Staffa HMB & HMC Motor | HMB030, HMB080, HMB200, HMC200 | Radial Piston LSHT

Staffa HMB & HMC Series LSHT Radial Piston Motors

Product Overview: The Staffa HMB and HMC Series represent the pinnacle of radial piston technology for industrial and marine applications. Renowned for their exceptional power density and smooth operation at ultra-low speeds, these motors are the industry benchmark for durability. This selection covers the entire spectrum from compact to heavy-duty frames: the Fixed Displacement HMB Series (HMB030, HMB080, HMB100, HMB200, HMB325, HMB400) and the Dual Displacement HMC Series (HMC100, HMC200). Featuring a unique hydrostatically balanced connecting rod design, Staffa motors minimize friction and wear, providing consistent power delivery even at continuous pressures exceeding 250 Bar.

Key Technical Advantages:

• Superior Starting Efficiency: The precision-engineered rotating group ensures a starting torque of over 95% of nominal torque, ideal for winch hoisting and heavy-load start-stop cycles.

• HMC Dynamic Speed Control: The HMC series allows for seamless displacement shifting under load, providing a perfect balance between high-torque/low-speed and low-torque/high-speed modes.

• Extreme Reliability & Service Life: A rugged housing combined with high-capacity bearings allows for substantial axial and radial load handling, significantly extending operational life in harsh environments.

• Smooth Low-Speed Performance: The radial piston arrangement guarantees pulse-free operation at speeds below 1 RPM, ensuring precise control for critical tasks.

• Target Applications: Marine deck machinery (winches, windlasses), injection molding screw drives, rotary drilling rigs, Tunnel Boring Machines (TBM), and heavy-duty steel mill drives.
