Low Speed High Torque Nhm (S) 11 External Five Star Radial Piston Hydraulic Motor

The NHM(S)11 features a reinforced external five-star stator and dual-row roller bearing crankshaft, delivering up to 12,000 Nm torque at 1 RPM with 35 MPa peak pressure, making it ideal for large-displacement applications like ship anchor winches and 4000-ton injection molding machines where standard motors fail.

Yes, the NHM(S)11s optimized valve plate timing and hardened piston shoes absorb shock loads without torque ripple, ensuring smooth low speed high torque operation in marine deck cranes, steel mill rollers, and mining excavators even during sudden load reversals or stall conditions.

Absolutely. Reversible rotation is factory-standard on all NHM(S)11 units, enabling seamless forward/backward operation in anchor winches, mooring systems, and heavy-lift cranes without additional valves, reducing system complexity and maintenance costs in marine hydraulic systems.

The NHM(S)11 series covers displacements from 8,000cc to 13,000cc per revolution, specifically engineered for applications requiring massive torque at ultra-low speeds without gearboxes, such as tunnel boring machines, rubber mixers, and offshore platform positioning systems.

The NHM(S)11 is manufactured to identical Italian Intermot technical standards with fully interchangeable mounting flanges, shaft dimensions, and port configurations, offering a cost-effective, high-pressure drop-in replacement for Staffa HMC6 and Italgroup NHM11 external five star motors with 30% faster lead times and full warranty support.
