API OH1 Pump Technical Datasheet

Screw pumps have the following advantages: Can transport high-viscosity media, suitable for occasions where viscous media are transported; Due to its simple structure, it is easy to maintain;

Screw pumps are one of the oldest and most reliable positive displacement pump technologies in the industrial fluid handling sector. Their full product range, including single-screw, twin-screw, and triple-screw pumps, is widely used in oil and gas, chemical, marine, and other industries. These pumps have gained global customer recognition for their reliable performance and customized solutions. Despite their simple structure, many engineers lack a thorough understanding of their working principle and selection applications. This article provides a detailed explanation based on TEFFIKO engineering practice to support equipment selection decisions and maximize the optimal performance of screw pumps.

Repair Methods for Impellers of Chemical Centrifugal Pumps": Outlines 4 damage types (corrosion, erosion, etc.), 4 repair methods (welding, coating, etc.) & key points, notes material compatibility & dynamic balance, with FAQs to aid repair selection.

In industrial production, the safe transportation of corrosive media has always been a technical difficulty. Such media are prone to corrode equipment, affecting production efficiency and safety. However, fluoroplastic magnetic pumps, with their unique design and material advantages, have become an ideal solution to this problem and are widely used in chemical, pharmaceutical and other fields.

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 petrochemical, water supply systems, heating, ventilation, and industrial processes, pipeline centrifugal pumps are key equipment ensuring the stable transportation of fluids. However, many on-site engineers often encounter a typical problem: "The pump is obviously running, so why is the water output significantly reduced, or even failing to pump water at all?" This not only affects production efficiency but may also trigger chain failures such as cavitation and motor overload. Combining fluid mechanics analysis by senior researchers and practical experience from frontline operation and maintenance, this article will deeply dissect the five core dimensions leading to the performance degradation of pipeline centrifugal pumps.
