Weight: 2.1 kg. Moment of inertia: 0.002 kgm². Applications: pumps, compressors, industrial fans, mixers. Industry compliant: ATEX II 2GD c T5.
Possible Applications
This elastomeric coupling is designed for direct-drive power transmission between electric motors and driven equipment in chemical processing, petrochemical, and wastewater treatment facilities. It excels in centrifugal pump skids, rotary gas compressors, and industrial ventilation blowers operating in hazardous or potentially explosive atmospheres. The unit is particularly well suited for top-entry fluid mixers and tank agitators subject to continuous fluid turbulence and torque spikes, where torsional dampening protects motor bearings and mechanical seals from impulse damage. Furthermore, its split element configuration makes it an ideal fit for critical HVAC supply fans and manufacturing process skids where fast element replacement is necessary without unbolting or re-aligning the drive shafts.
