Possible Applications
The Rexnord Viva coupling is engineered for high-torque drive trains in heavy-duty rotating equipment such as centrifugal pumps, large-scale industrial fans, and reciprocating compressors. Its torsionally soft elastomeric element is specifically suited for processes involving frequent shock loads or misalignment, effectively isolating the motor from the driven load to prevent premature bearing failure. In mining and chemical processing plants, the split-in-half design facilitates rapid maintenance cycles, allowing technicians to replace the flex element without disturbing the alignment of the connected shafts. The inclusion of ATEX compliance makes this unit a critical component for hazardous environments where spark prevention and reliable torque transmission are essential for operational safety.
