Series V14
General information Important features carried over from previous motors:
Series V14 is a new generation of variable displacement motors developed and manufactured by Parker Hannifin, Pump and
Motor Division.
The V14 is a further development of our well known V12 motor. It is designed for both open and closed circuits, intended particularly for mobile applications.
•
•
Operating pressures to 480 bar
• High speeds, thanks to low weight pistons with laminated piston rings and a very compact design of the rotating parts.
High overall efficiency throughout the entire displacement range
New features:
• Increased shaft speeds
• Improved sealing
• Faster control response
• Improved shaft support
• Additional integrated functions added
• New control, HPC, for winch
...mainly thanks to:
• 9 pistons provide high start-up torque and smooth operation
•
•
Wide displacement range - 5:1
Small envelope size and high power-to-weight ratio
•
• Low noise levels due to the compact, sturdy design and smooth fluid
passages
Positive piston locking, strong synchronizing shaft, heavy-duty bearings and a small number of parts add up to a very robust motor with long service life and proven reliability.
•
•
• Re-designed piston
• O-ring seals between housings
• Enlarged setting piston
Increased size control device
Tapered roller bearings

Motor installation
Direction of rotation
The V14 motor is bi-directional. Fig. 1 shows shaft rotation vs. direction of flow.
Port A
Port B
When the A port is pressurized (black arrow) 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 Parker Hannifin (Mobile Controls Div.).
Filtration
Maximum motor service life is obtained when the fluid cleanliness meets or exceeds ISO code 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 H or 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 conditions. When this occurs, a minimum 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, satisfies most operating conditions.
Contact Parker Hannifin (Mobile Controls
Div.) for more specific information on inlet pressure requirements.
Note: For high speed info, see Marketing information database.
Operating temperatures
The following temperatures should not be exceeded (type H shaft seal):
Main circuit: 80 °C
Drain fluid: 100 °C
FPM shaft seals (type V) can be used to
115 °C drain fluid temperature.
Continuous operation at high power levels usually requires 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).

Pump and Motor Division
Trollhättan, Sweden www.comoso.com
Bulletin HY30-5510-M1/UK
Drain ports
There are two drain ports on the V14; the uppermost drain port should always be utilized (fig. 3).
In order to avoid excessively high case pressure, the drain line should be connected directly to the reservoir.
NOTE: When the motor is operating, the case must be filled with fluid to at least
50%.
Hydraulic fluids
Ratings and performance data for series
V14 motors are valid when a good quality, contamination-free, petroleum-based fluid is used in the hydraulic system.
Service Manual
Series V14
Note:
A drain line spring loaded check valve (shown in fig. 2, 3 and 4) may have to be installed in order to prevent oil from being siphoned out of the motor case. This can otherwise happen e.g. if the reservoir is located below the utilized motor drain port.
Flushing valve
(optional)
Drain and cooling flow to reservoir
Check valve
Hydraulic fluids type HLP (DIN 51524), automatic transmission fluids type A, or API
CD engine oils can be used.
Fire resistant fluids, when used under modified operating conditions, and synthetic fluids are also suitable.
When the hydraulic system has reached full operating temperature, the motor drain oil viscosity should be above 8 mm²/s (cSt).
At start-up, the viscosity should not exceed
1500 mm²/s.
The ideal operating range for the V14 series is 15 to 30 mm²/s.
The following information (available from
Parker Hannifin, Pump and Motor Div.) provide additional information about:
- Hydraulic fluid specifications
- Fire resistant fluids
Before start-up
Make sure the motor case as well as the entire hydraulic system is filled with hydraulic fluid. The internal leakage, especially at low operating pressures, is not sufficient to provide lubrication at start-up.

Controls - general information
The following controls satisfy most application requirements:
• AC (automatic pressure compensator)
• AD (Automatic pressure compensator with
electric override and brake defeat)
• AH (automatic pressure compensator with
hydraulic override)
• EO and HO (two position controls)
• EP and HP (proportional controls)
All controls utilize a servo piston that connects to the valve segment (refer to the illustration on page 4).
The built-in four-way servo valve determines the position of the servo piston and, in turn, the displacement.
The displacement angle (between output shaft and cylinder barrel) ranges from 35°
(max) to 6.5° (min).
Servo supply pressure is obtained from the pressurized, main port through the corresponding, built-in shuttle valve.
The respons time (i.e. from max-to-min or from min-to-max displacement) is determined by restrictors in the servo valve supply and return lines; refer to the schematics.

Test procedure
Use a test stand that supplies a flow of about 30 l/min. and pressures of up to 300 bar.
A secondary flow of 3-5 l/min. at a pressure of 25 bar is required to supply low pressure for externally supplied controls.
EP control requires an amplifier supplying correct current according to specification.
Test
1. Fill housing with hydraulic fluid and start the pump in the test stand.
2. Increase the pressure with the restrictor valve on the return line. Max allowed pressure is 150 bar / 2150 psi.
3. Check the drain flow and compare with the table.
