Enactus-eCartex ANSI Dual Seals Burgmann ECartex ANSI Dual Seals Replacement

FeaturesDual sealAvailable for standard (eCartex-ASDN) and big bore (eCartex-ABDN) seal chambersCartridgeBalancedIndependent of direction of rotationDouble pressure balancedIntegrated pumping deviceAdvantagesThe 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, 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.
