Circulatory convection, multi-stage pressure reducing mechanism, avoide cavitation efficiently, prolong service life.
All the trims can be quickly removed and replaced, easy to maintain with less cost.
Imported high-quality stem packing ensures leak-free without frequent replacement.
Scientific construction, high-performance materials and exquisite workmanship enable both the plug and cage to have excellent anti-blocking and anti-seizure performance so that a small amount of sundries in the pipeline will not lead to any blocking for the passage now seizure for the plug in condition of frequent opening.
Appropriately matched plug and cage materials provide an excellent resistance for abrasion, scratching and seizure.
Zero leakage, long-service life and low breakdown rate ensure a safe and reliable operation of the feedwater pump.
