Magnetic Drive Centrifugal Pump

Themagnetic drive centrifugal pump hasbeengrantedaChinesepatent.ThepatentnumberisZL98242562.7. Thegreatestfigureofthepumpsis100%non-leakage.Theyaresuitablefortransmittingno-particlecontainingandtherelativedensitynomorethan1.84cleanliquid,especiallyexplosive,toxic,harmful,corrosiveandpreciousliquid.So,theycanbeappliedinproductionprocessinpetroleum,chemical,petrochemical,pharmaceutical,bioengineering,dyeing,printingandfood,etcindustries. Allinall,Non-leakagemagneticdrivepumpsareidealenvironmentalprotectingproducts. FeaturesThepumpsmanufacturedinDTEIfeaturesthemselvesasfollows,comparingthemwithsomepumpsmadeinbothcompaniesinChinaandcompaniesinforeigncountries: 1.Thestructureandperformancesofthemagnetictransmissiondeviceareataleadinglevelintheworld.Aspecialdenselypacked,gathered,pullingandpushingcouplingmagneticdrivingdeviceisadoptedinourpumps.Thepumpsfeaturesthemselvessmallvolume,greatmoment,smalleddyflow,hightransmissionefficiencyandgoodreliability(eliminatingslippossibilitybecauseofmagneticstructure)comparingwiththelikeproductsthosearemanufacturedinsomedevelopedforeigncountriesandmostlyadoptdispersed,gapkept,inter-attractingmagneticcircuitcouplingdrivingdevice.Ourproductsgetridoftheshortageoftheirproducts.Therefore,ourproductsareleadinglevelproductsallaroundtheworld. 2.Thepump’sefficiencyis10-15%higherthanthelikeproductsmanufacturedinsomeforeigncompaniesfromsomedevelopedcountriessuchasHMDcompanyinBritish,KlauscompanyinGermanyandIWKIcompanyinJapan.Itisfirstlevelproductintheworld.Besidesthemagneticdrivingdeviceadoptspatentgrantedoptimumdesign,werunacomprehensiveoptimumdesignforpump’sstructureincludingallpartswithseveralpatenttechnologiesandcombineourspecialtechnologieswithmanufacturingknow-howtodecreaseanylosethatthepump'sefficiencysoastomaketheefficiencyofthecentrifugalpumpbeequaltotheefficiencyofglandsealpump. 3.Withlownaturalattritionrate,thepumpscanbeinoperationforlongtimewithoutmaintenance.Thereisaspecialaxialforcebalancesysteminthepump.So,theaxialforceonthepump’sshaftisnearlyzeroandthereisonlyslightmechanicalfrictiononendfaceofendthrustbearingandendfaceofbushbearingduringlongperiodofthepump’soperation.Thatiswhythepumpenjoysitselflownaturalattrition,lowfailurerateandbeinginoperationforlongtimewithoutmaintenance. 4.Vibrationandnoisefromthepumparelowerthanthelikeproductsmanufacturedinforeigncountries.
