summary

The high lift vertical multi-stage pump is a vertical multi-stage multi segment structure, manufactured using the hydraulic model of the highly efficient and energy-saving product IS pump recommended by the country. The screw clamps the inlet section, middle section, and outlet section together. Each stage of the water pump is equipped with an impeller and guide vanes. The axial force is solved by hydraulic balance method, and the residual axial force is borne by the ball shaft bearing and lubricated with grease. The shaft seal adopts soft packing or mechanical seal. The product complies with the JB/T2727-93 "Types and Basic Parameters of Vertical Multi stage Centrifugal Pumps" standard, mainly used for suction and delivery of diluted, clean, non explosive clean water and liquids with physical and chemical properties similar to water without solid particles or fibers. Widely used in high-rise buildings for fire protection, domestic water supply, air conditioning unit circulation, and cooling water transportation. The operating temperature of the medium shall not exceed 80 ℃, and the operating temperature of the DIR type medium shall not exceed 120 ℃.

characteristic

1. Vertical structure with small footprint.

2. Hydraulic model: high efficiency and wide performance range.

3. Smooth operation and low noise: Using a low-speed motor to ensure smooth pump operation and lower noise.

4. Less operating and maintenance costs: Adopting high-quality mechanical seals, it is wear-resistant, leak free, has a long service life, low failure rate, and has lower operating and maintenance costs.

5. Novel structure and reliable operation: The balance drum has been removed, and its axial force adopts hydraulic balance, which solves the problems of easy rusting, biting, and wear of the balance drum, ensuring more reliable operation.
