Series V12

Series V12 is a bent-axis, variable displacement motor.

It is intended for both open and closed circuits, mainly

in mobile applications, but the V12 can also be utilized

in a wide variety of other applications.

Features

• Max intermittent pressure to 480 bar and continuous

operating pressure to 420 bar

• Thanks to low weight pistons with laminated piston

rings and a compact design of the rotating parts, the

V12 tolerates very high speeds

• High allowable speeds and operating pressures means

high output power; the overall efficiency remains high

throughout the entire displacement range

• The 9-piston design provides high start-uptorque and

smooth motor operation

• Wide displacement ratio (5:1)

• Broad range of controls and accessory valves for

most applications

• Small envelop size and a high power-to-weight ratio

• ISO, cartridge and SAE versions

• Low noise levels due to a very compact and sturdy

design with smooth fluid passages

• Positive piston locking, strong synchronizing shaft,

heavy-duty bearings and small number of parts add

up to a compact and robust motor with long service

life and proven reliability.

Series V14

Series V14 is a new generation of variable displace-

ment, bent-axis motors, a further development of our

well known V12 motor.

It is designed for both open and closed circuit trans-

missions with focus on high performance machines .

Applications

• Excavators

• Forestry machines

• Mining and drilling machines

• Wheel loaders

• Winch drives

Optional equipment

• Integrated sensors for speed and displacement

• Integrated flushing and pressure relief valves

Additional benefits (compared to those of the V12)

• Improved speed capability

• Improved control performance

• Reduced number of parts

• Stronger shaft bearing support.

T12

Series T12

The T12 two-displacement motor is tailor-made for

track drives. It allows a high ratio between high and

low speed and installs as easily as a fixed displace-

ment motor. Max speed ratio is 3.33-to-1.

The T12 is a cartridge motor based on the well proven

V12 series. The specially designed end cap with dual

side ports permits a very short installation.

A simple setting device moves the cylinder barrel to

the maximum or minimum displacement position. The

setting is controlled by an external hydraulic pilot signal.

A brake valve can be fitted without increasing the axial

length of the motor. The twin ports have the same

mounting pattern as those of the F12 and V12 motors.

The F12/V12 accessory valve program also fits the

T12 motor. As an option, integrated pressure relief

valves can be included.

Bearing life

General information

Bearing life can be calculated for that part of the load/

life curve (shown below) that is designated ’Bearing

fatigue’. ’Fatigue of rotating parts’ and ’Wear’caused by

fluid contamination, etc., should also be taken into consi-

deration when estimating the service life of a motor/pump

in a specific application.

In reality, bearing life can vary considerably due to the

quality of the hydraulic system (fluid condition, cleanli-

ness, etc.)

Bearing life calculations are mainly used when com-

paring different motor frame sizes. Bearing life, desig-

nated B

(or L

), depends of system pressure, opera-

ting speed, external shaft loads, fluid viscosity in the

motor case, and fluid contamination level.

The B

value means that 90% of the bearings survive

at least the number of hours calculated. Statistically,

50% of the bearings will survive at least five times the

life.

Bearing life calculation

An application is usually governed by a certain duty or

work cycle where pressure, speed and displacement

vary with time during the cycle.

Bearing life is also dependent on external shaft loads,

case fluid viscosity and fluid contamination.

Parker Hannifin has a computer program for bearing

life calculation and will assist in determining life for

specific V12 load conditions; refer to MI 170, ‘V12

bearing life’, available from Parker Hannifin.

Required information

When requesting a bearing life calculation from Parker

Hannifin, the following information (where applicable)

should be provided:

- A short presentation of the application

AC pressure compensator

The AC compensator is used in off-road vehicle hydro-

static transmissions; it automatically adjusts motor dis-

placement to the output torque requirement (up to max

available system pressure).

Normally, the motor stays in the minimum displacement

position. When there is a demand for additional torque,

i.e. when the vehicle enters an upgrade, the displace-

ment increases (providing more torque) while the motor

shaft speed decreases proportionally.

The threshold pressure (‘p

’; refer to the AC diagram)

where displacement starts to increase, is adjustable

between 150 and 400 bar.

To reach max displacement, an additional modulating

pressure (∆p) above the threshold pressure (p

) is

required.

To satisfy specific hydraulic circuit requirements, a

modulating pressure, ∆p, of 15, 25 or 50 bar can be

selected.

The AC compensator is available in two versions:

ACI 01 I - Internal pilot pressure

ACE 01 I - External pilot pressure; port X5 can, for

(optional) example, be connected to the ’forward

drive’ pressure line of a vehicle trans-

mission to prevent motor displacement

increase when the vehicle is going downhill.

Gauge/pilot ports (AC compensator):

X1 Setting piston pressure (increasing displ.)

X2 Servo supply pressure (after orifice)

X4 Servo supply pressure (before orifice)

X5 External pilot pressure

X6 Setting piston pressure (decreasing displ.)

Ports are:

– M14x1.5 (ISO and cartridge versions)

–

"-18 O-ring boss (SAE version).

Servo supply pressure is usually obtained from the main

high pressure port through the built-in shuttle valve.

When using external servo supply, the servo pressure

should be at least 30 bar.

The response time (i.e. from max to min displacement)

is determined by orifices in the servo valve supply and

return lines.

NOTE: Control ordering codes are shown on page 13

and installation dimensions on page 27.

Controls (general information)

The following six V12 controls described below satisfy

most application requirements:

• Pressure compensator (AC and AH)

• Two-position controls (EO and HO)

• Proportional controls (EP and HP).

All controls utilize a setting piston that connects to the

valve segment (refer to the picture on page 8).

The built-in four-way servo valve acts on the setting

piston and determines the displacement which can

vary between 35° (max) and 6.5° (min).

AH pressure compensator

The AH compensator is similar to the AC (page 21) but

incorporates an hydraulic override device. It is utilized in

hydrostatic transmissions where a high degree of

manœuvrability at low vehicle speeds is desirable.

When the override is pressurized, the servo piston moves

to the max displacement position irrespective of system

pressure, provided the servo supply pressure is at least

30 bar.

The AH compensator is available in two versions:

AHI 01 I - Same as the ACI except for the override;

internal pilot pressure.

AHE 01 I - External pilot pressure (port X5; compare

(optional) ACE, page 21).

EO two-position control

The EO is a two-position control, where max and min dis-

placements are governed by a DC solenoid attached to

the control cover (refer to the installation drawing on

page 27).

The EO control is utilized in transmissions where only

two operating modes are required: Low speed/high torque

or high speed/low torque.

The servo piston, normally in the max displacement

position, shifts to the min displacement position when

the solenoid is activated. Intermediate displacements

cannot be obtained with this control.

Servo pressure is supplied internally (through the shuttle

valve from one of the main high pressure ports) or exter-

nally (port X4).

The solenoid is either 12 or 24 VDC, requiring 1.2 and

0.6 A respectively. An electrical connector is included

(DIN 43650/IP54).

The EO two-position control is available in four versions:

EOH 01 I - Internal servo supply, 24 VDC

EP proportional control

The EP electrohydraulic proportional control is used in

hydrostatic transmissions requiring a continuously vari-

able shaft speed. The servo valve is governed by a DC

solenoid attached to the control cover.

When the solenoid current increases above the thresh-

old current, the servo piston starts to move from the

max towards the min displacement position. The dis-

placement vs. solenoid current is shown in the diagram

to the right. Please note, that the shaft speed vs. current

is non-linear; refer to the diagram below.

Solenoids are available in 12 and 24 VDC versions,

requiring a max current of approx. 1.1 and 0.55 A

respectively.

The threshold current (I

) is factory set (0.4 A at 12 VDC/

0,2 A at 24 VDC) but is adjustable (12 VDC: 0.25–0.45 A;

24 VDC: 0.10–0.23 A).

When utilizing the full displacement range, the required

modulating current (∆I) is 0.6 and 0.3 A respectively. In

order to minimize hysteresis, a pulse-width modulated

control signal of 70 to 90 Hz should be utilized.

NOTE: The modulating current (∆I) is not adjustable.

The EP control is available in four versions:

EP H 01 I - Internal servo supply, 24 VDC

EP L 01 I - Internal servo supply, 12 VDC

EP H 01 E - External servo supply, 24 VDC

(optional)

HO two-position control

The two-position HO control is similar to the EO (page

23) but the pilot signal is hydraulic. The position of the

setting piston is governed by the built-in servo valve

(same on all compensators and controls).

When the applied pilot pressure (port X5) exceeds the

pre-set threshold pressure, the piston moves from the

max to the min displacement position.

The threshold pressure is factory set at 10 bar but can

be adjusted between 5 and 25 bar.

The HO two-position control is available in two versions:

HO S 01 I - Internal servo supply

HO S 01 E - External servo supply (port X4)

HP proportional control

Like the EP control described on page 24, the HP pro-

portional control offers continuously variable displace-

ment, but the pilot signal is hydraulic.

Normally, the servo piston stays in the max displace-

ment position. When a sufficiently high pilot pressure

) is applied to port X5, the piston starts to move

towards the min displacement position.

As can be seen in the diagram to the right, the displace-

ment changes in proportion to the applied modulating

pressure.

In contrast, shaft speed vs. pilot pressure is non-linear;

refer to the diagram below.

The following modulating pressures (∆p) can be se-

lected: 15 or 25 bar.

The threshold pressure (p

) is factory set at 10 bar but

is adjustable between 5 and 25 bar.

Two versions of the HP control are available:

HPS 01 I - Internal servo supply

Flushing valve

As an option, L, the V12 is available with a flushing (or

shuttle) valve that supplies the motor with a cooling flow

through the case. Cooling the motor may be required

when operating at high speeds and/or power levels.

The flushing valve consists of a three-position, three-

way spool valve built into a special end cap. It connects

the low pressure side of the main circuit to a nozzle

(optional size) that empties fluid into the motor case.

In a closed circuit transmission, the flushing valve

removes part of the fluid in the main loop. The removed

fluid is continuously being replaced by cool, filtered fluid

from the low pressure charge pump on the main pump.

NOTE: The flushing valve ordering code is shown on

page 13 (‘L 01’).

Accessory valve blocks

SR pressure relief/check valve

To protect the main hydraulic circuit from unwanted

pressure peaks, an add-on valve block, type SR, with

two independent pressure relief cartridges and two

large capacity check valves can be ordered for series

V12.

The valve block is mounted on the motor end cap as

shown to the right. The individual cartridge has a fixed,

factory-set opening pressure.

An external port for make-up fluid is provided. When

sufficiently pressurized, it prevents motor cavitation due

to pressure losses in the main circuit.

For additional information, refer to ‘Mobile motor/pump

accessories’ (catalogue HY17-8258/UK).

SV pressure relief valves

The SV relief valve block is an alternative to the SR

valve block above.

The SV contains the same cartridge valves as the SR

but lacks the two check valves; refer to the SV sche-

matic, below, and to ‘Mobile motor/pump accessories’

(catalogue HY17-8258/UK).

BW2/SX2 brake/relief valves

In applications, such as open circuit wheel drives, a

counterbalance or ‘brake’ valve is required. It provides

smooth braking and greatly reduces the risk of motor

cavitation when coasting or braking.

Brake/relief valves, type BW2/SX2, are available for

series V12 motors. The two valve blocks mount directly

on the motor end cap as shown to the right.

As an option, size BW23 can be supplied with a make-

up port; when sufficiently pressurized, motor cavitation

due to pressure losses in the main circuit is being pre-

vented.

For additional information, refer to ’Mobile motor/pump

accessories’ (catalogue HY17-8258/UK).

Speed sensor

A speed sensor kit is available for the I and S versions

of series V12.

The ferrostat differential (Hall-effect) sensor installs in

a separate, threaded hole in the V12 bearing housing.

The speed sensor is directed towards the V12 shaft

flange and outputs a square wave signal within a fre-

quency range of 5 Hz to 20 kHz. Number of pulses per

shaft rev is 36 which, at 5 Hz, corresponds to approx.

8 rpm.

When a ‘Speed sensor’ is ordered (refer to the ordering

codes on pages 10 and 12), the housing is machined

with the threaded hole; the speed sensor kit is deliv-

ered in a separate bag.

NOTE: - The motor bearing housing must be prepared

for the speed pick-up; refer to the V12 ordering

codes on pg. 10 and 12.

- Additional information is provided in our pub-

lication ‘Mobile motor/pump accessories’

Servo supply pressure is obtained from the pressu-

rized, main port through the corresponding, built-in

shuttle valve.

The response time (i.e. from max-to-min or from min-

to-max displacement) is determined by restrictor nozzles

in the servo valve supply and return lines; refer to the

schematics.

Controls - general information

The following V14 controls satisfy most application

requirements:

• AC, AD and AH (automatic pressure compensators)

• 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 32).

The built-in four-way servo valve determines the posi-

tion 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).

AC compensator function (cont’d)

The AC compensator is used in off-road vehicle hydro-

static propel transmissions. The compensator automati-

cally adjusts motor displacement between available

max and min to the output torque requirement (up to

max available system pressure).

Normally, the motor stays in the minimum displace-

ment position. When there is a demand for additional

torque, e.g. when the vehicle enters an upgrade, the

displacement increases (providing more torque) while

the motor shaft speed decreases proportionally.

The threshold pressure, where displacement starts to

increase (‘p

’; refer to the AC diagram), is adjustable

between 100 and 400 bar.

To reach max displacement, an additional modulating

pressure (∆p) above the threshold pressure is required.

To satisfy specific hydraulic circuit requirements, a

modu-lating pressure of 15 or 50 bar can be selected.

The pressure compensator is supplied with a small

filter installed in the AC control cover (between ports

X4 and X5); refer to the schematic below right.

AD pressure compensator

The AD control is similar to the AC (shown on previous

pages) but incorporates a solenoid controlled override

function and a brake defeat valve.

Override

- The override consists of a piston built into a special

end cover and an external solenoid.

- When the solenoid is energized, system pressure is

directed to the piston which in turn pushes on the

spool of the servo control valve. This causes the motor

to lock in the max displacement position, irrespective

of system pressure (min 30 bar).

- Solenoids are available in 12 VDC (designated L)

and 24 VDC (design. H); the required current is 2 and

1 A respectively.

Brake defeat valve

- The brake defeat function, which is also built into the

special end cover, consist of a two-position, three-way

valve. Ports X9 and X10 (refer to the schematic) are

connected to the corresponding ports of the pump

displacement control.

- The function prevents any pressure in the motor return

port to influence the pressure compensator. Say, e.g.,

that motor port A is pressurized to move the vehicle

‘forward’. Thus, back pressure in return port B, which

develops in the braking mode, will not cause the com-

pensator to move towards the max displacement posi-

tion and vehicle braking will be smooth.

- Likewise, when port B is pressurized when the vehicle

moves ‘backward’, braking presssure in port A will

not influence the compensator.

AH pressure compensator

The AH compensator is similar to the AD (shown on

previous page) but incorporates only an hydraulic over-

ride device. It is utilized in hydrostatic transmissions

where a high degree of manœuvrability at low vehicle

speeds is desirable.

When the override is pressurized, the servo piston moves

to the max displacement position irrespective of system

pressure, provided the servo supply pressure is at

least 30 bar.

Basically, these controls function in a similar way.

At increasing solenoid current (EP) or increasing pilot

pressure (HP) the control moves towards the min dis-

placement position.

At decreasing current or pilot pressure, the control

retracts towards max displacement.

In comparison with EP and HP, the EO and HO con-

trols have no modulating spring; this means that only

min and max displacements can be obtained with these

controls.

Max and min displacements can be limited by a screw

EP control function (solenoid current increasing)

NOTE: Valid also for the HP at increasing pilot pressure.

Refer to the illustration below left:

At an increasing current (above the threshold value),

the solenoid spool pushes left on the servo valve spool,

and flow is directed to the left hand setting chamber -

the setting piston moves to the right and the displace-

ment decreases. This means, that the shaft speed in-

creases while the output torque decreases correspond-

ingly (at a constant pump flow and system pressure).

HP control function (decreasing pilot pressure)

NOTE: Valid also for the EP at decreasing current.

Refer to the illustration below right:

When the pilot pressure decreases, the servo valve

spool moves to the right and flow is directed to the right

hand setting chamber - the setting piston moves to the

left and the displacement increases.

The shaft speed now decreases and the available

output torque increases correspondingly (at a constant

EO electric two-position control

- The EO is a two-position control where the max and

min displacements are governed by a DC solenoid

(acting on the servo spool) which is attached to the

control module (refer to the illustration on page 42).

- The EO is utilized in transmissions where only two

operating modes are required - low speed/high torque

and high speed/low torque.

- The servo piston, normally in the max displacement

position, shifts to min displacement as soon as the

solenoid is activated.

- Intermediate displacements cannot be obtained

with this control.

- Servo pressure is supplied internally (through a check

valve from the utilized high pressure port); refer to

the schematic below.

- The solenoid is either 12 or 24 VDC, requiring 1 .2

and 0.6 A respectively. The male connector (type

’Junior Timer’) is permanently installed on the sole-

noid. The corresponding female connector is delivered

separately in a bag with the motor; it is also available

as a spare part, P/N 378 1939.

- The threshold current of the 12 VDC solenoid is fac-

tory set at 400 mA; it is adjustable between 200 and

500 mA. The 24 VDC solenoid is factory set at 200 mA

and is adjustable between 100 and 250 mA.

EP electrohydraulic proportional control

- The EP electrohydraulic proportional control is used

in hydrostatic transmissions requiring a continuously

variable shaft speed. The servo valve is governed by

a DC solenoid (acting on the servo spool), attached to

the control module (refer to the illustration on page 42).

- When the solenoid current increases above the thresh-

old value, the servo piston starts to move from max

towards min displacement. The displacement vs.

solenoid current is shown in the diagram below.

NOTE: The shaft speed is not proportional to the

solenoid current; refer to the bottom diagram.

- The solenoid (which is the same as the one used on

the EO control) is either 12 or 24 VDC, requiring 1200

and 600 mA respectively.

- The male connector (type ‘Junior Timer’) is perma-

nently installed on the solenoid. The corresponding

female connector is delivered in a separate bag with

the motor; it is also available as a spare part:

P/N 378 1939.

- The threshold current of the 12 VDC solenoid is fac-

tory set at 400 mA; it is adjustable between 200 and

500 mA. The 24 VDC solenoid is factory set at 200 mA

and is adjustable between 100 and 250 mA.

- When utilizing the full displacement range, the required

modulating current (∆I) is 0.6 and 0.3 A respectively.

In order to minimize hysteresis, a pulse-width modula-

ted control signal of 50 to 60 Hz should be provided.

ment position. When a sufficiently high pilot pressure

) is applied to port X5, the piston starts to move

towards the min displacement position.

- As can be seen from the pilot pressure/displacement

• Pressure relief valves (option P; page 54)

Brake valve and pressure relief valves

(option B)

In applications, such as open circuit excavator wheel

drives, a counterbalance or ‘brake’ valve is normally

required.

The BW22 brake valve provides smooth braking and

reduces the risk of motor cavitation when the vehicle is

in a coasting or braking mode.

The BW22 brake valve block installs directly on the

motor connection module as shown in the illustration.

The ’S’ port is provided for supply of make-up fluid;

when sufficiently pressurized, motor cavitation due to

pressure losses in the main circuit is greatly reduced.

PLEASE NOTE:

1. In order to obtain the intended performance, the

BW22 valve must be properly matched to the

hydraulic system of a particular vehicle.

When considering utilizing this valve, contact

Parker Hannifin who will assist in the specification

and testing.

2. As a first step, a ‘BW2 brake valve specification

form’ (MI 118) should be requested, filled in and

sent to Parker Hannifin. With this information, a

valve, suitable for testing, can then be specified.

Sensor options (overview)

• Shaft speed sensor (option S; page 53)

• Setting piston position sensor (option L; page 55)

Additional BW22 brake valve information is available in

’Mobile motor/pump accessories’, cat. HY17-8258/UK.

Pressure relief (cartridge) valves are included when

ordering ‘option B’. The relief valves are integrated in

the V14 motor (as shown in the illustration above).

Detailed information is shown on page 54 (‘option P’).

Flushing valve (option L)

The V14 is available with a flushing (or shuttle) valve

that supplies the motor with a cooling flow through the

case. Cooling the motor may be required when operat-

ing at high speeds and/or power levels.

The flushing valve consists of a three-position, three-

way spool valve built into the connection module. It con-

nects the low pressure side of the main circuit to a nozzle

(optional sizes below) that empties fluid into the motor

case.

In a closed circuit transmission, the flushing valve re-

moves part of the fluid in the main loop. The removed

fluid is continuously being replaced by cool, filtered fluid

from the low pressure charge pump on the main pump.

Shaft speed sensor (option S)

A speed sensor kit is available for the V14.

The ferrostat differential (Hall-effect) sensor installs in

a separate, threaded hole in the V14 bearing housing.

The speed sensor is directed towards the V14 shaft

flange and outputs a square wave signal within a fre-

quency range of 5 Hz to 20 kHz. Number of pulses per

shaft rev is 36 which, at 5 Hz, corresponds to approx.

8 rpm.

Pressure relief valves (option P)

To protect the motor (and the main hydraulic circuit)

from unwanted, high pressure peaks, the V14 can be

supplied with relief valve cartridges.

The individual cartridge (with integrated check valve

function) has a non-adjustable, factory-set opening

pressure, available in pressure settings shown below.

The cross section (below right) shows a situation, where

the upper cartridge has opened because of high fluid

pressure. This, in turn, forces the opposite cartridge to

open to the low pressure area (this cartridge now acting

as a check valve).

As shown, a small part of the flow may go directly to

the reservoir.

PLEASE NOTE:

- The pressure relief cartridges should not be used as

main pressure reliefs; in a motor application, they

should only be relied on to limit short duration pres-

sure peaks (or the temperature of the fluid which cir-

culates through the motor will rapidly reach damaging

high levels).

- The main pressure relief is usually installed in the

main pump or in the directional control valve, or is

line mounted between pump and motor.

Setting piston position sensor (option L)

NOTE: The position sensor is available only in

connection with the EP control.

The setting piston position sensor, also referred to as a

’Sub-Miniature In-Cylinder Transducer’, combines the

best features associated with LVDT’s (Linear Variable

Differential Transformer) and potentiometers into one

rugged, contactless, highly reliable position sensor.

The stationary part of the sensor, the sleeve, is pro-

vided with a flange that fits in a specially machined

boring in the control module housing.

The movable shaft of the sensor is attached to the

feedback arm as shown in the illustration to the right.

When the sensor is properly connected to the electronic

module (packed separately with an installation sheet),

the produced output signal is proportional to the position

of the setting piston.

In order to obtain the correct electrical max and min

position settings, as determined by the utilized max

and min displacements, the programming module (part

of the electronic module, illustrated below right) must

be adjusted; refer to the detailed installation information

available from Parker Hannifin.

Direction of rotation versus flow

NOTE: The V12, V14 and T12 motors are bi-directional.

V12 rotation:

- End cap position T (AC, AD and AH controls): When

port B (open arrow) is pressurized, the motor rotates

clockwise (right hand; R), and when port A (black arrow)

is pressurized, the motor turns counter clockwise (left

hand; L)

- End cap position M (EO, EP, HO and HP controls):

A and B port positions interchange (A-to-B, B-to-A).

V14 rotation:

- Refer to the V14 illustration below right (valid for all

compensators and controls).

T12 rotation:

- Refer to the V14 illustration below right.

NOTE: Before installing a V12, V14 or T12 motor in

series (when both A and B ports can be subject

to high pressures simultaneously) contact

Parker Hannifin.

Filtration

Maximum motor sevice life is obtained when the fluid

cleanlineness 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

(shaft seal type H) at selected shaft speeds is shown in

the table below.

The min pressure secures sufficient lubrication, and the

max pressure nominal seal life.

Case pressure should be measured in the drain port.

NOTE: Contact Parker Hannifin for information when

operating at high speeds.

Min and max case pressure [bar] vs. shaft speed [rpm].

NOTE: Contact Parker Hannifin for information on

other shaft seals.

Required inlet pressure

The motor may operate 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 cavita-

tion may otherwise be experienced.

A 15 bar inlet pressure, measured at the motor inlet

port, satisfies most operating conditions.

Contact Parker Hannifin for more specific information on

inlet pressure requirements.

Operating temperatures

The following temperatures should not be exceeded

(type H shaft seal):

Main circuit: 80 °C.

Drain fluid: 100 °C.

FPM shaft seals (fluorocarbon; 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 requirement. A flushing

Drain ports

There are two drain ports on the V12, V14 and T12

motors. The uppermost drain port should always be

utilized (see illustrations on the previous page).

In order to avoid excessively high case pressure, the

drain line should be connected directly to the reservoir.

When the motor is operating, the case must be filled

with fluid to at least 50%.

NOTE: - A spring loaded check valve in the drain line

(shown in the V14 illustrations to the right) may

have to be installed in order to prevent oil from

being siphoned out of the motor case. This can

otherwise happen if, e.g., the reservoir is loca-

ted below the utilized motor drain port.

- ‘High speed operation’ available from

Parker Hannifin.

Hydraulic fluids

Ratings and performance data for the motors are valid

when a good quality, contamination-free, petroleum-

based fluid is used in the hydraulic system.

Hydraulic fluids type HLP (DIN 51524), automatic trans-

mission fluids type A, or API CD engine oils can be used.

When the hydraulic system has reached full operating

temperature, the motor drain oil viscosity should be

above 8 mm

/s (cSt).

At start-up, the viscosity should not exceed 1500 mm

/s.

The ideal operating range for the motor is 15 to 30 mm

/s.

Fire resistant fluids, when used under modified opera-

ting conditions, and synthetic fluids are also suitable.

Contact Parker Hannifin for additional information about:

- Hydraulic fluid specifications

- Fire resistant fluids.

Before start-up

Make sure the motor case as well as the entire hydrau-

lic system is filled with hydraulic fluid.

The internal leakage, especially at low operating pres-

sures, is not sufficient to provide lubrication at start-up.
