*The pump hydraulic model is from Europe with high efficiency. Two sets of hydraulic model is equipped at same outlet port. The flow range at BEP best efficiency point is wide, and NPSHr is low only 0.5m.
*The pump is double casing multi-stage section ring type with less sealing points.
*Leakage-free is realized by static sealing gasket for all the sealing points and magnetic coupling driven. The nitrogen sealing is also not used, so the operation of pump is safe, economic and reliable.
The modular theory design makes compact structure, parts generalization and easy maintenance.
*The pump standard confirms to GB3215 and API685.
*The containment shell is made from Hastelloy formed by special technology without axial welding seam. So it ensures the sealing and chemical stability for the containment shell.
*The double layer of containment shell functions reliable double protection. It will be alarmed when the first layer of containment shell is leaked while the liquid is still completely sealed without any leakage.
*The magnet material is made of special rare earth alloy with demagnetizing temperature up to 450 Degrees Celsius through special technology. So the pumps are guaranteed 15 years of operation life;

*The slide bearing material is high purity of 99% silicon carbide, and all the friction couples of bearing are high quality silicon carbide.
*The axial thrust balancing is important for magnetic drive pumps. Our pump is automatically balanced the axial thrust in hydraulics principle. *The thrust ring of slide bearing only bears the unbalanced axial

 thrust when pump is stopping or starting. So the slide bearings operation life is guaranteed.
*Whole set of protection instrument such as running protector, leakage detector etc. Are equipped.
Material:

Containment shell
The containment shell is made from Hastelloy c-276 formed by special technology without axial welding seam. So it ensures the sealing and chemical stability for containment shell
The double layer of containment shell functions reliable double protection. It will be alarmed when the first layer of containment shell is leaked while the medium is still completely sealed without any leakage.
Slide bearing
The material of slide bearing is made from 97.5% purity rate of silicon carbide (SSIC),The working life of the wear resisting and high strength material is 10 times of normal silicon carbide baring and carbon bearing.
Ball bearing
The ball bearing is NSK or SKF bearings.
Lubrication: Grease or Oil, It depends the customer's request.
Magnetic material
The magnet material of Kehuan magnetic pump is permanent-magnet alloy with unidirectional temperature up to 450^oc. It is a medium to pass on the moment of torsion in magnetic driven pump. It guaranteed a wide 

operating range and is highly resistant against demagnetization.
