Enactus-eCartex Dual Seals Burgmann ECartex Dual Seals Replacement
FeaturesDual sealCartridgeBalancedIndependent of direction of rotationDouble pressure balancedIntegrated pumping deviceVariants available: for eccentric screw pumps (-Vario) and gas-lubricated version (-GSDN)AdvantagesThe series has sliding surfaces that are equipped with EagleBurgmann DiamondFace technology as standardUp to 80 % less energy consumption and minimized heat generation of seal due to friction-reducing DiamondFace layerUp to 100 % extended operating period,Website:, prolongation of MTBF and MTBR intervalsSignificantly improved dry-run capability for inadequately lubricated sealing surfaces, thus vastly improved process safetyUniversally applicable, even with high solids content in the mediumOperating rangeShaft diameter:d1 = 25 ... 100 mm (1.000" ... 4.000"Other sizes on requestTemperature:t= -40 °C ... 220 °C (-40 °F ... 428 °F)(Check O-Ring resistance)Sliding face material combination BQ1Pressure: p1 = 25 bar (363 PSI)Sliding velocity: vg = 16 m/s (52 ft/s)Sliding face material combination Q1Q1 or U2Q1Pressure: p1 = 20 bar (290 PSI)Sliding velocity: vg = 10 m/s (33 ft/s)Barrier fluid circulation system:p3max = 25 bar (363 PSI)Δp (p3 - p1)ideal= 2 ... 3 bar (29 ... 44 PSI),7 bar (102 PSI) for barrier media with poor lubricating properties)Pump startup:Δp (p3 - p1)max = 25 bar (363 PSI) allowedRecommended supply medium: max. ISO VG 5Axial movement: ±1.0 mm, d1 from 75 mm ±1.5 mmMaterialsSeal face product side: Silicon carbide DiamondFace® (Q15)Seat product side: Silicon carbide DiamondFace® (Q15)Seal face atmospheric side: Carbon graphite resin impregnated (B)Seat atmospheric side: Silicon carbide (Q1)Secondary seals: FKM (V), EPDM (E), FFKM (K), Perfluorcarbon rubber/PTFE (U1)Springs: Hastelloy® C-4 (M)Metal parts: CrNiMo steel (G), CrNiMo cast steel (G)Recommended applicationsPetrochemical industryChemical industryPharmaceutical industryPower plant technologyPulp and paper industryMining industryFood and beverage industrySugar industryUniversally applicableCentrifugal pumpsEccentric screw pumpsServiceProvide special designAccording to the requirements and conditions for the custom processing
