Product Description
OMH series orbital motors are medium-duty low-speed high-torque hydraulic motors adopting integrated geroler roller gear set and shaft distribution valve design. Displacement covers 200–500 cc/rev, max continuous working pressure up to 175 bar. With high radial & axial bearing capacity, compact ductile iron housing and high back-pressure resistant shaft seal, they support series & parallel circuit connection, perfectly interchangeable with Danfoss original OMH motors for agricultural, light construction and sanitation equipment.
Integrated roller geroler structure, low startup pressure, smooth full-speed rotation without crawling, stable torque output
Reinforced double bearing design, strong radial & axial load capacity, suitable for direct wheel drive and heavy rotary loads
High-pressure resistant shaft seal, withstand high return pressure without independent drain line, simplify hydraulic piping layout
Compact lightweight casting housing, 4-bolt magneto mounting flange, flexible side port layout for narrow installation space
Hardened rotor & stator pair, low internal leakage, high mechanical efficiency, long service life under continuous medium-load operation
Full interchangeable with original Danfoss OMH series, multiple shaft & displacement options, support OEM customized logo & packaging
Perfect Interchangeability
Identical mounting dimensions, port positions and performance parameters with Danfoss OMT/OMV series, direct plug-and-play replacement.

Factory&FAQ
OMH Series Orbital Motorsare typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
1. What is the OMH Series Orbital Motors ?
Integrated roller geroler and shaft distribution valve design delivers low startup pressure and stable torque without crawling.
High back-pressure resistant shaft seal allows series & parallel connection, simplifying piping layout.
Compact ductile iron housing with standard 4-bolt magneto flange fits narrow installation space.
Double reinforced bearings support heavy radial and axial loads for direct wheel and rotary drive.
Fully interchangeable with Danfoss OMH, multiple displacements and shaft options available, with 12-month warranty.
3. What is the working pressure range of OMH Series Orbital Motors ?
Max continuous working pressure: 175 bar (2538 PSI)
Max intermittent peak pressure: 210 bar (3045 PSI)
Max allowable back pressure: 100 bar
4. Can OMH Series Orbital Motors replace other brands?
It is fully interchangeable with original Danfoss OMH series, with identical mounting flange, port position, spline shaft and performance parameters, plug-and-play without modifying equipment frames or pipelines.
It can serve as equivalent replacement for Eaton, M+S and other geroler-type medium-duty orbital motors with matching displacement and mounting size.
We supply multiple shaft, port and displacement options to match different brand original motors, and support customized solutions for special replacement demands.
6. What is the typical speed range of OMH Series Orbital Motors ?
Max speed of OMH200 (smallest displacement): 366 rpm
Max speed of OMH500 (largest displacement): 152 rpm
For stable high torque output, large displacement models usually run below 200 rpm.
7. Do you provide OEM or customized services?
OEM service: Custom brand logo printed on motor housing and export cartons.
Custom options: Special spline shafts, modified port positions, customized mounting flanges, and exclusive packaging.
MOQ: 1 unit for standard customized requests; bulk order discounts for large OEM orders.
We can adjust technical parameters slightly to match your special equipment requirements.

The Green hydraulic pump manufacturing facility is a specialized industrial plant that focuses on producing hydraulic pumps and related components. These factories are equipped with advanced machinery and technology to fabricate high-quality pumps designed for a wide range of applications, from heavy equipment and machinery to automotive and industrial systems. 
The production process typically involves precision engineering, where raw materials like metals and alloys are processed into pump components such as gears, pistons, cylinders, and seals. These parts are then assembled into fully functional hydraulic pumps, which are tested for performance and quality control to ensure reliability, efficiency, and durability under various working conditions.
