BM3 & HMK Series Heavy-Duty Disc Valve Orbit Motors

Product Overview: The BM3 Series orbital hydraulic motor is a precision drive unit engineered for medium-to-heavy duty industrial and mobile applications. This category covers the complete range from the compact BM3-80 to the high-power BM3-400, including the reinforced HMK-395 model. Utilizing advanced Disc Valve architecture and a Geroler® roller set, the BM3 series ensures consistent torque delivery even at ultra-low speeds. Available in BM3S (Standard) and BM3W (Wheel Mount) configurations, these motors are the premier choice for harvester propel drives, injection molding machines, construction winches, heavy-duty conveyors, and forestry equipment.

Key Technical Advantages:

• High-Efficiency Disc Valve: The independent valve plate automatically compensates for wear-induced clearances, maintaining peak volumetric efficiency throughout the motor’s operational life.

• BM3W Wheel Mount Versatility: The specialized wheel flange allows the motor to act directly as a load-bearing axle, handling immense radial loads and simplifying chassis drive designs.

• Ultra-Smooth Low-Speed Performance: Roller stator technology minimizes internal friction, eliminating pulse sensations and providing precise Low Speed High Torque (LSHT) delivery.

• High-Pressure Seal Integrity: Equipped with industrial-grade high-pressure seals, these motors manage significant back-pressure, ensuring leak-free performance in rigorous environments.

• Technical Decoding:

  • BM3-80 to BM3-160: Optimized for rapid response and balanced torque/speed ratios.

  • BM3-200 to BM3-400: Engineered for heavy-load tasks requiring maximum traction or pushing power.

  • HMK-395: A reinforced upgrade model tailored for specific OEM requirements.
