THM – F11 & F12 – Bent Axis Fixed Displacement Motor/Pump

Achieve unbeatable power-to-weight ratios and exceptional thermal resistance with the THM F11 and F12 Series. Engineered as high-performance bent-axis fixed displacement units, these versatile components can be seamlessly deployed as either motors or pumps in both open and closed-loop hydraulic circuits. By utilizing an aggressive 40° angle between the shaft and cylinder barrel, the F11 and F12 series deliver a highly compact, lightweight envelope packed with relentless power. Capable of withstanding extreme 'G' forces, torsional vibrations, and continuous high pressures, these motors/pumps are the ultimate solution for demanding mobile, industrial, and heavy-duty hydrostatic drives.

Shared Key Features & Engineering Advantages:-

Compact 40° Bent-Axis Architecture: The unique 40-degree angle between the shaft and cylinder barrel creates an incredibly small envelope size, delivering an industry-leading power-to-weight ratio and allowing for installation in highly restricted spaces.
Advanced Laminated Piston Rings: Engineered to offer unbeatable volumetric efficiency while providing rugged resistance against extreme thermal shocks, ensuring reliability in rapidly changing operating temperatures.
High 'G' Force Tolerance: Features a unique timing gear design that perfectly synchronizes the shaft and cylinder barrel. This makes the entire assembly highly tolerant to extreme 'G' forces and torsional vibrations.
Application-Specific Valve Plates: * Motor Versions: Equipped with highly engineered valve plates designed specifically for high-speed rotation and low acoustic noise.
Pump Versions: Feature specialized valve plates that increase self-priming speeds, lower operational noise, and are readily available in both left and right-hand rotations.
Heavy-Duty Roller Bearings: Built with premium bearings that permit substantial external axial and radial shaft loads, eliminating the need for additional external support structures.
Simplified, Robust Design: A brilliant piston locking mechanism, perfectly timed gears, and a purposefully limited number of moving parts add up to a highly robust design with proven reliability and a long, maintenance-friendly service life.

Ideal Industry Applications:-
