Enactus-BT-AR Burgmann BT-AR Replacement
FeaturesRubber bellows mechanical sealUnbalancedSingle springIndependent of direction of rotationShort axial installation lengthAdvantagesMechanical seal for large-series cold water pumps,Website:, produced in millions of units per year. The BT-AR owes its success to the wide range of application, the short axial length (this allows for more economic pump construction and saves material), and the best quality/price ratio. The elasticity of the bellows design enables a more robust operation.The BT-AR can also be used as a multiple seal in tandem or back-to-back arrangement when the product media cannot ensure lubrication, or when sealing media with a higher solids content. Installation proposals can be provided upon request.Operating rangeShaft diameter: d1 = 6 ? 70 mm (0.24" ? 2.76")Pressure: p1* = 6 bar (87 PSI),vacuum ? 0.5 bar (7.45 PSI) up to 1 bar (14.5 PSI) with seat lockingTemperature:t* = -20 ?C ? +120 ?C (-4 ?F ? +248 ?F)Sliding velocity: vg = 10 m/s (33 ft/s)* Dependent on medium, size and materialMaterialsSeal face:Carbon graphite antimony impregnated (A), Carbon graphite resin impregnated (B), Carbon graphite, full carbon (B3), Silicon carbide (Q1, Q6), Tungsten carbide (U), PTFE glass fiber reinforced (Y)Seat:Steatite (X), Aluminium oxide (V, V1), Silicon carbide (Q1, Q6, Q7), Tungsten carbide (U), Cr steel (E), CrNi steel (F), CrNiMo steel (G)Elastomers:NBR (P), EPDM (E), FKM (V), HNBR (X4)Metal parts:CrNi steel 1.4301 (F), CrNiMo steel 1.4401 (G), CrNi steel 1.4057 (F1)Recommended applicationsWater and waste water technologyPool and spa applicationsHousehold appliancesDomestic and garden pumpsWhirlpool and swimming pool pumpsDishwasher pumpsSubmersible motors / pumpsWater pumps / waste water pumpsServiceProvide special designAccording to the requirements and conditions for the custom processing
