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 the intricate system of industrial production, fluid conveying equipment is like the blood vessels of the human body, maintaining the "life" of the entire production process. The stainless steel centrifugal pump, with its outstanding performance, has become the ideal choice for numerous critical scenarios. It can not only cope with various harsh working conditions with ease but also provides a reliable foundation for enterprises' stable production and cost control.

In chemical production, material transportation is a fundamental yet critical process. Twin-screw chemical pumps are widely used for conveying various liquid media due to their simple structure and stable operation. However, in practical applications, it has been observed that pump performance can vary with changes in the transported materials. Among these factors, viscosity plays a significant role.

The impeller wear ring is an annular component installed between the impeller and the pump casing in equipment such as centrifugal pumps. It can reduce liquid leakage to improve efficiency, while protecting the impeller and pump casing and extending the service life of the equipment. It is used in centrifugal pumps and mixed-flow pumps in industries such as chemical engineering, water conservancy, and electric power.

In high-risk industries such as chemical, pharmaceutical, and new energy, leakage from fluid transportation equipment not only causes material waste but also risks safety accidents and environmental pollution. Leak-free pumps, with their revolutionary sealing technologies, completely solve the leakage problems of traditional pumps. This article details the technical principles, application scenarios, and core differences of four major leak-free pump types—canned motor pumps, magnetic drive pumps, positive displacement diaphragm pumps, and electromagnetic pumps—providing a comprehensive selection reference for industrial fluid transportation.
