OMP X & OMR X
The Danfoss OMP X and OMR X are high-end, fixed-displacement, Low-Speed High-Torque (LSHT) orbital hydraulic motors designed as a premium upgrade to the legacy OMP and OMR series. Built on a redesigned modular platform, these “X-Series” motors deliver up to 15% higher torque, enhanced radial load capacities, and superior shaft-seal pressure ratings reaching up to 225 bar
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
The Danfoss OMP X and OMR X are high-performance, Low-Speed High-Torque (LSHT) orbital hydraulic motors built on an upgraded modular platform. Representing the latest generation of the classic Danfoss O-Series, these motors function as fixed-displacement units that convert hydraulic fluid energy into smooth, rotating mechanical power. They feature an integrated High-Pressure Shaft (HPS) seal rated up to 225 bar, built-in check valves, and a design optimized for both open- and closed-loop hydraulic systems.
| Parameter / Feature | Danfoss OMP X | Danfoss OMR X | X-Series Upgrades vs. Legacy |
