Unique Double 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.   Selection     First selection is based on nominal torque , Max bore , Max speed , end fitment. Next for Diesel / Compressor drives in particular - TV analysis is performed to check that vibratory torques are within acceptable limits in operating speed range. If necessary several sizes are tested - to obtain best match Unique" would be glad to perform TV analysis on request. For this normally we would require Mass elastic data , Torque - Crank angle data ( for compressors)     Note:   Many alternative custom made designs can be offered to suit specific requirements. Torsional stiffness may vary + - 20 % of catalogue figures.    Key Features:   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

Advance analysis and manufacturing process have produced increased rating without reducing safety factors. The use of Torsional VibrationAnalysis package has allowed for a more precise calculation on the drive system stresses. Flexible couplings are a vital part of mechanical power transmission system. Unfortunately some consider it a hardware only. It hardly costs 1% of the total system cost. And yet it can cause severe financial losses when improperly designed selected or operated.
