Centrifugal pumps and centrifugal compressors share a similar name and both operate on the powerful principle of centrifugal force, which is why many people often confuse them. However, as the title suggests, this single-word difference belies two entirely distinct pieces of equipment.

In the cutting-edge industrial fields handling liquefied natural gas (LNG), liquid nitrogen and ultra-low temperature chemical media, low-temperature chemical pumps have become the safety core of fluid conveying systems with their outstanding Italian engineering standards. As such equipment operates all year round under extreme working conditions ranging from -50 ℃ to -150 ℃, the structural integrity directly determines the stability of the production line.

If you are operating or designing a centrifugal pump system, NPSH (Net Positive Suction Head) is a term you simply cannot avoid. It is not just a physical parameter, but a critical dividing line that determines whether your pump will run smoothly for decades or be scrapped due to cavitation in just a few months.

In petrochemical plants, fluoroplastic centrifugal pumps are widely used to transfer highly corrosive media. Thanks to their unique lined structure, any slight abnormal noise may be a precursor to catastrophic equipment failure. As a technical expert at Teffiko, I will guide you to accurately identify the sub-healthy state of pump units by understanding the "language" of sound.

In the industrial fluid sector, Teffiko engineers emphasize a core principle: "A pump's stability is defined equally by its design and its foundation." The precision of foundation bolt installation directly dictates the natural frequency and vibration levels of a centrifugal pump during operation. Below are the six critical technical requirements for foundation bolt holes and grouting procedures, summarized by Teffiko's technical team for construction reference.

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.
