Seal HRN Features (HBRN)
- 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)
Seal HRN Material
- 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)
Seal HRN Advantages (HBRN)
- 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
Seal HRN 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
