summary

The water supply booster pump for high-rise buildings is a vertical single suction multi-stage segmented centrifugal pump, which is installed vertically. The motor shaft is connected to the pump shaft through a claw type coupling, and its suction and discharge ports are located on the inlet and outlet sections respectively. The rotor component consists of shaft, impeller, impeller guard sleeve, shaft sleeve and other parts, and the inlet section, middle section, and outlet section are connected with tension bolts. The shaft seal adopts soft packing seal or mechanical seal, and is lubricated and cooled with pressure water from the balance chamber. It has the advantages of compact structure, low noise, and small footprint, and is particularly suitable for supporting pumps for constant pressure water supply, fire protection, and sprinkler water supply equipment in high-rise buildings such as residential buildings, hotels, and office buildings; Also suitable for automatic water replenishment of cooling towers in chemical processes; Used for water supply equipment such as system stabilization, production process circulation water, long-distance transportation, and boiler water supply. The liquid that can be transported is room temperature (<80 ℃) (hot water type can transport medium with a temperature less than 105 degrees), clean water, or room temperature medium with physical and chemical properties similar to water. The product complies with the JB/T2727-93 "Types and Basic Parameters of Vertical Multi stage Simple Centrifugal Pumps" standard.

Advantages of use

1. Low pump cost: By using a high-speed motor, this series of pumps has the characteristics of light weight, small size, and low cost. If equipped with a protective cover, they can be used outdoors.

2. Fewer operating and maintenance costs: Using reliable mechanical seals, low failure rate, and lower operating and maintenance costs.

3. Adopting a detachable structure, it facilitates the replacement of vulnerable parts such as mechanical seals by users, facilitates installation and maintenance, and does not require dismantling of pipeline systems. The inlet and outlet of the pump have the same diameter, simplifying the connection of the pipeline.

4. The booster pump for water supply in high-rise buildings can be operated in series or parallel according to the flow rate and head requirements.

5. According to the needs, the inlet and outlet can be installed in the same direction or in different directions such as 90 °, 180 °, and 270 ° to meet different connection scenarios.

6. The pump head can be increased or decreased according to the needs of the pump stage and combined with cutting the outer diameter of the impeller to meet the requirements, without changing the installation footprint,

7. Novel structure and reliable operation: The balance drum (disc) has been removed, and its axial force adopts hydraulic balance, solving the problems of easy rusting, biting, and wear of the balance drum, ensuring more reliable operation.

8. Excellent components, noise reduction: Excellent hydraulic component design, excellent flow performance, greatly reducing flow noise.
