summary
Vertical multi-stage pipeline centrifugal pump is a product designed and manufactured based on high-quality pump models abroad, combined with user requirements and fire protection standards, and in accordance with JB/TQ6435-92 standard. The suction and discharge ports of the water pump are located in the same straight line. 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 a mechanical seal, which is lubricated and cooled with pressure water from the balance chamber. It is a pump type suitable for conveying cold and hot water or liquids with physical and chemical properties similar to water in various industries. Widely used in the circulation and pressurization of cold and hot water in high-pressure operating systems, parallel water supply by multiple pumps in high-rise buildings, fire protection, boiler water supply and cooling water systems, and the transportation of various flushing liquids.
characteristic
1. Hydraulic model: high efficiency and wide performance range.
2. Easy installation and maintenance: Pipeline installation and inlet and outlet can be installed in any position and direction of the pipeline like valves, making installation and maintenance extremely convenient.
3. Beautiful appearance: The vertical multi-stage pipeline centrifugal pump adopts a high-quality stainless steel jacket, which has a beautiful appearance.
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. Reasonable components and noise reduction: Reasonable hydraulic component design, good flow performance, greatly reducing flow noise.
6. Vertical structure with small footprint., The center of gravity of the pump coincides with the center of the pump foot, resulting in smooth operation, low vibration, and long service life.
