The DL-type vertical multistage centrifugal pump adopts a vertical multistage multi-section structure. The water inlet section, middle section, and water outlet section are clamped and connected into one body by screws. Each stage of the pump is equipped with an impeller and a guide vane. The axial force is solved by the hydraulic balance method, and the residual axial force is borne by the ball shaft bearing, which is lubricated with grease. The shaft seal adopts soft packing or mechanical seal. It is mainly used to suck and transport diluted, clean, non-corrosive, non-explosive clear water and liquids with physical and chemical properties similar to water that do not contain solid particles or fibers.

Features
1.Hydraulic model optimization: High efficiency and wide performance range.
2.Novel structure and reliable operation: The balance drum is eliminated, and the axial force is balanced hydraulically, completely solving the problems of easy rust, seizure, and wear of the balance drum, ensuring more reliable operation.
3.Lower operation and maintenance costs: Adopting high-quality mechanical seals with wear resistance, no leakage, long service life, and low failure rate, resulting in fewer operation and maintenance expenses.
4.Stable operation and low noise: Using low-speed motors makes the pump run smoothly with lower noise.
5.Vertical structure with a small footprint.
