Structural features:

• single-stage, single-suction, cantilever structure.

• The pump casing can be increased according to the needs of insulation jacket structure.

• Medium temperature within 250 ºC does not require any cooling measures, higher than 250 ºC need to increase the cooling facilities; the maximum operating temperature up to450 ºC.

• Foot-mounted structure or centerline 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 pumps are outfitted with a heat jacket and pump casing and/or a heat jacket in the bearing housing . The heat jackets can also be used for cooling.

Applications:
Horizontal installation, suitable for conveying hazardous, corrosive, toxic, flammable, expensive, easy to vaporize and volatile media.
Magnetic drive sealless pumps offer significant advantages and benefits over conventional sealed designs:
No seals
No seal support systems
Complete fluid containment
Zero emissions
Zero contamination of pumped liquid
Cost effective installation
No ancillary seal support systems to specify and install
Longer mean time between failure (MTBF)
No EPA monitoring required
Improved operator safety and protection of the environment
Typical Applications Include:
Oil Refineries
FPSO (Floating Production Storage& Offtake) Facilities
Oil Rigs
Tanker Offloading (Road and Rail)
Heavy Duty Chemical Applications
Hot Oil Circulation
Petrochemical processing plants
Material:
Carbonsteel; chromed steel; austeniticstainlesssteel; duplexsteel; Titanium and Titanium Alloys; Hastelloy C-276 and other special materials; It depends the customer's request.

Containment shell·         

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 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.
