10K Orbital Hydraulic Motor
Our 10K-class high-torque orbital hydraulic motor is engineered for heavy-duty mobile and industrial applications. Available in 345–940 cc/rev displacements, it provides up to 2,700 Nm of continuous torque and 170 L/min of continuous flow. The motor combines high power density, low pressure drop and excellent side-load capacity with a robust bearing design for reliable operation in demanding working conditions. It is suitable for boring equipment, port machinery, sawmill equipment, metal forming machinery and other high-torque applications.
- Product Introduction
The 10,000 Series is the larger disc valve motor. In continuous duty, this motor delivers up to 170 L/min (45 GPM) flow and 2700 Nm (23,910 in-lbs) of torque. Powerful yet highly efficient, this motor also provides exceptional side-load capability, making it ideal for demanding mobile and industrial applications.

Operating & Maintenance Guidelines
Break-in recommendation: Before applying full load, run the motor in low-speed, high-torque mode at approximately 30% of continuous pressure and 50% of continuous flow for 30 minutes in each direction.
Maximum inlet pressure: 275 bar (4000 PSI). Do not exceed the delta pressure rating.
Maximum return pressure: 275 bar (4000 PSI) with case drain line installed. Do not exceed the delta pressure rating.
Maximum case pressure: 20 bar (300 PSI).
Recommended hydraulic fluid: Premium quality anti-wear hydraulic oil with viscosity not less than 13 cSt (70 SUS) at operating temperature.
Operating temperature range: -34°C to 82°C (-30°F to 180°F).
Recommended filtration: Per ISO Cleanliness Code 4406: 20/18/13.
Thermal shock warning: Do not operate the motor with fluid that is 70°F or more above the motor temperature.
Minimum delta pressure: A minimum of 50 PSID must be maintained between inlet and outlet ports at all times (except when switching direction of rotation).
