Energy Efficiency & Performance
Advanced CFD-optimized hydraulic models for pump body, pump cover, and impeller ensure maximum hydraulic efficiency. Resin-sand molding provides precise dimensions and smooth flow channel surfaces.
Welded impeller construction delivers superior dimensional accuracy, geometric precision, and extended service life compared to traditional casting methods.
Innovative back-to-back impeller arrangement effectively balances axial forces, while double-suction impeller design eliminates axial force generation in final stages.
Double-volute casing structure and symmetrical transition flow passages maintain hydraulic balance and prevent wear from vortex formation.
Patented seal ring technology with dual O-ring seals and radial protrusions provides superior erosion protection and extended component life.
Intellectual Property
This product features multiple patented technologies, including the innovative seal ring design granted a Utility Model Patent Certificate by the National Intellectual Property Administration.
