| | Pin Bush Coupling  Item Code: Pin-Bush-Coupling | - Unique PB Pin Bush Couplings are used in General Engineering applications for reliable power transmission under normal shaft misalignment.
- Couplings dampen shocks and vibrations
- Progressively increasing stiffness characteristics of special shaped buffers ensure control of vibration amplitude for protection of equipment.
- Couplings can take considerable overloads.
- Standard range has hubs of Cast Iron
- For special applications couplings with forged steel hubs available. Brake Drum Coupling
- Also available couplings with Brake Drum
- Couplings with spacer.
- Special barrel shaped buffers provide superior torsional resilience. Deformation of barrelled buffer with increasing loads
| Tyre Couplings Item Code: TC-PH-PX-U | - 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 characteristics ensure vibration amplitude are limited at resonance. Design Series - Series 1000 , Series 1100 are for Direct Flywheel mounting.Series 1750 are for shaft to shaft connection.Series IP are suitable for diesel drives in association with cardan shaft - highly popular for Diesel driven vertical Turbine Fire Pumps | | | | Flexible Laminated Disc Couplings Item Code: Metaflex | Metaflex All Metal Dry Flexible Laminated Disc( Membrane/ Diaphragm ) Couplings - Couplings specially designed for Petrochemical Industry meeting API 610 requirements. Can be supplied to meet API 671 requirements.
- These are High Performance Couplings of all metal Construction for high speed as well as slow speed applications.
- Couplings require no lubrication. Require very little maintenance.
- Highly popular for Turbine/Pump/Fan/Compressor/Paper Mill/Sugar Mill Drives Supplied for Powers upto 12000 KW for both high speed & slow speed.
- Metaflex Floating shafts are available in single span - multispan.
- Lengths upto 20 metres in service for vertical Pumps. Ideally suitable for Vertical Pump Drives
- Also available with adjustable lengths - with Shrink Disc / Spline arrangement
- Torsional Vibration Analysis on request
