High Pressure Shaft Seal in OMP X and OMR X motors OMP X and OMR X motors feature op ons with High Pressure Sha Seal (HPS), with check valves and with or without drain connec on. OMP X/ OMR X with drain connection The sha seal pressure equals the pressure in the drain line. OMP X/OMR X without drain connection The sha seal pressure never exceeds the pressure in the return line.

Figure 8 OMP X and OMR X shaft loads The curve shows the rela on between PR and n: • when l = 30 mm [1.18 in] for motors with A2 (European version) • when l = 24 mm [0.94 in] for motors with square moun ng flange and A2 (US version) For applica ons with special performance requirements, we recommend OMP X and OMR X with the output sha running in needle bearings. Figure 9 OMP X N shaft loads The output sha on OMP X N can be offered in needle bearings. These bearings and the recessed moun ng flange allow a higher permissible radial load in comparison to OMP X motors. The permissible radial load on...
