The DL type vertical multi-stage centrifugal pump is a hydraulic model that adopts the recommended high-efficiency and energy-saving product IS type pump, and is a vertical multi-stage and multi-stage structure. The screw clamps and connects the inlet section, middle section, and outlet section into one. Each stage of the water pump is equipped with an impeller and a guide vane. The axial force is solved by hydraulic balance method, and the residual axial force is borne by the ball bearing and lubricated with grease. The shaft seal adopts soft packing or mechanical seal. The product complies with JB/T2727-93 "Types and Basic Parameters of Vertical Multistage Pumps" standard, mainly used for suction and delivery of diluted, clean, non corrosive, non explosive clean water and liquids with physical and chemical properties similar to water that do not contain solid particles or fibers. All of our products are designed and optimized using computers. Our company has strong technical strength, rich production experience, and comprehensive testing methods to ensure stable and reliable product quality.

Widely used in high-rise buildings for fire protection, factories, mines, oil fields, domestic water supply, as well as air conditioning unit circulation and cooling water transportation.

1. Advanced hydraulic model: high efficiency and wide performance range.
2. The multi-stage pump has a novel structure and reliable operation: it eliminates the balance drum and adopts hydraulic balance for axial force, completely solving the problems of corrosion, biting and wear of the balance drum, ensuring more reliable operation.
3. Less operating and maintenance costs: using high-quality mechanical seals, wear-resistant, leak free, long service life, low failure rate, with less operating and maintenance costs.
4. Smooth operation and low noise: Using a low-speed motor, the pump runs smoothly with lower noise.
5. Vertical structure, small footprint.

Clear water or solutions with physical and chemical properties similar to water below 90 ℃.
