API OH2 Performance Test Data

Centrifugal pumps dominate industrial fluid transport for efficiency and stability. This guide uses a 3-step method—media analysis → parameter matching → structural optimization—to streamline pump selection.

In the installation and operation of a centrifugal pump, the foot valve at the water inlet, though seemingly simple in structure, is a key component ensuring the stable operation of the pump unit. Many users only know that a foot valve must be installed at the water inlet of a centrifugal pump, yet they are unclear about its core functions. This article will explain in detail why the foot valve is absolutely essential.

If you work with industrial centrifugal pumps regularly, you’ve probably come across the “OH1” model—and let’s be honest, it’s really easy to mix up with other types. Many engineers know centrifugal pumps transport fluids, but if you ask them what makes an OH1 pump unique? Most of them will struggle to answer. And don’t even get me started on procurement teams—misunderstanding the model all but guarantees ending up with the wrong equipment. But here’s the thing: OH1 pumps are workhorses in industries like oil, power, and chemicals. They’re a classic overhung pump under the API 610 standard (the global design code for centrifugal pumps), and once you get the basics down, they’re actually pretty straightforward. Let me walk you through the key details.

Global petrochemical industry accelerates equipment upgrades, API centrifugal pumps become key driving force As the global energy industry's demand for safety and sustainability increases, high-performance centrifugal pumps that meet the standards of the American Petroleum Institute (API) have become a hot spot in the industrial field. Recently, a new generation of API 610 standard centrifugal pump series has been launched and has been adopted by a large refinery in the Middle East and a shale gas mining company in North America. It is expected to reduce the equipment failure rate by more than 30%.

As a core lubrication component of machine tools, the lubrication effect of screw pumps directly determines the machining accuracy and service life of machine tools. Machine tool guideways are a lubrication difficulty—guideways move reciprocally with large changes in speed and load, which are prone to crawling and may even lead to machine tool scrapping in severe cases. To address this challenge, selecting a reliable lubrication system is particularly crucial. Teffiko, deeply engaged in the industrial chemical field, is committed to providing high-performance screw pumps. Combining practical experience and technical key points, this article sorts out the core requirements, difficulties and coping ideas of screw pump lubrication, providing a reference for operation and maintenance work and helping to achieve more efficient and stable lubrication management.

This article focuses on metal wound gaskets for chemical pumps, explaining their basic characteristics, selection points, sealing coefficients, installation and maintenance. It emphasizes the importance of suitable gaskets for pump safety and introduces TEFFIKO's professional solutions.
