In industrial wastewater treatment, municipal sewage systems, and circulating water systems, vertical turbine pumps serve as core power equipment responsible for transporting complex media containing solid particles, fibers, and sediments. However, impurities in the media often lead to pump clogging…
The Hidden Cost of Seal Failures in Vertical Turbine Pumps Mechanical seal failure is one of the most critical operational challenges for any vertical turbine pump. Due to deep-well designs where shaft lengths can extend tens of meters, traditional split…
The vertical lineshaft turbine pump is essential in water supply, agriculture, power plants, and industrial applications. While known for its robust construction and long service life, one of its most common points of failure is the mechanical seal. In fact, mechanical seal…
Why Solids in Fluids Pose a Serious Risk to Vertical Turbine Pumps In demanding industries like mining, dredging, and wastewater treatment, vertical turbine pumps often process liquids containing abrasive solids such as sand, slag, or fibrous material. These seemingly minor…
In multistage vertical turbine pump applications, impeller trimming is a commonly used method for adjusting pump performance to better align with actual system requirements. It involves reducing the impeller diameter to decrease the amount of energy imparted to the pumped fluid.…
Cavitation is a hidden threat to the reliable operation of vertical turbine pumps, leading to vibration, noise, and impeller erosion, which can ultimately cause catastrophic failures. Due to their unique structure—long shafts often reaching tens of meters—and complex installation, determining…
In multistage vertical turbine pump systems, the impeller gap—defined as the radial clearance between the impeller and the pump casing or guide vane ring—plays a critical role in determining the pump’s efficiency and reliability. Typically ranging between 0.2 mm and…
Multistage vertical turbine pumps are widely used in critical applications such as industrial cooling, water supply, chemical processing, and deep-well pumping. Ensuring the mechanical stability of these pumps over long operational periods requires careful management of axial and radial forces…
The split case double suction pump is widely used in large-scale fluid transport applications due to its high efficiency, stable performance, and balanced axial thrust. To ensure that the pump meets performance standards and design requirements before commissioning, a complete…
Performance adjustment of a split case double suction pump is a systematic process of evaluating and modifying key operational parameters to meet specific application requirements. Proper adjustment ensures efficient operation under varying system conditions, reduces wear, and extends pump life.…
