Motor installation
Direction of rotation
The V16 motor is bi-directional. Fig. 1 shows shaft rota-
tion vs. A or B port pressurized.
With inlet flow at port A the shaft turns counter clock-
wise (left hand, L, rotation), and with inlet flow at port B
the shaft turns clockwise (right hand, R, rotation).
Note:
Before installing the V16 in series (when the
A and B ports can be subject to high pressures
simultaneously) contact Parker Hannifin (Pump
& Motor Division Europe).
Filtration
Maximum motor service life is obtained when the flu-
id 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 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. A or B port pressurized).
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 20 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
Operating temperatures
The following temperatures should not be exceeded,
Main circuit: 80°C
Drain fluid: 115°C
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).
