Horizontal Pump Leak-Proof Design

This article introduces high-temperature centrifugal pumps in oil refineries, covering their role in transporting 200-500℃ media, core differences from ordinary pumps, scientific selection based on medium parameters, and why TEFFIKO pumps are preferred with their expertise and full-life services.

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.

As a professional centrifugal pump brand, Teffiko has deep expertise in the industrial fluid transportation sector, with products widely applied across industries including water treatment, chemical engineering, HVAC and manufacturing. Amid upgraded industry energy efficiency standards and continuously evolving production operating conditions in 2026, centrifugal pump selection is no longer a simple matter of parameter matching—it directly impacts equipment energy consumption, operational stability and long-term operating costs. To help enterprises avoid procurement pitfalls, this document concisely outlines ten core selection factors tailored to current industrial procurement requirements.

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.

The impeller wear ring is an annular component installed between the impeller and the pump casing in equipment such as centrifugal pumps. It can reduce liquid leakage to improve efficiency, while protecting the impeller and pump casing and extending the service life of the equipment. It is used in centrifugal pumps and mixed-flow pumps in industries such as chemical engineering, water conservancy, and electric power.
