API685 Bb4 Multistage Magnetic Pump

Product introductionAPI685 Bb4 Multistage Magnetic PumpMultistage, single suction, between-bearings.*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 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 requestPARTS NAMES-6A-8D-1TITANIUMHAST C276CasingCast steel316 AUSDUPLEXTiHAST CImpeller12%CR316 AUSDUPLEXTiHAST CContainment shellHastelloy C276Hastelloy C276Hastelloy C276Hastelloy C276Hastelloy C276Inner magnet rotor304/SM2C017316/316/ SM2C017Ti /SM2C017HAST C/ SM2C017Pump shaft12%CR316 AUS2205TiHAST CSlide bearing304/SSIC316/SSIC316/SSICTi/SSICHAST C/SSICContainment 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.Company profileEstablished in 2002 ,DalianKehuan PumpCo.,Ltd. is leading manufacturer on pump design and manufacture that meet the most exacting quality requirements.DalianKehuanPumpCo.,Ltd has two plants,one is manufacturing as sembly and testplants, anotheri spacking and delivery workshop.Plants coversan area of 20,000 squaremeters ,and the workshop covers an area of 12000 squaremeters, office building covers an area of 3000 squaremeters.Technical capability-Team leaders have more than 30 years of  rich experience in researching ,designing and manufacturing pumps.-we have an excellent technical team to design and develop new products. So we can provide a strong technical support for you.-The products are designed with the help of CAD systerm,solideworks,CFD analsys.-Our major products are in the compliance with the standards of API610,API685, ANSI,ISO,DIN,HI,etc.-To fulfill the requirement of our customers we customize our pumps by adopting new design.-Perfect and mature technologic process.-We have a advanced computer assisted testing system to hold the product quality.Manufacturing capabilitySystematic solutions for pump manufacturing process: pattern marking, component machining,Pump assembling, performance testing,painting and packing.Workshop area 12000m2,Max.lifting weight 10 tons,Max.lifting height10m.Production equipment and capability Through with relocation and modification , our company invested in an umber of high- tech and high performance  production  equipment,with nearly 60 various machines including high precision CNC machines and numerical control machines,the facilities are able to meet all machining requirement of partsand components for small & large pumps.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 pumpsNon-metal
