General information
F11 is bent axis, xed 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 ange and shaft end.
- F11-6, -10, -12 and -14 with ISO ange
and shaft
- F11-6, -10. -12, -14 and -19 with SAE
ange and shaft
Thanks to the unique spherical piston de-
sign, 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 cylinder
barrel allows for a very compact, lightweight
motor/pump.
The laminated piston ring offers important
advantages such as 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 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
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 straightforward 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.
Note! F11-150 and -250 have been updated to F12-150 and -250. They can be found in
the service manual for F12. We also refer to after sales information, SI 09/01 and SI 09/04.

Operating temperature
The following temperatures should not be exceeded
(Type N shaft seals): Drain uid: 90 °C.
FPM shaft seals (type V) can be used to 115 °C
drain uid temperature.
Note: The temperature should be measured at the
utilized drain port.
Continuous operation may require case ushing in
order to meet the viscosity and temperature limitations.

Design
Series F11 pumps/motors consist of a rotating group contained in a split housing. Spherical
pistons (1) with laminated piston rings (2) operate at a 40° angle relative to the shaft (3). As
the shaft turns, the pistons are driven in a reciprocating movement in the cylinder barrel (4).
When the unit is used as a pump, the oil passes from the inlet port to the cylinder barrel and is
then forced to the outlet port through the pumping action of the pistons.
A barrel retaining ring maintains the barrel against the valve plate (5). A ring gear (6) on the
shaft meshes with the corresponding teeth of the cylinder barrel (4) so that the cylinder barrel
always rotates at the same speed as the shaft (3). The shaft is supported by two heavy duty
tapered roller bearings (7).

Operational Check
The general condition of the unit can be established by checking the drain ow. Remove the
drain line and keep the drain port above a suitable container. Run the unit at normal speed
and pressurize the system to 150 - 200 bar (2000-3000 psi).
Measure the drain ow for one minute; if it exceeds the maximum gures shown below, the
unit is worn or damaged internally and should be replaced or repaired. Also, check for leakage at the shaft seal and between the bearing and barrel housings.
