TEFFIKO announces its participation in the 21st OGA Asian Oil & Gas Exhibition to be held in Kuala Lumpur from September 2 to 4, 2025, inviting professionals to explore cooperation.

Low flow rate in centrifugal pumps? Understand the root causes of flow reduction, capacity‑expansion solutions and safety risks, and select appropriate methods to boost the capacity of industrial centrifugal pumps.

TEFFIKO, with over 20 years of experience in industrial pump R&D and manufacturing, has accumulated extensive practical project experience for high‑pressure feed‑water operating conditions. Below is a plain‑language explanation of the basic concepts and operating principles of boiler feed water pumps.

At chemical, electroplating, pharmaceutical and sewage treatment sites, pump failures seldom occur abruptly. They start with liquid seepage at seals, followed by impeller jamming by crystalline deposits, and later corrosion perforation of pump casings.

The mechanical seal face is the most vulnerable core component of centrifugal pumps. Subject to high temperatures, medium crystallization, environmental impurities and other factors, it is highly prone to failures such as abrasive leakage and thermal cracking. Seal‑face quenching is a critical protection process for water pumps. By injecting liquid or gas into the low‑pressure seal face, it achieves rapid cooling, impurity isolation, debris removal and containment of leaked media. It constitutes an indispensable operation‑and‑maintenance measure under special working conditions. Teffiko has long been dedicated to centrifugal‑pump mechanical‑seal solutions. This article concisely outlines the core scenarios and application specifications for activating face quenching, catering to daily equipment operation and maintenance requirements.

Teffiko insulated magnetic drive pumps combine the zero‑leakage, seal‑free advantages of magnetic drive pumps with jacket temperature‑control structures. They can be heated by steam or thermal oil or cooled by refrigerant to stabilize the temperature of the pumped media, preventing issues such as medium solidification, crystallization, cavitation and sharp viscosity increase. Many process engineers in chemical, petrochemical, pharmaceutical and rubber‑plastic industries often ask: what media require the use of insulated magnetic drive pumps? This article sorts media by their characteristics to help you make quick and accurate pump selection.
