ISW series centrifugal pump is a pipeline centrifugal pump specifically designed for handling clean water or other media with physical and chemical properties similar to clean water. Its low-noise characteristics stem from optimizations in hydraulic design, motor configuration, and sealing components.
Generally speaking, the primary sources of noise in traditional centrifugal pumps are vortex noise generated by the impact between the impeller and volute, or friction, vibration, and leakage from bearings and seals, which further exacerbate energy waste. These losses result in the disadvantages of high noise, high wear, and low efficiency during the operation of traditional centrifugal pumps. ISW series vertical centrifugal pumps employ an advanced hydraulic model, redesigning the flow paths of the impeller and volute. This ensures fluid remains in contact with the blade surfaces, suppressing turbulent pulsations and vortex shedding, thereby significantly reducing the likelihood of fluid-induced noise. Furthermore, phase-shifted design self-cancels discharge pressure pulsations, preventing the pump casing from amplifying noise. Instead, residual energy is transferred downstream to enhance effective head.
In motor design, this pump eliminates traditional air-cooling fans by employing a water-cooled jacket encircling the stator and bearings, with coolant flowing through spiral water channels. This not only eliminates noise generated by air and fan losses but also significantly reduces motor operating temperature. Meanwhile, the pump employs a double-ended seal design, keeping the sealing surfaces lubricated to prevent noise and leakage caused by cavitation bursting. Moreover, its reliable sealing enables the equipment to maintain volumetric efficiency across a wider pressure range without requiring additional power compensation. ISW series vertical centrifugal pumps utilize high-efficiency motors in conjunction with variable frequency drives to eliminate traditional valve throttling losses. Their impellers feature a more flattened high-efficiency zone compared to previous designs, enabling the pumps to maintain near-peak efficiency even under partial load conditions. therefore, this series achieves high-efficiency operation across all operating conditions while significantly reducing energy consumption. ISW series centrifugal pipeline pump employs the above design and measures to reduce noise and energy consumption during operation. In other words, it can operate stably and quietly over extended periods without requiring additional soundproofing or cooling equipment, achieving both quiet and energy-efficient performance.
