Foot-mounted structure or Center line supported structure.
The pump and motor are separated with standard normal motor, so the pump can be changed parts at site and needs not be returned factory.
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.
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 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 pump standard confirms to API 610, API 685 etc.
Material:
Carbonsteel; chromed steel; austeniticstainlesssteel; duplexsteel; Titanium and Titanium Alloys; Hastelloy C-276 and other special materials; It depends the customer's request.

The containment shell is made fromHastelloy c-276formed 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 450oc. 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.
