IMB/IMCIMB / IMC / INM / IPM Series Radial Piston Hydraulic Motors
Hydraulic Motors INI IMB/IMC

INI low-speed high-torque radial piston motors. INM (INM05–INM7, Italian technology from a former JV): displacement 59–4,298 cc/rev, rated pressure 25 MPa, peak up to 45 MPa, torque 235–17,100 N·m, speed up to 1,000 rpm — the basis of INI winches and transmissions. IMB with hydrostatically balanced con-rods: 988–6,807 cc/rev, 23/29 MPa, up to 22,404 N·m, interchangeable with Staffa HMB. IMC two-speed motors switch displacement while running (IMC100…IMC325). IPM: 56–22,857 cc/rev, 16–20 MPa, up to 58,470 N·m; replace Intermot, Calzoni, Staffa and SAI motors of the same displacement.
