API OH1 Pump Performance Data

Last week, Teffiko made its appearance at the Oil and Gas Asia (OGA) exhibition held in Malaysia. During the exhibition, its booth attracted a large number of existing and new customers, and finally achieved remarkable results, further consolidating its position in the industry.

In the design, selection, and performance evaluation of centrifugal pumps, there is a seemingly abstract yet crucial concept—specific speed. It serves not only as the "fingerprint" for distinguishing the hydraulic characteristics of different pumps but also as a key bridge connecting theoretical fluid mechanics with engineering practice. So, what exactly is the specific speed of a centrifugal pump? Where does it originate? And how does it affect the actual operation of the pump? This article will comprehensively explain this core parameter by combining hydraulic similarity laws with engineering applications.

In the energy conversion process of a centrifugal pump, not all input power can be effectively converted into the pressure energy and kinetic energy of the liquid. In actual operation, inevitable energy loss always exists. According to the physical mechanism of energy loss, the loss of a centrifugal pump is usually divided into three categories: Hydraulic Loss, Volumetric Loss and Mechanical Loss. These three types of loss jointly determine the overall efficiency of the pump.

Having worked in chemical plants for more than ten years, I have seen too many cases of midnight rush repairs and production shutdowns for rectification due to wrong pump selection. Especially for API OH3 vertical chemical process pumps, many people think: "It's just a pump; as long as the flow rate is sufficient and the head meets the standard, it's fine." But the reality is that the operating conditions are much more complex. Today, combining the mistakes I've made and the problems I've helped customers solve, I'll talk about how to choose a truly reliable API OH3 pump for your factory.

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.

In the selection and application of screw pumps, TEFFIKO has always been committed to providing solutions that fit actual working conditions. Both single screw pumps and twin screw pumps can meet diverse conveying needs with their unique performances. To help customers make selections, TEFFIKO elaborates on the following aspects of core differences and application ranges:
