Control Option “C”
Pressure Limiter
Adjustment Range = 26-280 bar (380-4060 psi)
The "C0" pressure limiter control is used to limit the maximum
system pressure. The control acts such that full pump
displacement is achieved unless the system valve restricts
the output flow or the load pressure reaches the maximum
setting of the control. If pump flow is restricted by the system
valve, the pump will provide only the flow demanded, but at
the maximum pressure setting of the compensator control. If
the outlet flow is completely blocked, the pump will destroke
to zero displacement and maintain the pressure at the setting
of the compensator spring.

Pressure Limiter Adjustment Range =
26-280 bar (380-4060 psi)
Dierential Adjustment Range = 10-40 bar (150-580 psi)
The "L0" and "L2" controls feature load sensing and
maximum pressure compensation. A load sense line that
comes from downstream of the main system throttling valve
is connected to the "X" port on the control. This control
matches pump flow and pressure to system demands by
maintaining a constant pressure drop across the main
system throttling valve, thus reducing horsepower losses.
The pump automatically adjusts for changes in drive speed
and load pressures. Choose the "L2" option if bleeding the
load sense line at the pump is desired.

The "AM" control allows the pump pressure compensator
setting to be adjusted from a remote relief valve that is

such that full pump displacement is achieved unless the
system valve restricts the output flow or the load pressure
reaches the maximum setting of the control. If pump flow is

* Based on NFPA testing standards
The "AN" control is a standard pressure compensator, but
with a NG6 ( D03) valve interface. It is the same as the
"AM" control, but with the addition of an adapter block
mounted between the pump housing and control to provide
the NG6 (D03) interface. This allows a directional valve or
proportional relief valve to be mounted directly on the pump
to achieve a variety of pressure control circuits.
Caution: Pumps shipped with the “AN” control need to have
a valve mounted to the NG6 interface for operation. This is
not a functional control as shipped.

CONTROLS INFORMATION CONTROLS INFORMATION
Control Options “AMT,” “ANT,” and “L0T”
Torque Limiting Controls: (45-140cc only)
AMT = Remote pressure limiting with torque limiting
ANT = Pilot operated pressure limiting with torque limiting
L0T = Load sense & pressure limiting with torque limiting
These controls provide the benefit of pressure limiting
control, plus the ability to limit the input torque when the
power available from the prime mover is limited; or when the
application power demand has both high flow/low pressure
and low flow/high pressure operating conditions.
“AMT” & "ANT" Control
The "AMT" and "ANT" combine the pilot pressure limiter
function with a torque limiting function. On the "AMT"
control, the pressure limiter function is controlled remotely
by connecting an external relief valve to the "X" port. On the
"ANT" control, the pilot relief valve is mounted directly on the
pump via the NG6 interface on the control block. Once the
torque limiter setting is reached, the pump will destroke as
pressure continues to rise in order to maintain the same input
torque. Once the pressure limiter setting is reached, the pump
will destroke to limit the system pressure.
Caution: The ANT control will not function without a
valve mounted on the NG6 interface.

"L0T" Control
The "L0T" combines the functions of a pressure limiter, load
sense and torque limiter control. The pressure limiter function
limits the maximum pump outlet pressure. The load sense
control function requires the "X" port to be connected to the
highest load pressure via a load sense signal line. The control
will match pump output flow and pressure to the system
demand , thus minimizing horsepower losses. The pump will
operate in a load sense mode until the torque limiter setting
is reached, and then the pump will maintain the input torque
at the pre-selected setting. If the system pressure reaches
the pressure compensator setting, then the pump flow will
be lowered to the level needed to maintain the maximum
pressure setting.

Control Options “P,” “T,” “S,” “U”
Electronic Proportional Displacement & Pressure Limiting
P = Min displacement default*
T = Max displacement default*
S = Min displacement default and hydromechanical pressure limiter
U = Max displacement default and hydromechanical pressure limiter
* Pumps without pressure limiter should be designed in a circuit with other means of pressure limitation.
The control uses the D1FB electronic proportional valve
from Parker's Hydraulic Valve Division to provide the precise
flow specified per a displacement input command and
maintain that flow level until a new displacement command
level is received, or until the pressure command overrides
to limit system pressure.
The holding current can vary from pump to pump, but is
typically between 1.3-1.6 Amps for the 12V valve and
650-800 mA for the 24V valve.
A minimum of 25 bar servo pressure is required to control
the pump. To control the pump at system pressure below
25 bar, either a sequence valve in the pressure line or an
external servo source is required. Without adequate servo
pressure, the pump is biased on stroke.
The mechanical pressure limiter will override the electronic
inputs and limit pump outlet pressure to the preset level.
Using electronic control, the pump can be used in
overcenter condition. (Energy recovery is one example
of application for this.)

Shaft Information
These pumps are designed to operate with the shaft horizontal or pointing downward.
For shaft up mounting consult factory. The pump shaft must be in alignment with the shaft
of the source driver and should be checked with a dial indicator. The mating pilot bore and
coupling must be concentric. This concentricity is particularly important if the shaft is rigidly
connected to the driven load without a flexible coupling.
Splined: The shafts will accept a maximum misalignment of 0.15mm, 0.005 inch, total
indicator reading. Angular misalignment at the external and internal spline axis must be
less than ± 0,002 mm per mm of shaft radius, ± 0.002 inches per inch of shaft radius.
The coupling interface must be lubricated. PARKER recommends lithium molydisulfide or
similar grease. The internal coupling should be hardened to Rc 27-34 and must conform to
SAE-J498c, class 5 flat root side fit.
Keyed: High strength heat treated keys must be used. Replacement keys must be hardened
to 27-34 Rc. The key corners must be chamfered 0.81-1.0 mm, 0.032”-0.040”, at 45° to
clear radii that exist in the keyway.
The P1/PD series is designed for inline-drive. Side loading on the shaft is not
recommended. If this is unavoidable consult your nearest PARKER representative.
Connect inlet and outlet lines to the port block of the pump. The maximum case pressure is
2 bar (30 psi) continuous, 4 bar (60 psi) intermittent. The case pressure must never exceed
inlet pressure by more than .5 bar (7 psi). When connecting case drain line make certain
that drain plumbing passes above highest point of the pump before passing to the reservoir.
The case leakage line must be of sucient size to prevent back pressure in excess of 2
bar(30 psi) and returned to the reservoir below the surface of the oil as far from the supply
inlet as possible. All fluid lines, whether pipe, tubing, or hose must be adequate size and
strength to assure free flow through the pump. An undersize inlet line will prevent the pump
from operating properly at full rated speed. An undersize outlet line will cause back pressure
and cause heat generation and increased noise. Flexible hose lines are recommended. If
rigid piping is used, the workmanship must be accurate to eliminate strain on the pump port
block or to the fluid connections. Sharp bends in the lines must be eliminated wherever
possible. All system piping must be cleaned and flushed before installing pump. Make sure
the entire hydraulic system is free of dirt, lint, scale, or other foreign material.
CAUTION: Do not use galvanized pipe. Galvanized coating can flake o with continued use.
Although the P1/PD series pumps have very fast o-stroke compensator response, system
relief valves are recommended in all cases for safety considerations.
The fluid recommended for use in these pumps has a petroleum base and contains agents
which provide oxidation inhibition and anti-rust, anti-foam and de-aerating properties as
described in PARKER standard HF-1. Where anti-wear additive fluids are specified, see
PARKER standard HF-0.
90 V. I. minimum. Higher values extend the range of operating temperature but may reduce
the service life of the fluid.
Determined by the viscosity characteristics of the fluid used. Because high temperatures
degrade seals, reduce the service life of the fluid and create hazards, fluid temperature
should not exceed 110°C (230°F) at the case drain.
The pump is self-lubricating and preventative maintenance is limited to keeping system
fluid clean by changing filters frequently. Keep all fittings and screws tight. Do not operate
at pressures and speeds in excess of the recommended limit. If the pump does not
operate properly, check the troubleshooting chart before attempting to overhaul the unit.
Overhauling may be accomplished by referring to the disassembly, rework limits of wear
parts, and assembly procedures as provided in this service manual.
Fluid must be cleaned before and continuously during operation, by filters that maintain a
cleanliness level of ISO 20/18/14. Better cleanliness levels will significantly extend the life
of the components. As contaminant generation may vary with each application, each must
be analyzed to determine proper filtration to maintain the required cleanliness level.

dress and trade secrets (“Intellectual Property Rights”). Seller will defend at its expense
and will pay the cost of any settlement or damages awarded in an action brought against
Buyer based on an allegation that a Product sold pursuant to this Agreement infringes the
Intellectual Property Rights of a third party. Seller’s obligation to defend and indemnify
Buyer is contingent on Buyer notifying Seller within ten (10) days after Buyer becomes
aware of such allegations of infringement, and Seller having sole control over the defense
of any allegations or actions including all negotiations for settlement or compromise. If
a Product is subject to a claim that it infringes the Intellectual Property Rights of a third
party, Seller may, at its sole expense and option, procure for Buyer the right to continue
using the Product, replace or modify the Product so as to make it noninfringing, or oer to
accept return of the Product and return the purchase price less a reasonable allowance
for depreciation. Notwithstanding the foregoing, Seller shall have no liability for claims of
infringement based on information provided by Buyer, or directed to Products delivered
hereunder for which the designs are specified in whole or part by Buyer, or infringements
resulting from the modification, combination or use in a system of any Product sold
hereunder. The foregoing provisions of this Section shall constitute Seller’s sole and
