Superior Casting & Surface Treatment
- Pump body castings undergo silicate gel pickling and passivation, eliminating sand holes for a smoother surface.
- Result: 10% increase in pump efficiency.
Advanced Magnetic Drive System
- - Unique poly-magnetic & combination push-pull magnetic circuit design.
- Benefits: Compact size, high power, minimal eddy current losses, high efficiency, zero slippage, and exceptional reliability.
- Inner/outer rotor magnetic steel ensures rated torque transmission with a safety margin based on rare earth permanent magnet demagnetization rates.
- Lifespan: Magnetic steel designed for 15–20 years of service.
Axial Force Self-Balancing Technology
- Patented axial force balance structure achieves near-zero axial force at operational points.
- Advantage: Enhances system stability during operation.
Optimized Bearing Structure
- Sliding bearings ensure smooth operation and optimal lubrication.
- Thermal assembly anti-rotation design reduces vibration and extends bearing life.
Intermediate Support & Pressure-Bearing Isolation Sleeve
- Tungsten carbide bearings maintain concentricity and resist thermal expansion.
- Self-lubricating material allows short-term dry running capability.
High-Performance Magnetic Material
- NdFeB (neodymium-iron-boron) magnets with 380–450 Gauss surface intensity.
- No demagnetization during operation, suitable for media with specific gravity 1.2–2.
- Outcome: Extended lifespan and superior stability.
