In industrial and high-rise water supply systems, Teffiko horizontal multistage centrifugal pumps are the core power source. However, many engineers find that the pump flow rate gradually "drops" after a period of operation and fails to reach the calibrated parameters. Combining the theoretical research of fluid machinery and frontline operation and maintenance experience, this article will thoroughly solve the problem of insufficient flow rate from three dimensions: tightness, system resistance and power source performance.

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 2026, driven by increasingly stringent global environmental regulations and the widespread adoption of Industry 4.0 smart manufacturing, Teffiko Sludge Screw Pumps (specifically Progressive Cavity Pumps) have evolved beyond their traditional role as auxiliary equipment in sewage treatment plants. Today, they stand as the core solution for transporting complex media across diverse industries.

In oilfield operations and industrial fluid transfer applications, Teffiko progressive cavity pumps (PCPs) are renowned for their exceptional capability in handling high-viscosity media. However, under complex operating conditions, these pumps may encounter malfunctions such as excessive vibration, overheating, or failure to discharge oil. By combining on-site operational data with an analysis of common faults, this guide systematically categorizes the causes of oil extraction issues in progressive cavity pumps and provides standardized solutions. This serves as a technical reference to ensure stable and efficient oilfield production.

Pipeline pumps and booster pumps, as indispensable core equipment in modern industrial, agricultural and civil water supply systems, are widely used in pressurization and water delivery scenarios due to their compact structure, convenient installation and maintenance, and stable and reliable performance. However, various faults are inevitable during long-term operation. Timely and accurate identification and resolution of these problems are of crucial significance for ensuring the stable operation of the system, extending the service life of the equipment and reducing operating costs. Combining the professional theories and practical experience of the Teffiko technical team, this paper deeply analyzes the seven most common faults of pipeline pumps and booster pumps, and provides detailed troubleshooting steps and efficient treatment methods, aiming to provide important reference for the majority of users.

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.
