SS-HRN: Burgmann HRN mechanical seal replacement
Features:
Equivalent to Burgmann HRN
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)

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)

Materials:
Seal face: Carbon graphite resin impregnated (B), 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 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
