BMR Series LSHT Hydraulic Motors for Mining Machinery & Drilling Rigs

Product Overview: The BMR Series orbital hydraulic motor is a power unit specifically engineered for heavy-duty industrial environments, widely utilized in mining machinery, geological drilling rigs, and construction vehicles. This category features the complete displacement spectrum: BMR-50, BMR-80, BMR-100, BMR-160, BMR-200, BMR-250, BMR-315, BMR-395, BMR-400, and BMR-500. Utilizing advanced Gerolor technology, the BMR series incorporates rollers in the stator set to significantly reduce friction, providing higher starting torque and extended service life. It is the premier choice for drill head rotation, material conveyors, mining winches, and mini-sweeper drives.

Key Technical Advantages:

• Reinforced Gerolor Design: Internal rollers minimize friction losses, ensuring smooth torque delivery even at ultra-low speeds—effectively preventing stalling during rigorous drilling operations.

• High-Pressure Shaft Seal: Equipped with premium high-pressure resistant seals, allowing the motor to handle significant back pressure in series circuits, greatly reducing the risk of leakage.

• Compact & Durable Construction: The housing is crafted from high-strength ductile iron to withstand impacts and vibrations in mines and drill sites, with a compact frame for easy installation in tight spaces.

• Optimized Spool Valve Technology: Automatically compensates for pressure loss, ensuring superior volumetric efficiency across varying pressure fluctuations.
