Torsiflex-I Disc Couplings
Torsiflex-i disc couplings are specifically designed for process pump and general industrial applications. Torsiflex is an all-metal disc coupling requiring no lubrication which incorporates a plug-in feature to allow installation and removal without disturbing the pump alignment.
Advantages- Standard coupling is fully compliant with the requirements of API 610 / ISO 14691
- Plug-in spacer design allows installation and removal without disturbing the hubs
- Inch series hub attachment screws (Metric available upon request)
- Robust disc pack design allows for greater torque load in a smaller coupling, resulting in lower weight
- Large bolts for high clamp load, increasing frictional torque load, and reduced bolt bending stress
- Max bores matched to NEMA motor shafts, resulting in up to 60% weight savings per application
- Smaller diameter and lower weight per HP provide better inherent balance
- ATEX compliance is standard — Exll 2GDc135degC(T4)
- Built-in Anti-Flail Feature
- Zinc Phosphate coating standard
- Large hubs available on first two sizes
- Compliance with API 671 / ISO 10441 is available
California Proposition 65 Warning: This product contains chemicals known to the State of California to cause cancer and/or birth defects or other reproductive harm.
Features
- Torsiflex-i couplings consist of 2 hubs and a factory assembled transmission unit.
- Installation involves fitting the hubs to the machinery shaft ends, introducing the transmission unit, then securing with the attachment screws
- MAXIMUM SPEEDS shown are for standard materials. When higher speeds are required please consult Ameridrives Couplings
- PEAK TORQUE of 1.75 and MOMENTARY TORQUE of 2.7 times the stated ratings are accepted
- SPARK FREE overload protection is provided as a standard feature on all Torsiflex-i couplings, making them suitable for GAS ZONE environments
- STANDARD COUPLINGS are designed for general purpose applications and are suitable for the majority of process pump, fan, and compressors applications
- SPECIAL COUPLING versions available include:
- Torque overload protection
- Limited end float
- Electrical Insulation
- Bolted adapters suitable for high cyclic torques
- Hubs: Carbon Steel
- Spacers: Carbon Steel
- Adapters: Carbon Steel
- Discs: Stainless Steel (301)
- Bolts: Alloy Steel
- Nuts: Alloy steel
- Overload Collars: High strength "non-sparking" material
- ATEX Approval Certificate No. SIRA 03ATEX205
