The VISO series end suction centrifugal pump adopts a rear pull structure, which eliminates the need to remove the pump body and pipelines during maintenance. The pump type only uses four types of pump shaft and suspension components, improving the interchangeability of parts. The impeller has been optimized for design, with an enlarged inlet diameter and no eddy currents, effectively reducing the pump’s NPSH and ensuring smooth and low noise operation. The pump body and cover both adopt a wear-resistant ring structure, which facilitates the maintenance of the water pump and improves the service life of the parts. The replaceable sealing ring ensures that the long-term operation of the water pump does not reduce efficiency.
