F11 and F12 are bent axis, fixed displacement heavy-duty motor/pump series. They can be used in numerous applications in both open and closed loop circuits.
• Series F11 is available in the following frame sizes and versions:
- F11-5, -6, -10, -12, -14 and -19 with CETOP mounting flange and shaft end
- F11-10, -12 and -14 with ISO flange and shaft
- F11-10, -12, -14 and -19 with SAE flange and shaft
• Series F12 conforms to current ISO and SAE mounting flange and shaft end configurations. A very compact cartridge version is also available.
• Thanks to the unique spherical piston design, F11/F12 motors can be used at unusually high shaft speeds. Operating pressures to 480 bar provides for the high output power capability.
• The 40° angle between shaft and cylinder barrel allows for a very compact, lightweight motor/pump.
• The laminated piston ring offers important advantages such as 18 low internal leakage and thermal shock resistance.
• The pump version has highly engineered valve plates for increased selfpriming speed and low noise, available with left and right hand rotation.
• The F11/F12 motors produce very high torque at start-up as well as at low speeds.
• Our unique timing gear design synchronizes shaft and cylinder barrel, making the F11/F12 very tolerant to high 'G' forces and torsional vibrations.
• Heavy duty roller bearings permit substantial external axial and radial shaft loads.
• The F11's and F12's have a simple and straight-forward design with very few moving parts, making them very reliable motors/ pumps.
• The unique piston locking, timing gear and bearing set-up as well as the limited number of parts add up to a very robust design with long service life and, above all, proven reliability.
