Torsiflex-I Disc Couplings | Ameridrives

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.

Product 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
