PMV0 - Variable displacement pump POCLAIN HYDRAULICS
OVERVIEW
PMV0 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 directions. 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 cavitation and ensures a good transmission performance.
It offers two types of control: direct-mechanical and servo-hydraulic.
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, PMV0 can be featured with flushing valve, filter on charge pressure line and safety devices to ensure safe operation of the machine.

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 6
bar [87 psi] above case pressure. In case of direct mechanical control (M), charge pressure must be set at 10 bar [145 PSI] mini. In case
of servo control (S), charge pressure must be set at 20 bar [290 PSI]. For more details, refer to charge pump paragraph, page 20.
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.
PMV0 - Variable displacement pump POCLAIN HYDRAULICS
12 07/07/2025
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. An 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.
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:
6 according to NAS 1638
20/18/13 according to ISO 4406
According to the type of application decided for the pump, it is necessary to use filtration elements with a filtration ratio of:
β 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.

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

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,

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
On tandem pumps, and to ensure lubrification of both pumps, 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.

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 120 bar [1 740 PSI], 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 (20 bar [290 PSI]).
PMV0 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.
PMV0 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 11.
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

*Calculations will be carried out by multiplying the gravity (g = 9.81 m/sec²) with a given factor. This factor depends on the application.
Allowable overhung load moments are shown in the table below. Values in the table are valid for all displacements. Exceeding these
values requires additional pump support.

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 range of settings.
When high pressure relief valves are not desired, pumps is equipped with charge circuit check valves only.
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.

Charge pump
Charge flow is required on all PMV0 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.
Consult your Poclain Hydraulics application engineer for more information.

Displacement limiters
PMV0 with hydraulic servo control (S) 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 is possible to set
different max. displacement. First displacement for output flow on port A.
By-pass
See ’’Options’’ chapter page 36 and page 37 for more information.
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.

Hydraulic servo control
The variation in pump displacement is obtained by adjusting the pressure on the M3 and M4 or M5 and M6 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 (G connection).
The servo control timing can be adjusted by inserting a restrictor on the joystick supply line (from 0.5 to1,2 mm [from 0.02 to 0.05 in]) or
between the joystick and servo piston of the pump.
The servo control operation curve in both control directions goes from 4 to 11 bar [from 58 to 159 PSI] (tollerance ± 5%). The adjustment
curve of the hydraulic control system has to be wider (from 4 to 15 bar [from 58 to 217 PSI]).
