Short description Axial piston motor FMF --- The Liebherr axial piston motors in the FMF series are designed as swashplates for open and closed circuits. The constant-displacement plug-in motors are available in finely graded nominal sizes ranging from 1.53 to 15.26 inch3 (25 to 250 cm³). The nominal pressure is 5,076 or 6,092 psi (350 or 420 bar) and the maximum pressure is 5,511 or 6,527 psi (380 or 450 bar), depending on the nominal size. Special features of the FMF: Designed as a plug-in motor. The valves can be integrated into the connecting plate. Speed sensor or preparation for speed sensor available on request.
