In the field of industrial fluid transportation, centrifugal pumps are widely used for their high efficiency and stability. With over 80% of industrial pumping systems relying on centrifugal pumps, ensuring proper selection is crucial to prevent costly downtime caused by overload failures. This article analyzes the causes of overloads and provides targeted solutions based on industry practices, helping enterprises optimize their selection processes and improve equipment reliability.

This is an article about how to avoid cavitation when purchasing centrifugal pumps, explaining the topic from multiple aspects. We believe you will gain significant insights after reading it!

The OH2 centrifugal pump belongs to the category of horizontal, single - stage, single - suction, overhung, and radially split volute pumps. It is mainly composed of components such as the pump body, impeller, pump shaft, bearings, and sealing devices. The pump body is supported at the centerline, which can effectively cope with thermal expansion and adapt to a temperature range from - 20°C to + 450°C, making it more adaptable than base - foot support. The impeller is mostly of a closed - type design with balance holes. Through advanced hydraulic design, it can balance the axial force and improve the cavitation performance simultaneously.

In industrial production, the sealing system of a pump is of great significance to the equipment. It is related to the operating efficiency and service life of the pump, as well as the safety and stability of the entire production system. There are numerous pump sealing methods, each with its own principles, application scenarios, and characteristics. The following is a detailed introduction to help you select a suitable solution.
