Liebherr FMF Fixed-Displacement Plug-In Axial Piston Motor for hydraulic equipment

liebherr fmf — Original INTEREQ-designed plug-in axial piston motor, more front-facing view

Confirm that the Liebherr FMF hydraulic motor matches the machine; use the complete type code to verify compatibility. Liebherr FMF Fixed-Displacement Plug-In Axial Piston Motor is part of Liebherr’s axial-piston hydraulic components portfolio. The FMF family is intended for hydraulic equipment where circuit type, nominal size and operating characteristics match the machine design. Variants within one family can differ in displacement, controls and mechanical interfaces.

The family name and nominal size identify only part of the configuration. A complete type code, nameplate image and machine information are needed to assess replacement suitability. This listing is a family-level reference; it does not mean that every variant is directly interchangeable.

Applications

Agriculture and forestry, construction, maritime applications, mining and special vehicles.

In a complete hydraulic system, the pump or motor must match the drive, controls, charge or auxiliary circuit, filtration, cooling and case-drain arrangement as applicable. Check the machine documentation and operating duty before specifying a component.

Key features and compatibility

Sizes have different pressure and speed limits. Match nominal size, rating, plug-in interface, shaft, port pattern, rotation and circuit type to the original motor.

Compare the original unit’s control response, drive interface, pressure and speed range, port arrangement, rotation and fluid requirements. Confirm limits for the exact version rather than relying on family-level values alone.

Model identification and replacement selection

Send the full type code, nameplate and interface measurements. Confirm speed, torque, fluid, case drain and application requirements against the exact manufacturer data sheet.

For a quotation, provide the complete Liebherr type code, machine make and model, a legible nameplate photo, and photographs or measurements of the shaft, mounting face and hydraulic ports. If the nameplate is incomplete, those details help identify remaining configuration differences.
