Unique Diaphragm Type Flexible Couplings

  • Highly Flexible and resilient
  • Low Dynamic Torsional Stiffness
  • Torsional Stiffness varies with Load
  • Isolates and dampens Torsional Vibration
  • Ideally suitable for Diesel Engine Drives ,Compressors ,Rolling Mills , DG Sets Pumps
  • Available for reputed makes of Diesel Engines & compressors.
  • Custom Design for special Requirements
  • Torsional Vibration Calculation on request
  • No Lubrication . Minimum Maintenance
Unique Diaphragm Couplings use highly flexible Diaphragms. These consist of Rubber reinforced with Nylon Chords. Further at inner and outer bolting PCD Steel ring reinforcements are used. Torque ratings are determined after extensive tests and have large service factor against rupture. Rupture torque is typically 6 to 10 times rated torque.

At nominal torque torsional angle is large - typically 10 to 15 degrees. Torsional Stiffness is low. This results in low critical speeds , usually below operating speed. Further torsional stiffness varies with load. At lower loads stiffness is lower. The Feature allows operation at wide range of speeds.Favourable damping charactistics ensure vibration amplitude are limited at resonance.
