Staffa HMC Series Two-Speed High Torque Radial Piston Motors

Product Overview: The Staffa HMC Series is a world-class drive solution for heavy-duty industrial and marine applications. As an advanced dual-displacement radial piston motor, it allows for seamless shifting between high and low displacement via pilot control without interrupting operation. This featured selection covers the core HMC lineup: HMC080, HMC100, HMC125, HMC200, HMC270, and HMC325. Specifically engineered to balance “heavy-load hoisting” with “light-load high-speed recovery,” these motors deliver unparalleled stability at continuous pressures up to 250 Bar with over 95% starting efficiency.

Key Technical Advantages:

• Smooth Shifting Under Load: The HMC series supports dynamic displacement changes while running, allowing operators to optimize torque and speed instantly, significantly reducing cycle times.

• Exceptional Starting & Mechanical Efficiency: Utilizing hydrostatically balanced connecting rod technology, friction loss is minimized. It delivers constant, smooth output even at ultra-low speeds, effectively preventing load slippage.

• High-Pressure & Robust Construction: Rugged housing and reinforced bearing designs allow the motor to handle extreme radial and axial loads, making it ideal for the harshest offshore and mining environments.

• Superior Low-Speed Performance: The radial piston arrangement eliminates low-speed “cogging,” ensuring high-precision operation at speeds below 1 RPM.

• Target Applications: Marine deck winches, constant tension systems, rotary drilling rigs, injection molding screw drives, and heavy-duty conveyors.
