KTR N-EUPEX A 65 Pin Coupling — Robust Flexible Coupling for Heavy Duty Applications

KTR N-EUPEX A 65 Pin Coupling — Replaceable Flex Elements for Heavy Duty Saudi Industrial Drives

The KTR N-EUPEX A 65 is a pin-type flexible coupling where torque is transmitted through flexible (rubber) pin bushings into steel flanges. This design provides vibration damping and misalignment compensation while allowing quick replacement of rubber elements without removing the coupled equipment.

Saudi water injection operators use N-EUPEX A 65 on high-pressure water pump drives where the coupling must handle torsional vibration and radial misalignment from thermal growth in outdoor installations. Replaceable rubber pin bushings can be changed in under 30 minutes.
