As a core lubrication component of machine tools, the lubrication effect of screw pumps directly determines the machining accuracy and service life of machine tools. Machine tool guideways are a lubrication difficulty—guideways move reciprocally with large changes in speed and load, which are prone to crawling and may even lead to machine tool scrapping in severe cases. To address this challenge, selecting a reliable lubrication system is particularly crucial. Teffiko, deeply engaged in the industrial chemical field, is committed to providing high-performance screw pumps. Combining practical experience and technical key points, this article sorts out the core requirements, difficulties and coping ideas of screw pump lubrication, providing a reference for operation and maintenance work and helping to achieve more efficient and stable lubrication management.

Damage to the magnetic pump isolation sleeve is a major safety hazard in chemical fluid transportation. Based on engineering practice, this article deeply analyzes the damage mechanisms of the isolation sleeve caused by hard particle wear, dry running lubrication failure, operating condition fluctuations, and cavitation, and provides professional-level prevention solutions to help improve the operational stability of magnetic pumps.

Self-priming pumps and centrifugal pumps are two common options, but many users still feel confused: what are the specific differences between them? Can they be used interchangeably? Which one is more suitable for low-liquid-level pumping scenarios? As an innovative brand focusing on high-efficiency pumping technology, Teffiko provides reliable selection support for industrial and municipal projects worldwide every year. This article will comprehensively analyze the essential differences between self-priming pumps and centrifugal pumps from the perspectives of working principles, structural differences, applicable working conditions, and practical operation and maintenance pain points, and provide scientific selection suggestions.

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.

In the field of industrial fluid transportation, multistage pipeline centrifugal pumps are widely used due to their advantages such as high head and small floor space. However, in actual operation, many engineers find that the pump performance (flow rate or pressure) fails to meet expectations. At this time, speed testing is often the primary step in troubleshooting. Let's explore the correct methods and common misunderstandings of speed testing for multistage pipeline centrifugal pumps with Teffiko to accurately identify the root cause of performance deviations.

Sludge screw pumps are widely used for their ability to transport high-viscosity media containing solid particles. However, during long-term operation, the equipment is inevitably prone to various faults or performance degradation. If not handled in a timely manner, it will not only affect system efficiency but also cause shutdown losses and even safety accidents. Based on Teffiko's years of R&D and practical experience in chemical screw pumps, this article deeply analyzes the seven most common problems of sludge screw pumps and provides a professional guide from root cause investigation to complete resolution.
