General Information
Introduction
Parker’s P2 / P3 series has been designed to meet the
specific demands of heavy duty mobile applications
throughout the following markets:
– Material Handling Equipment (e.g Reachstacker,
HD Lift Trucks, AT Cranes)
– Construction Equipment (e.g. Articulated Dump
Trucks, Wheel Loaders)
– Mining and Drilling (e.g. Dump Trucks, Drill Rigs)
– Forestry Equipment (e.g. Forwarder, Harvester)
By featuring an optimized envelope and a unique port
layout the product line provides for a cost saving direct
mount on most typical mobile transmissions. High
speed ratings enable high flow and productivity levels.
With continuous pressure ratings of up to 350 bar
P2 / P3 provides a high power density and enables
downsizing of mobile machinery. As a standard every
P2 / P3 comes with an integrated pre-compression
volume which ensures low ripple operation and reduced
noise emissions.
After having proven in load-sensing systems for many
years Parker’s series P2 / P3 is now extended by a
new electronic control concept (eP2 / eP3), setting new
standards in responsiveness, stability and efficiency.

Axial Piston Pumps
Series eP2/eP3 - Electronic Controls
Electronic Control Options
Electronic Displacement Controls EC and EF
Electronically displacement controlled eP2 / eP3
provides an output flow defined by a displacement input
command and maintains its swash angle (and thereby
output flow level) until a new displacement command is
received.
Under static displacement control conditions - i.e.
as long as actual pump displacement (actual value)
corresponds to displacement command (nominal
value) - the control spool of the pump‘s control valve is
held at metering edge (zero point). This is realized by
applying a defined holding current (PWM signal) to the
valve‘s proportional solenoid. If commanded displace-
ment changes (actual value ≠ nominal value) the
control spool is moved from its zero point. Depending
on specified default setting (EC: 0% displacement / EF:
100% displacement) raising the current either results in
an increased (EC) or decreased (EF) displacement of
the pump. As soon as desired displacement has been
achieved (actual value = nominal value) the control
spool returns to its zero point.
Default options (behaviour at power loss):
EC 0% (zero displacement)
EF 100% (maximum displacement)
A minimum servo pressure of 15 bar is required to
control the pump. Without adequate servo pressure
the pump is mechanically biased on stroke. If a system
pressure of below 15 bar is required the pump might be
equipped with a preload valve. Please consult Parker
for further information.
Closed control loop
By featuring both an electro-proportional directional
control valve and a swash angle sensor the eP2 / eP3
design takes advantage of a closed control loop which
provides for:
• Increasedaccuracyandsystemresponse
• Higherstabilityandminimizedoscillation
• Improvedfuelefciency
• Electronicdisplacementfeedbackforanalysisand
sub-system communication
Closed loop working principle:
Power savings
Compared to a conventional hydro-mechanical
compensator based approach the electronic displace-
ment control of eP2 / eP3 is characterized by a
significantly reduced compensator oil consumption and
thereby increased volumetric efficiency. Thus eP2 / eP3
provides for considerable power savings (measured
values at 1500 rpm):
Fuel saving potentials
Beside providing for improved control characteristics as
well as power savings by control design eP2 / eP3 also
enables new hydraulic system approaches such as the
purely electronic control of single actuator operation,
which eliminates the delta p losses of a conventional
LS system.
Example:
∆p = 20 bar
Q = 150 L/min (75 cc/rev @ 2.000 rpm)
Resulting power consumption = 5 kW
Potential fuel saving @ 1.500 h/a and 0,2 l/kWh:

Control Functions and Options
As an option eP2 / eP3 can be equipped with a pres-
sure sensor to either grant for pressure monitoring or to
realize electronic pressure limitation. Pressure limitation
function as well as secondary control options such as
variable input torque limitation and speed compen-
sation / flow control require the usage of a Parker
supplied Pump Control Module (PCM). PCM command
inputscanbebothanalog(0..5V)orCAN(J1939).
The following chart shows the range of available control
functions (eff. March, 2018):
Note:
The hydraulic circuit must be equipped with a main
flow relief valve to secure pump and hydraulic
components. This main flow relief valve is outside
the scope of supply.

General Installation Information
Recommended hydraulic fluids
Hydraulic fluids based on mineral oils acc. to
DIN51524,part2and3(HLP/HVLP).
Pumps of series P2 / P3 can also be operated with
environmentally acceptable (bio-degradable) and
synthetic hydraulic fluids. Please consult Parker for
further details.
Please check the specification of selected hydraulic
fluid for chemical resistance with the pump’s sealing
material (shaft seal, O-rings).
Hydraulic fluid cleanliness level
For maximum component life and reliability a cleanli-
ness level of 18/16/13 (acc. to ISO 4406) is recom-
mended for eP2 / eP3.
Viscosity
Minimum viscosity for short periods:
10mm²/s (cSt)
Recommended continuous operating viscosity:
[15…40] mm²/s (cSt)
Maximum cold start viscosity:
1000 mm²/s (cSt)
Temperature
Check temperature range of selected seal material and
compare with maximum system and ambient tempera-
ture.
The following limitations refer to average case drain
temperature (measured at drain port), which can be up
to 20 °C higher than in the reservoir:
Sealing option Tmin [°C] Tmax [°C]
N / D -25 +80
B / Q -40 +80
V/T -25 +80
Shaft Loads
Please strictly follow the instructions of the coupling /
PTO supplier regarding axial clearance, axial alignment
and angular tolerances. The drive shaft should only
carry torque. Units subjected to radial loads require the
installation of an outboard bearing. Axial loads are not
permitted.
