To continuously enhance the core competitiveness of its products, Hebei Ivy Pump Co., Ltd. recently completed a technological upgrade of its entire range of centrifugal pumps. This upgrade focused on optimising the mechanical seal water supply system and the materials of the flow-through components. After the upgrade, the average service life of the mechanical seals increased significantly from 3 months to 18 months, showing outstanding performance, particularly in supporting scenarios such as 700MW large power units. This technological innovation not only extended the product's fault-free operation time but also reduced the total lifecycle cost for end users, demonstrating the company's development philosophy of driving product upgrades through technological innovation.
