Features:Equivalent to Burgmann HRNSingle sealBalancedIndependent of direction of rotationStationary springsDual seals in tandem as well as back-to-back arrangements (also in combination with H10 seal)Operating range:Shaft diameter: d = 18 ... 100 mm (0.71& quot; … 3.94& quot;)Pressure: p1*) = 25 bar (363 PSI)Temperature: t = -40 °C ... +220 °C (-40 °F … 428 °F)Sliding velocity: vg = 20 m/s (66 ft/s)Materials: Seal face: Carbon graphite resin impregnated (B),Website:http://www.mechanicalsealsenactus.com, Silicon carbide (Q1)Seat: Silicon carbide (Q1)Secondary seals: FKM (V), NBR (P), FFKM (K), PTFE (T)Springs: Hastelloy? C-4 (M)Metal parts: CrNiMo steel (G)Advantages: Safe operation (no fractures) because of seal face locking by square pin;Spring unit averted from the product so no sticking and clogging of the springs;Suitable for pressure reversalsOperation in vacuum without additional seat locking possible;No damage of the shaft by a dynamically loaded O-Ring;Small installation sizesBest suitable for conversions, no adaptations of the pump;Insensitive to solid containing and abrasive mediaAdvantages of a balanced seal even with plain shaftsInsensitive to shaft movements because of the stationary designRecommended applications: Water and waste water technologyRefining technologyDirty, abrasive and solid containing mediaFugitive hydrocarbons (no API seal!)Sticky and stringy mediaChemical standard pumpsSewage pumpsEnactus?-HRN Dimensions(mm) d1 d3 d6 d7 d8 d10 l1k l3 l5 l6 f mx 18332733334.737.519.52.053.0420352935336.737.519.52.053.0422373137338.737.519.52.053.0424393338340.740.020.52.053.5525403440341.740.020.52.053.5528433743344.742.521.52.053.5530453945346.742.521.52.053.5532484248349.742.521.52.053.5533484248349.742.521.52.053.5535504450351.742.521.52.053.5538564956457.745.024.02.064.0640585158459.745.0242.064.0643615461462.745.024.02.064.0645635663464.745.024.02.064.0648665966467.745.0242.064.0650706270471.747.525.02.564.0653736573474.747.525.02.564.0655756775476.747.5252.
