Corrosion-resistant and wear-resistant multi-stage pumps are crucial equipment widely used in chemical, pharmaceutical, and metallurgical industries. Their primary function is to transport liquids from a lower to a higher position. Due to their specific working environments, these multi-stage pumps have some vulnerable parts. Below are some of the main vulnerable parts and their characteristics.

1. Mechanical seals: This is one of the important components of a multi-stage pump, mainly used to prevent liquid leakage between the pump shaft and the casing. Due to the pump's operation and the corrosive nature of the transported medium, mechanical seals are easily subject to wear and corrosion, making them a vulnerable component.

2. Bearings: Bearings support the pump shaft rotation. Due to prolonged operation and corrosion/wear from the medium, bearings usually require periodic replacement.

3. Impeller: The impeller is the core component of the pump, responsible for liquid transport. Due to solid particles, corrosiveness, and wear in the medium, the impeller surface is easily damaged and requires regular inspection and replacement.

4. Inlet and outlet valves: The inlet and outlet valves of a multi-stage pump are easily subject to wear and corrosion during the switching process. The valve's lifespan is affected, especially with frequent switching or large fluctuations in medium pressure.

5. Sealing rings and guide vanes: These components guide liquid flow and seal the pump chamber. Due to prolonged exposure to the impact and corrosion of liquids, they are prone to wear and aging.

6. Balancing disc and balancing sleeve: The balancing disc and balancing sleeve in a multi-stage pump balance the axial force of the pump. Due to vibration and impact during operation, these components are also prone to wear.

7. Nuts, bolts, and other fasteners: During the operation of a multi-stage pump, nuts, bolts, and other fasteners are prone to loosening or breakage due to vibration and loss of clamping force.

To ensure the normal operation and extend the service life of corrosion-resistant and wear-resistant multi-stage pumps, in addition to selecting suitable materials, regular inspection and maintenance of vulnerable parts are also necessary. Once wear or damage is found, the parts should be replaced promptly to avoid greater losses caused by continued operation with the problem. Choosing reputable manufacturers and suppliers to ensure the reliability of purchased parts is also crucial for the normal operation of the multi-stage pump. In short, proper maintenance of corrosion-resistant and wear-resistant multi-stage pumps ensures efficient and stable operation and extends their service life.
