Low Speed High Torque Nhm (S) 16 External Five Star Radial Piston Hydraulic Motor

The NHM(S)16 features a triple-row roller bearing crankshaft and reinforced external five-star stator, delivering up to 25,000 Nm torque at 0.5 RPM with 35 MPa peak pressure, making it the ultimate ultra large displacement solution for anchor winches on 300m+ vessels and steel mill continuous casters where no other radial piston hydraulic motor can operate reliably.

Absolutely. Reversible rotation is factory-standard with symmetrical porting, enabling seamless forward/backward operation in anchor/mooring winches and deck cranes without cross-line relief valves, reducing system complexity and maintenance costs in demanding marine hydraulic systems.

The NHM(S)16 series covers displacements from 16,000cc to 22,000cc per revolution, generating up to 25,000 Nm continuous torque at 25 MPa, specifically engineered for applications requiring massive direct-drive torque without gearboxes, such as tunnel boring machines, ship propulsion auxiliaries, and rubber banbury mixers.

The NHM(S)16 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 HMC8 and Italgroup NHM16 external five star motors with 40% faster lead times and comprehensive field support.

Yes, we offer nickel-plated housings and EPDM seals for the NHM(S)16, enabling reliable operation in offshore platform splash zones, desalination plants, and chemical processing equipment where standard coatings fail, maintaining high-pressure integrity in saltwater and acidic conditions.
