Series F11
General information
F11 is bent axis, fixed displacement
heavyduty motor/pump seris. They can
be used in numerous applications in
both open and closed loop circuits.
Series F11 are available in ISO, CETOP,
SAW and SAE versions.
The F11 series are available in sizes 5,
6, 10, 12, 14 and 19 cc.
Thanks to the unique spherical piston
design, F11 motors can be used at
unusually high shaft speeds. Operating
pressures to 420 bar provides for the
high output power capability.
The 40° angle between shaft and cylin-
der barrel allows for a very compact,
lightweight motor/pump.
The laminated piston ring oers im-
portant advantages such as low inter-
nal leakage and thermal shock resis-
tance.
The pump version has highly engine-
ered valve plates for increased selfpri-
ming speed and low noise, available
with left and right hand rotation.
The F11 motors produce very high tor-
que at start-up as well as at low speeds.
Our unique timing gear design synch-
ronizes shaft and cylinder barrel, ma-
king the F11 very tolerant to high ’G’
forces and torsional vibrations. Heavy
duty roller bearings permit substantial
external axial and radial shaft loads.
The F11’s have a simple and straight-
forward design with very few moving
parts, making them very reliable mo-
tors/pumps.
The unique piston locking, timing gear
and bearing set-up as well as the limi-
ted number of parts add up to a very
robust design with long service life
and, above all, proven reliability.
