Features Single seal Balanced Independent of direction of rotation Stationary springs Dual seals in tandem as well as back-to-back arrangements (also in combination with H10 seal) 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 reversals Operation in vacuum without additional seat locking possible No damage of the shaft by a dynamically loaded O-Ring Small installation sizes Best suitable for conversions, no adaptations of the pump Insensitive to solid containing and abrasive media Advantages of a balanced seal even with plain shafts Insensitive to shaft movements because of the stationary design Recommended applications Water and waste water technology Refining technology Dirty, abrasive and solid containing media Fugitive hydrocarbons (no API seal!) Sticky and stringy media Chemical standard pumps Sewage pumps Operating range Shaft diameter: d = 18 ... 100 mm (0.71" … 3.94") 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) Axial movement: ±1.0 mm * Additional seat locking is not needed in vacuum operation. For operation under vacuum it is necessary to arrange for quenching on the atmosphere side.
