Motor installation
Direction of rotation
The V14 motor is bi-directional. Fig. 1 shows shaft rota-
tion vs. direction of flow.
When the A port is pressurized (black arrow) the mo-
tor turns counter clockwise (left hand, L, rotation), and
when the B port is pressurized (open arrow) the shaft
turns clockwise (right hand, R, rotation).
Note:
Before installing the V14 in series (when the
A and B ports can be subject to high pressures
simultaneously) contact Parker Hannifin (Pump
& Motor Div.).
Filtration
Maximum motor service life is obtained when the fluid
cleanliness meets or exceeds ISO code 20/18/13 (ISO
4406).
A 10 μm (absolute) filter is recommended.
Case pressure
The lowest and highest recommended case pressure
(V14 with shaft seal type
V
) at selected shaft speeds is
shown in the table below.
The min case pressure secures sufficient lubrication,
and the max case pressure, which secures nominal seal
life, should be measured at the drain port.
Fig. 1 (motor rotation vs. direction of flow).
Required inlet pressure
The motor operates as a pump under certain condi-
tions. When this occurs, a minimum pressure must be
maintained at the inlet port. Increased noise and gra-
dually deteriorating performance due to cavitation may
otherwise be experienced.
A 15 bar inlet pressure, measured at the motor inlet
port, satisfies most operating conditions.
Contact Parker Hannifin (Pump & Motor Div.) for more
specific information on inlet pressure requirements

database
Operating temperatures
The following temperatures should not be exceeded,
FPM shaft seal (type V) can be used to 115°C drain fluid
temperature.
Continuous operation at high power levels usually re-
quires case flushing in order for the fluid to stay above
the minimum viscosity requirements.
A flushing valve and restricting nozzle, available as an
option, provide the necessary main circuit flushing flow.
Refer to fig. 2 (next page).
