General information
F12 is bent axis, fixed displacement
heavy-duty motor/pump series. They
can be used in numerous applications
in both open and closed loop circuits.
Series F12 conforms to current ISO
and SAE mounting flange and shaft
end configurations.
Frame sizes: F12-152, -162, -182
Thanks to the unique spherical piston
design, 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 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 F12 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 F12 very tolerant to high ’G’
forces and torsional vibrations.
Heavy duty roller bearings permit sub-
stantial external axial and radial shaft
loads.
The F12’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.
