PM/PMe50 - Variable displacement pump POCLAIN HYDRAULICS
OVERVIEW
PM/PMe50 is a variable displacement, axial piston pump, with swashplate system, for closed loop hydrostatic transmissions.
It provides a continuously variable flow rate between zero and maximum in forward and reverse direction. Flow rate is proportional to rotation
speed and swashplate angle.
It can feature a charge pump to keep the circuit pressurised. This avoids risk of cavitations and ensures a good performance of the transmission.
It offers several types of control: Hydraulic, electrical and electro-proportional. Hydraulic and electro-proportional ones can be equipped with feed-
back device.
It is equipped with high pressure relief valves and can be delivered with auxiliary gear pumps.
It is available in single or tandem versions.
As options, PM/PMe50 can be featured with flushing valve and filter on charge pressure line. As option, PM50 is equipped with onboard
SD-CT-30 and harness.

Charge pressure
A charge flow is required to maintain a positive pressure in the low pressure loop of a closed loop hydrostatic transmission. Charge
pressure ensures proper lubrication and rotating group operation. It is recommended to maintain the charge pressure at a minimum of
15 bar [218 PSI] above case pressure. For more details, refer to charge pump paragraph, page 18.
Case pressure
Case pressure must be maintained within the limits shown in the table ''Operating parameters''. Ensure housing is always filled with
hydraulic fluid and especially during start-up of the machine.
Pressure ratings
Maximum peak pressure
It is the maximum allowable pressure. It is equivalent to the maximum setting of the maximum high pressure relief valve. A self-propelled
machine can reach the maximum peak pressure value no more than 1-2% of that work cycle.
Work cycle
A fundamental factor for ensuring correct hydrostatic transmission sizing is the machine work cycle (pressure-time ratio, seasonality,
pressure vs. percentage of time at max. displacement, machine type). Part service life depends on the correct choice in relation to the
work cycle.
Overloads
It is mandatory to protect parts against any possible overloads.
Speed ratings
The table ''Operating parameters'' gives minimum and maximum rated speeds. Note that all displacements might operate under different
speed limits. Definitions of these speed limits appear below.
Maximum speed is the highest operating speed allowed. Over speeding reduces pump life time, can lead to loss of hydrostatic power and
braking capacity. Never exceed the maximum speed limit under any operating conditions.
Nominal speed is the speed offering the maximal efficiency.
12 31/10/2018
PM/PMe50 - Variable displacement pump POCLAIN HYDRAULICS
Inlet pressure
Charge pump inlet pressure is key for acceptable pump life and performances. A continuous inlet pressure of not less than 0,8 bar abs. [11.6
PSI abs.] is recommended. A continuous inlet pressure less than 0.5 bar abs. [7.2 PSI abs.] indicates inadequate inlet design or a restricted
filter. Pressures less than 0.5 bar abs. [7.2 PSI abs.] can happen at cold start, but should increase with oil temperature.
Theoretical output
Theoretical output flow is a function of pump displacement and speed. It is relevant to size the rest of the circuit. Theoretical flow does not take
into account losses due to leakage or variations in displacement. Refer to performances, page 6, for volumetric and overall efficiencies at
various operating speeds and pressures.
Poclain Hydraulics recommandations for fluid
Poclain hydraulics recommends the use of hydraulic fluids defined by the ISO 15380 and ISO 6743-4 standards.
For temperate climates, the following types are recommended.
• HM 46 or HM 68 for fixed installations.
• HV 46 or HV 68 for mobile installations.
• HEES 46 for mobile installations.
These specifications correspond to category 91H of the CETOP standard, parts 1, 2 and 3 of the DIN 51524 standard,
and grades VG32, VG 46 and VG68 of the ISO 6743-4 standards.
T
It is also possible to use ATF, HD, HFB, HFC or HFD type hydraulic fluid upon Poclain Hydraulics specific approval of the
components’ operating conditions.
Standardized designations for the fluids
• HM : Mineral fluids having specific antioxidant, anticorrosion and antiwear properties (HLP equivalent to DIN 51524
parts 1 and 2).
• HV : HM mineral fluids providing improved temperature and viscosity properties (DIN 51524 part 3).
• HEES :Biodegradable fluids based on organic esters.
It is also possible to use a fluid that meets the biodegradability criteria and is compatible in the event of
accidental food contact. The BIOHYDRAN FG 46 fluid designed by the company Total has undergone testing of
its properties and performance on our test benches. Since this type of fluid has not yet been categorized, it is the
responsibility of machine manufacturers to validate its compatibility with all of the components used in order to
guarantee that the intended functions will be fulfilled and this for the desired life time of all equipment items.
During operation, the temperature of the oil must be between 0°C [32°F] and 80°C [176°F]; the minimum and
maximum temperatures may be exceeded momentarily by ± 20°C [± 68°F] for a duration of less than 30 minutes.
For all applications outside these limits, please consult with your Poclain Hydraulics’ application engineer.
Pump storage
If the pump stays on stock for more than 6 months, a status verification must be performed before you install it on a
machine. Pay attention to sealing condition, rust presence and free rotation of shaft.
For biodegradable fluids, consult your Poclain Hydraulics’ application engineer

Fluid and filtration
The contaminating particles suspended in the hydraulic fluid cause the hydraulic mechanisms moving part wear. On hydraulic pumps,
these parts operate with very small dimensional tolerances. In order to reach the part life, it is recommended to use a filter that maintains
the hydraulic fluid contamination class at a max. of:
9 according to NAS 1638
20/18/13 according to ISO 4406:1999
According to the type of application decided for the pump, it is necessary to use filtration elements with a filtration ratio of:
ȕ 20 to 30 100
Making sure that this ratio does not worsen together with the increasing of the filter cartridge differential pressure.
If these values cannot be observed, the component life will consequently be reduced and it is recommended to contact the Poclain
Hydraulics Customer Service.
Filters on charge circuit
Filters on the charge circuit (F0-F2) are designed without by-pass. The max. pressure drop on the filtration part must not exceed 2 bar [29
PSI] (3 bar [43.5 PSI] in case of cold starting) at pump full rating. To monitor the pressure drop, It is recommended to use the clogging
indicator on the filtration element (F2 option). Contact your Poclain Hydraulics Application engineer, each time the pump is not charged by
its internal charge pump.
Filters on charge circuit are mounted on the pump special support.
Filters assembling
The suction filter is mounted on the suction line. Check that the pressure before the charge pump is 0.8 bar abs. [11.6 PSI abs.], measured
on the pump suction port (0.5 bar [7.2 PSI] for cold starting).
Viscosity range
For both max. efficiency and life of the unit, the operative viscosity should be chosen within the optimum range of:
¥opt = optimum operating viscosity from 16 to 36 mm
2
/s [from 74.1 to 166.8 SUS] referred to the closed loop temperature.
Working conditions: the following limits of viscosity apply
¥min = 5 mm

/s [23 SUS] short-duration at a max. permissible leakage oil temperature of 90° C [194°F]
¥max = 1000 mm

SYSTEM DESIGN PARAMETERS
Consult your Poclain Hydraulics application engineer to validate your
design parameters before using the pump in your application.
Sizing equations
The following equations are helpful when sizing hydraulic pumps. Generally, the sizing process is initiated by an evaluation of the machine
system to determine the required motor speed and torque to perform the necessary work function. First, the motor is sized to transmit the
maximum required torque. The pump is then selected as a flow source to achieve the maximum motor speed.

Loop flushing
Closed circuit may require a flushing valve to meet temperature and cleanliness requirements. A flushing valve takes a part of hot fluid flow from
the low pressure loop of the system loop for cooling and filtering. Make sure that the charge pump provides adequate flow for the flushing valve
flushing and the flushing valve does not cause charge pressure to drop below recommended limits.

Unintended vehicle or machine movement hazard.
The loss of hydrostatic drive line power, in any mode of operation (forward, neutral, or reverse)
may cause the system to lose hydrostatic braking capacity. You must provide a braking system,
redundant to the hydrostatic transmission, sufficient to stop and hold the vehicle or machine in
the event of hydrostatic drive power loss.

Reservoir
The reservoir provides clean fluid, dissipates heat, and removes entrained air from the hydraulic fluid. It allows for fluid volume changes
associated with fluid expansion and cylinder differential volumes. Minimum reservoir capacity depends on the volume needed to perform these
functions. Typically, a capacity of one half the charge pump flow (per minute) is satisfactory for a closed reservoir. Open circuit systems sharing a
common reservoir require greater fluid capacity.
Locate the reservoir outlet (suction line) near the bottom, allowing clearance for settling foreign particles. Use a 100 - 125 μm screen covering the
outlet port.
Place the reservoir inlet (return lines) below the lowest expected fluid level, as far away from the outlet as possible.
Use a baffle (or baffles) between the reservoir inlet and outlet ports to promote de-aeration and reduce fluid surging.
Case drain usage for tandem pump
To ensure lubrification of both pumps (with only one charge pump), excess flow from the second pump charge relief valve must be routed into
the housing of the first pump.
Differential pressure
The differential pressure is the High pressure relief valve setting minus Charge relief valve setting.
Tandem pumps with the option of opposing port
endcaps do not follow the above rule.

Bearing life and external shaft loading
Bearing life:
Bearing life is a function of speed, pressure , swashplate angle and external loads. Oil type and viscosity impact bearing life.
Shaft Loads
Normal bearing life in B
10
hours is shown in the above table. Figures have been calculated under the following operating conditions: A
continuous differential pressure of 150 bar [2 176PSI], 1 800 rpm shaft speed, maximum displacement, without any external shaft side load. The
data is based on a 50% forward, 50% reverse duty cycle, standard charge pump size, and standard charge pressure.
PM50 pumps are designed with bearings that can accept external radial and thrust loads. The external radial shaft load limits depend on the
load position, orientation, and operating conditions of the unit.
The maximum permissible radial load (Re), is based on the maximum external moment (Me), and the distance (L) from the mounting
flange to the load. It may be determined using the table and formula below. Thrust (axial) load limits are also shown.
Re = Me / L
All external shaft loads affect bearing life. In applications with external shaft loads, minimize the impact by positioning the load at 90° or 270° as
shown in the figure.
Contact your Poclain Hydraulics representative for an evaluation of unit bearing life if:
• Continuously applied external loads exceed 25 % of the maximum allowable radial load Re.
• The pump swashplate is positioned on one side of center all or most of the time.
• The unit bearing life (B
10
) is critical.

Hydraulic unit life
Hydraulic unit life is the life expectancy of the hydraulic components. It depends on speed and system pressure even if , system pressure
is the dominant operating variable. High pressure, generated by high load, reduces hydraulic unit life.
Design the hydraulic system according to the expected machine duty cycle. Take in consideration the expected percentages of time at
various loads and speeds. Ask your Poclain Hydraulics representative to calculate an appropriate pressure based your hydraulic system
design. If duty cycle data is not available, input power and pump displacement are used to calculate system pressure.
All pressure limits are differential pressures (referenced to charge pressure) , taking a normal charge pressure in consideration.
PM50 pumps will meet satisfactory life expectancy if applied within the parameters specified in this technical documentation. For more
detailed information on hydraulic unit life see Operating Parameters in page 9.
Mounting flange loads
Adding tandem mounted pumps, and/or tandem auxillary pump(s), subjecting pumps to shock loads may generate excessive loads on the
front mounting flange. The overhung load moment for multiple pump mounting can be estimated as shown in the figure bellow

FEATURES
High pressure relief valve
The High pressure relief valves maintain circuit pressure in the proper range. The check valves allow charge flow to replenish the low pressure
loop of the circuit. The high pressure relief valves ensure a high pressure protection of the high pressure loop of the circuit.
High pressure relief valves are available in a large range of settings. They are not adjustable.
When high pressure relief valves are not desired, pumps may be equipped with charge circuit check valves only. On request the setting of the
max displacement can be different, in this case two values must be indicated in order code (first for port A).
High pressure relief valves are intended for transient overpressure protection and are not
intended for continuous pressure control. Flow over relief valves for extended periods of time
may result in severe heat build up. High flows over relief valves may result in pressure levels
exceeding the nominal valve setting and potential damage to system components.

Charge relief valve
The charge pressure relief valve provides a relief outlet for charge circuit. This valve is used to set the charge pressure of the circuit. Flow
through the valve is ported to case.
The nominal charge relief setting is referenced to case pressure.
Incorrect charge pressure settings may result in the inability to build
required system pressure and/or inadequate loop flushing flows.
Ensure correct charge pressure under all conditions of operation to
maintain pump control performance.

PM/PMe50 - Variable displacement pump POCLAIN HYDRAULICS
Charge pump
Charge flow is required on all PM/PMe50 pumps used in closed circuit installations. The charge pump provides flow to make up internal
leakage, maintain a positive pressure in the main circuit, provide flow for cooling and filtration, replace any leakage losses from external valving
or auxiliary systems, and to provide flow and pressure for the control system.
Many factors influence the charge flow requirements. These factors include system pressure, pump speed, pump swashplate angle, type of
fluid, temperature, size of heat exchanger, length and size of hydraulic lines, control response characteristics, auxiliary flow requirements,
hydrostatic motor type, etc.
Unusual application conditions may require a more detailed review of charge pump sizing. Charge pressure must be maintained at a specified
level under all operating conditions to prevent damage to the transmission. Poclain Hydraulics recommends testing under actual operating
conditions to verify this.
Charge pump sizing / selection
In most applications a general guideline is that the charge pump displacement should be at least 20% of the main pump displacement.

PM/PMe50 - Variable displacement pump POCLAIN HYDRAULICS
Displacement limiters
PM50 are designed with mechanical displacement (stroke) limiters. You can limit maximum displacement of the pump to a certain per-cent of its
maximum displacement to near zero in both direction.
The displacement limiters are located on the both sides of the servo piston and are adjustable by screw. On request the setting of the max.
displacements can be different, in this case two values must be indicated in order code (first for port A).
By-pass
PM/PMe50 features a by-pass function. By-passing Port A and Port B is achieved by unscrewing a screw located on the cover. The by-pass
connect the ports A-B and must be use only in emergency case and only for short movement.
Take care in adjusting displacement limiters to avoid an undesirable condition of output flow
or speed. Retorque the sealing lock nut after every adjustment to prevent an unexpected
change in output conditions and to prevent external leakage during pump operation.

CONTROLS
Mechanical servo control with feed back (only for PM50)
The variation in pump displacement is obtained by rotating the drive lever situated on the servo control. An internal channel, linked to the
charge pump, feeds a hydraulic servo valve which supplies oil into the cylinder which is in turn linked to the pump swashplate.
The maximum rotation of the Iever, with respect to 0 is 40° for both rotation directions; thus permitting the optimum control of the
displacement.
The feedback function is obtained by a lever that connects the swashplate and the servo piston.
To avoid sudden accelerations and stoppages we introduce restrictors (Rs1 and Rs2) between the servo piston and the servo control.
The effort of moving the lever is independent of the pressure and rpm.

The variation in pump displacement is obtained by adjusting the pressure on the M3 and M4 servo control connections by means of a
hydraulic proportional joystick (containing pressure reduction valves).
The joystick supply can by obtained by taking pressure from the auxiliary pump (R connection).
The servo control response time can be adjusted by inserting a restrictor (Rs1 and Rs2) on the joystick supply line (from 0,6 to1,2 mm [from
0.02 to 0.05 in].
The servo control operation pressure curve in both control directions goes i.e 4,5 to 15 bar [i.e. 65 to 218 PSI]. The adjustment curve of the
hydraulic control system has to be wider (i.e. 4 to 16 bar [from 58 to 232 PSI]).
With PM50 S control we can provide some base Joy-stick (require dedicated documentation)

Hydraulic automotive control (only for PM50)
In relation to the input rotation rate, the pump swashplate positioning cylinder is actuated by the pressure of
the automotive valve progressively positioning the swashplate and a 4/3 electro-hydraulic valve determine
the direction. This provides a continuously variable pump displacement. The direction of the supplied flow is
determined by which of the two solenoids is energized.
The pilot pressure increases proportionally to the rotation pump. A pump displacement increase
corresponds to the higher pilot pressure.
In case the engine is overloaded, the rotation rate decreases and the pilot pressure is reduced causing a
pump displacement reduction with a corresponding drop in absorbed power.
An "Inching" lever is available to reduce the pilot pressure independently of the pump rotation speed (See
option IC page 79).

Electrical on-off servo control (only for PM50)
Control with return spring
The reaching of the maximum
displacement in a time defined by
the restrictors (Rs) which are
positioned between the
electrovalve and two chambers of
servo housing are obtained by the
continuous starting of an On-Off
electrovalve with an open-circuit
CETOP 2 connection.
If the electro-valve motion is
stopped, the pump goes back to
“0” position thanks to the servo
control springs.
The pump can be supplied either
without electrovalve (B00) or with
electrovalve (B12, B24 ).
Control without return spring
The variation in pump
displacement is obtained by the
energizing of an ON-OFF electro-
valve with a closed center CETOP
2 connection.
The displacement reached is in
relation to the starting time of the
electro-valve and to the diameter
of the Rs1and Rs2 restrictors
which are placed between the
electrovalve and the servo-control.
The pump can be supplied either
without electrovalve (C00) or with
electrovalve (C12, C24).
The servo control is without
springs and the setting of the
pump at a certain displacement is
guaranteed by the closed center of
the electrovalve.

SD-CT-30 checks that driver is present thanks to a seat switch.
When SD-CT-30 detects that driver is not on the seat, it stops the machine.
Ergonomics
When driver leaves his seat, machine stops accordingly to a parameter defined ramp. If driver is back before machine has stopped, to
avoid machine acceleration, brake security loop is engaged. The operator will first have to bring the joystick or travel pedal back to the
position matching the current vehicle speed to recover the full control of the speed.
Inputs/Outputs
• 1 digital input for reading the seat switch.
Temperature protection
Aim of the function
Protect the hydrostatic transmission against over temperature to preserve components lifetime.
Description
SD-CT-30 monitors temperature in transmission.
When temperature overpass a limit defined with a parameter, SD-CT-30 reduces machine speed to recover acceptable temperature.
Machine speed reduction is managed thanks to: • A reduction of the pump displacement.
• A reduction of the engine command.
The reduction ratios values are set by parameters.
Ergonomics
When system recovers acceptable temperature, reduction of machine speed is not more needed.
To avoid machine acceleration a brake security loop is engaged.The operator will first have to bring the joystick or travel pedal back to the
position matching the current vehicle speed to recover the full control of the speed.

CAN slave management
Usage sum up
CAN communication used by CAN slave is matching J1939 communication rules and frame definition. Used PGN are defined within
customer specific ID range.
To command the pump, following data are required:
• Pump direction (Neutral, direction A or direction B)
• Pump enable (Active or not)
• Pump command (in cc, with ramp management following parameter)
To improve safety of the command sent to the PMe pump throughout CAN bus, there is a counter that should be incremented each time a
new can frame is transmitted. This counter is 8bits long and is free running. It will return to 0 after 255. A second message will be sent as
redundancy purpose, it will contain one complemented data from main command frame. SD-CT-30 will check consistency between main
and redundancy CAN frame. In case of recurrent discrepancy PMe pump will enter in safe mode and bring pump back to neutral.
Conditions of CAN communication that can stop the pump:
• If main or redundant messages are missing for 0.5s, pump will go back to neutral following
a specific ramp (1.5s).
• If main and redundant messages are inconsistent 3 times (consecutively) pump will go
back to neutral following a specific ramp (1.5s).
• If counter of main message isn’t increasing, pump will go back to neutral following a specific
ramp (1.5s).
To ensure that redundant message will not be received before main message, redundant message will be sent at least 10ms after main
message.
After pump start-up an initial condition must be observed regarding the pump command to be able to stroke the pump. This initial condition
must be:
• Pump command = 0cc
• Pump enable = FALSE
• Pump direction = Neutral
To inform master SD-CT-30 of transmission condition, pump will send CAN frames containing pressure, speed, temperature information.
Those information will be transmitted in two ways:
• Physical values, computed using parameters value defining sensor characteristics.
• Electrical values that are direct RAW reading. Master SD-CT-30 will have to compute by its
..own physical values based on its own parameters. Master SD-CT-30 will also have to take
..care of signal range validity to detect sensor disconnection

Poclain Hydraulics has identified requirements for the controller, sensors and actuators to meet and satisfy the requirements of a
performance level d according to ISO 13849-1 (PLd) at the vehicle system. To quantify for a performance level d (PLd) it is imperative to
adhere to at least the following:
Installation and commissioning:
Maintenance and repair:
Precaution before maintenance and repair:
Operation after maintenance and repair:
Caution during electric welding:
Pump:
Starting up the engine:
Machine safety recomendations
A risk analysis must be conducted by the manufacturer to
ensure the non-hazardous nature of the machine in case of
failure on one of these components.
The safe state is opening of HSD and LSD (Pump coils). The
customer must realize a safety analysis of the machine to
check that there is no safety aspect due to the opening of the
HSD and LSD (Pump back to neutral).
Upon system design and configuration, it could be needed to
perform calibrations of safety critical inputs, to take into
account the complete measurement chain (physical imple-
mentation, sensor, harness, controller…).
Any maintenance or repair of the controller shall be done ac-
cording to the warranty terms. Otherwise, the integrity of the
controller and the effectiveness of safety principles can not be
guaranteed.
Before any maintenance or repair or decommissioning the
controller must be disconnected from the power source, in
particular before disconnecting interfaces connectors. To per-
form this operation, it is recommended to disconnect the bat-
tery fully after complete stop of the vehicle and its engine.
After maintenance or repair of the machine, it is necessary to
perform a calibration of the safety inputs.
The connectors on the controller and associated sensors
must be disconnected during the electric welding process.
The safety state of a hydrostatic transmission is stopped
vehicle by a rapid and mastered return to neutral of the pump.
To do so, it is necessary to add:
• restrictors to be correctly sized depending on the
application, the machine ... When using multi- displacements
motors, provide a bypass valve for these retrictors.
• A cut-off valve, allowing to bypass the supply of the pump.
Place the machine on the wheel blocks. Set up a safety area.
Observe all personnel safety instructions.

PM/PMe50 - Variable displacement pump POCLAIN HYDRAULICS
The pump can be equipped with analog temperature sensor.
Anti-stall valve (for PM/PMe50)
SD option consists a cartridge valve (same cartridge valve as automotive control) which provide a pressure signal for the servo piston of the
pump related to the speed of engine.
In case of engine overload and consequent rpm reduction the SD valve reduces the pressure for the servo piston and the pump de-stroke
consequentially with an anti-stall effect.

• For those messages SA value comes from “Own J1939 address in Slave” parameter.
Other available outputs
The pump can be equipped with sensors (temperature, pressure and speed). Their value will be sent on the CAN bus.
Two types of information on the CAN bus exist:
• Physical value (in V or Hz)
• Calculated value (in Bar or RPM or °C)
If the sensor voltage is out of valid range (0.5V - 4.5V), calculated value will be FFFFh. There is no management for sensors.
With Phases™ you have possibility to modify temperature and pressure parameters for sensors (Bar/Volt, Degree/Volt ...)
