The OMT ND86P2 pump half coupling is designed for group 2 gear pumps and is used in assembling pump-motor units (pump + electric motor). It mounts on a pump shaft with a 17.2 mm diameter and two keyways — 4 mm and 3.2 mm. Used together with the R-82 elastic spider and ND86B motor half coupling, it ensures precise shaft alignment and reliable torque transmission. OMT half couplings are engineered to handle high torque and can compensate for angular, radial, and axial misalignments. Compatible with standard-flange electric motors up to 315 kW and group 2 pumps.
