In various application scenarios such as petrochemical industry and industrial processes, split-case centrifugal pumps have become the preferred power equipment for many key systems due to their unique design and stable performance. This article provides a practical split-case centrifugal pump selection guide to help engineers, procurement decision-makers, and EPC contractors avoid common misunderstandings and select high-performance pump models that truly match project requirements.

In the petrochemical industry, pumps are an important part of fluid transfer, responsible for transporting crude oil, chemicals and other media. Once a pump breaks down suddenly, it is by no means a trivial matter: it may cause production interruption, leakage of hazardous media, or even downtime for several days, resulting in considerable losses. But do you really have to wait for a DCS alarm or the maintenance team to arrive to know that there is a problem with the pump? In fact, senior operators have relied on a "3-minute quick diagnosis method" for years—no complex tools are needed, only ears, eyes, hands and a little on-site experience. Below I will break it down step by step, presenting practical skills that even novices can easily master.

In the system of fluid conveying equipment, metering pumps are key devices with special functions. Unlike ordinary water pumps that only perform the basic function of fluid conveyance, metering pumps can precisely deliver fluids according to preset flow rates and speeds. Therefore, they are also called dosing pumps or proportioning pumps in industrial production and are widely used in scenarios requiring strict control of fluid dosage.

This article compares 10 core differences between double-suction & single-suction pumps, covering structure, performance, application, etc. It offers selection guidance. TEFFIKO, a pro pump enterprise, provides suitable, high-quality pumps for diverse needs, ensuring efficient operation.

Bearings are indispensable components in many mechanical devices, playing a vital role in reducing friction between moving parts. Two common bearing arrangements are Between Bearings (BB, double-supported) and Overhung (OH, cantilevered). These configurations each have distinct characteristics and suit different working conditions. Introduction

This article analyzes NPSH of chemical pumps, focusing on NPSHa & NPSHr differences. It covers their definitions, influencing factors, operational roles and matching tips, guiding pump selection, installation & maintenance to avoid cavitation and ensure stable operation.
