Motor installation
Direction of rotation
The V14 motor is bi-directional. Fig. 1
shows shaft rotation vs. direction of ow.
When the A port is pressurized (black ar-
row) the motor 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 Par-
ker Hannin (Mobile Controls Div.).
Filtration
Maximum motor service life is obtained
when the uid cleanliness meets or ex-
ceeds ISO code 18/13 (ISO 4406).
A 10 µm (absolute) lter is recommended.
Case pressure
The lowest and highest recommended case
pressure (V14 with shaft seal type H or V)
at selected shaft speeds is shown in the
table below.
The min case pressure secures sufcient
lubrication, and the max case pressure,
which secures nominal seal life, should be
measured at the drain port.
Note: Contact Parker Hannin (Pump and
Motor Div.) for information on other shaft
seals.

Required inlet pressure
The motor operates as a pump under cer-
tain conditions. When this occurs, a mini-
mum pressure must be maintained at the
inlet port. Increased noise and gradually
deteriorating performance due to cavitation
may otherwise be experienced.
A 15 bar inlet pressure, measured at the
motor inlet port, satises most operating
conditions.
Contact Parker Hannin (Mobile Controls
Div.) for more specic information on inlet
pressure requirements.
Operating temperatures
The following temperatures should not be
exceeded (type H shaft seal):
Main circuit: 80 °C
Drain uid: 100 °C
FPM shaft seals (type V) can be used to
115 °C drain uid temperature.
Continuous operation at high power levels
usually requires case ushing in order for
the uid to stay above the minimum visco-
sity requirements.
A ushing valve and restricting nozzle, av-
ailable as an option, provide the necessary
main circuit ushing ow.
