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). Series F11-5 through -78 employ five pistons, series
F11-110 and -150 seven, and series F11-250 nine pistons.
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 pum-
ping action of the pistons.
A spring device (a retaining ring, a leaf spring, or Belleville
washers) maintains the barrel against the valve plate (item 5,
F11-5 through -150) or the end cap (item 7, F11-250). A ring
gear (6) on the shaft meshes with the corresponding teeth of
the 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 (8).

Operational Check
The general condition of the unit can be established by
checking the drain flow. 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 .
Measure the drain flow for one minute; if it exceeds the
maximum figures 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.

Tools and Supplies
Metric Allen keys, retaining ring spanners, and a torque
wrench with suitable metric sockets are required for the
disassembly and assembly of the F11 series, plus common
hand tools.
