Containment shellThe 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 bearingThe 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 bearingThe ball bearing is NSK or SKF bearings.Lubrication: Grease or Oil, It depends the customer's request.Magnetic materialThe 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.
Application: Liquid chlorine transferring and packaging from sealed vessel .Key features :

1. 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.
2. The pump is double casing multi-stage section ring type with less sealing points.
3. 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.
4. The modular theory design makes compact structure, parts generalization and easy maintenance.
5. The pump standard confirms to GB3215 and API685.
6. 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.
7. 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 chlorine is still completely sealed without any leakage.
8. The magnet material is made of special rare earth alloy with demagnetizing temperature up to 450ºC through special technology. So the pumps are guaranteed 15 years of operation life;
9. The slide bearing material is high purity of 99% silicon carbide, and all the friction couples of bearing are high quality silicon carbide. Its high strength, elasticity, tenacity and wearing resistance is no doubt most suitable for liquid chlorine application.
10. The axial thrust balancing is important for liquid chlorine 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.
11. The rolling bearing is used SKF or NSK of grease lubrication maintenance-free type.

Company profile Dalian Kehuan Pump was established in 2002 ,Registered capital:50 million RMB. The factory covers an area of 20,000 square meters. and the workshop area is more than 10,000 square meters.
There are 150 employees, and many of the main management and technical personnel are from well-known pump companies. Sales in the last three years have remained within the range of 100 to 120 million.
Kehuan Pumps specializes in the research and development, design, manufacturing and continuous improvement of high level magnetic pumps. The original intention of the general manager is to believe that technology and environmental protection are the major trends and future themes. We advocate: Enjoy technology and protect the environment. This is also the origin of the company name. The reasons why we did not choose a canned motor pump and chose a magnetic pump mainly consider several aspects:
1. The magnetic pump has a flexible structure and has good interchangeability with ordinary centrifugal pumps.
2. Convenient inspection and maintenance, low maintenance cost, and energy saving than canned motor pump.
3. At present, domestic magnetic pumps cannot be used as large pumps. Foreign magnetic pumps account for much higher proportions than canned motor pumps, so we need to reinforce them.

Metallic magnetic drive seal-less pumps	Non-metallic magnetic drive seal-less pumps	Canned motor seal-less pumps	Double mechanical seal pumps
No leakage High design pressure No seal Low maintenance cost, easily maintenance. SSIC slide bearing, Long service life. Large internal gap, resistant to particles	No leakage Low design pressure No seal Low maintenance cost, easily maintenance. SIC slide bearing, Lower service life. Small internal gap, not resistant to particles	No leakage High design pressure No seal Higher maintenance cost, Always need to return to factory for maintenance, long cycle. SSIC slide bearing Long service life. Small internal gap, not resistant to particles	leakage High design pressure Complicated double mechanical and flushing plan. Higher maintenance cost, Mechanical seal and rolling bearing, high maintenance frequency No slide bearings Long service life. Large internal gap, resistant to particles

First, there are a lot of South magnet pumps manufacture focus on PVDF magnetic pumps and low-standard metal magnetic pumps (design standards JB/T 7742 and HG/T 2730) .They are limited by their own capabilities and cannot cope with many working conditions.
Second: Some joint ventures have not fully engaged in the development of magnetic pump. For example, H company, which has been in the Chinese market for many years, mainly promotes canned motor pumps in order to cater to the preferences of the Chinese market. The magnetic pump, which should have been vigorously developed, has not been updated for decades. Their magnetic pumps can only be used in simple working conditions which is less than 132kw.
Kehuan pump must make a comprehensive breakthrough in the status quo of magnetic pumps (such as High power, High temperature, Mud, Easy vaporization, High melting point, etc.)
Design framework: We use European advanced hydraulic model;
Design standards according to American petroleum institute standard API685.
High standard material application: Permanent magnet (Sm2Co17, Temp. -196~450ºC), Sliding bearing (SSIC), Containment shell(HC-276), Rolling bearing (SKF/NSK), Coupling (Wuxi Chuang ming) /German KTR), Electric motor (Nan yang/Jiamusi).
We are well-known in domestic market because of our High quality products and reliable quality assurance system, high efficiency performance and excellent solutions.
We also have long-term and stable cooperation with foreign customers. Like European, Russia, Chile, India and so on.*If you have any questions about our products, I hope you can contact me at your convenience.Thank you for your concern.
