeller and a water guide vane. The axial force is solved by the hydraulic balance method, and the residual axial force is received by the ball bearing and lubricated with grease. The shaft seal is made of soft packing or mechanical seal. The product implements JB/T2727-93 "Vertical multistage centrifugal pump type and basic parameters" standard, mainly for sucking diluted, clean, non-corrosive, non-explosive clean water and physicochemical properties similar to water without solid particles Or a liquid of fiber. The company's multi-stage pumps are all designed and optimized by computer. The company has strong technical strength, rich production experience and perfect testing methods to ensure stable and reliable product quality.
Advanced hydraulic model: high efficiency and wide performance range.
The structure is novel and the operation is reliable: the balance drum is eliminated, and the axial force is hydraulically balanced, which completely solves the problem that the balance drum is easy to rust, easy to bite and easy to wear, and the operation is more reliable.
Less operation and maintenance costs: high quality mechanical seal, wear resistance, no leakage, long service life, low failure rate and less operation and maintenance costs.
Smooth operation and low noise: The low-speed motor is used to make the pump run smoothly and the noise is lower.
Vertical structure, small footprint.
