**) theoretical data of a single unit without efficiency effects
The maximum input and maximum PTO torque allows to form multiple units. One of the first two pumps in such an assembly can thereby operate at maximum power,
while the other can operate at continuous power. The PTO at the second pump then offers 30% of a single pump's continuous power rating. Example for HPR 135-02:
Maximum input torque = 907 Nm + 540 Nm + 540*0.3 Nm = 1609 Nm

Operational parameters. Life time recommendations
Life time recommendations
Linde high pressure units are designed for excellent reliability and long service life. The actual service life of a hydraulic unit is
determined by numerous factors. It can be extended significantly through proper maintenance of the hydraulic system and by using
high-quality hydraulic fluid.
Beneficial conditions for long service life
>> Speed lower continuous maximum speed
>> Operating pressure less than 300 bar Δp on average
>> Max. pressure only at reduced displacement
>> Viscosity 15 ... 30 cSt
>> Power continuous power or lower
>> Purity of fluid 18/16/13 in accordance with ISO 4406 or better
Adverse factors affecting service life
>> Speed between continuous maximum speed and
intermittent maximum speed
>> Operating pressure more than 300 bar Δp on average
>> Viscosity less than 10 cSt
>> Power continuous operation close to maximum power
>> Purity of fluid lower than 18/16/13 in accordance with ISO 4406
7
Operational parameters. Tank connection, filtration, mounting orientation
Tank connection
The leakage and decompression oil generated during pump operation is drained from the rotating group into the pump housing.
Excessive housing pressure must be avoided through suitably dimensioned piping between the housing and the tank.
Filtration
High purity oil can extend the service time of the hydraulic system significantly. In order to guarantee long-term proper function
and high efficiency of the hydraulic pumps the purity of the pressure fluid must comply with the following criteria.
>> For reliable proper function
and long service life
18/16/13 in accordance with ISO 4406 or better
>> Minimum requirements 20/18/15 in accordance with ISO 4406
>> Commissioning The minimum purity requirement for the hydraulic oil is based on the most sensitive system
component. For commissioning we recommend a filtration in order to achieve the required
purity.
>> Filling and operation
of hydraulic systems
The required purity of the hydraulic oil must be ensured during filling or topping up.
When drums, canisters or large-capacity tanks are used the oil generally has to be
filtered. We recommend the implementation of suitable measures (e.g. filters) to
ensure that the required minimum purity of the oil is also achieved during operation.
>> International standard code number according to ISO 4406 purity class according to SAE AS 4059
18/16/13 corresponds to 8A/7B/7C
20/18/15 9A/8B/8C
Mounting orientation
The preferred mounting orientation is generally horizontal. Pump configurations for vertical mounting with the shaft pointing
upwards have an additional drain port "R" at the mounting flange. These units are available with certain combinations of features
and have to be requested separately.
For further information concerning the installation of the unit please refer to the operating instructions manual.
In order to be able to select the right hydraulic fluid it is necessary to know the working temperature in the hydraulic circuit. The
hydraulic fluid should be selected such that its optimum viscosity is within the working temperature range (see tables).
The temperature should not exceed 90 °C in any part of the system. Due to pressure and speed influences the leakage fluid tem-
perature is always higher than the circuit temperature. Please contact Linde if the stated conditions cannot be met or in special
circumstances.

Operational parameters. Pressure fluids
In order to ensure the functional performance and high efficiency of the hydraulic pumps the viscosity and purity of the operating
fluid should meet the different operational requirements. Linde recommends using only hydraulic fluids which are confirmed by
the manufacturer as suitable for use in high pressure hydraulic installations or approved by the original equipment manufacturer.
Permitted pressure fluids
>> Mineral oil HLP to DIN 51524-2
>> Biodegradable fluids in accordance with ISO 15380 on request
>> Other pressure fluids on request

Linde LSC-System.
The Linde Synchron Control System (LSC-System) for open loop hydraulic circuits enables demand-orientated pump volume control
based on load sensing technology (LS technology). A LSC-System compensates the effect of varying loads, varying numbers of
actuators and different load levels at different actuators. This happens automatically, thereby making machine operation more
convenient since, unlike in other systems, continuous corrective action is no longer required. The LSC-System enables high-effi-
ciency hydraulic systems to be realized that are strictly orientated to the machine functions. Our application specialists will be
happy to provide advice for individual machine configurations.
Functionality
>> Demand-oriented pump control
>> Excellent precision control characteristics without readjust-
ment
>> Exact reproducibility of machine movements through
exact control of actuators
>> Dynamic response characteristics
>> Load-independent, synchronous movements of
several actuators
>> "Social" oil distribution even in the event of overload
>> Automatic venting of directional control valve end caps
>> Optimum movement continuity even for combined
movements
Further optional functions such as
>> Priority control of individual actuators
>> Output control
>> High-pressure protection
>> Regeneration function
>> Combined function shuttle valve
>> Load holding function
Machine equipment
>> Customized system design for optimum implementation
of customer requirements
>> Optimum utilization of the installed power with
simultaneous improvement of energy consumption
>> High flexibility through manifold plates
>> Compact, integrated solutions
>> Modular design of valve sections
>> Add-on cylinder valves for direct and fast cylinder
supply, no additional hose burst protection required

Noise reduction. SPU silencer
In hydraulic systems pressure pulsations can lead to noise emission. These pressure pulsations are a result of the inherent non-
uniformity of the volume flow in rotary piston pumps. In open loop hydraulic circuits pressure pulsations primarily originate from
within the hydraulic pump during the compression stroke, i.e. when a piston coming from the low-pressure side (suction side)
enters the high-pressure side, where it is suddenly subjected to high pressure. The higher the pump speed and the pressure dif-
ference between the low-pressure and high-pressure side, the more pulsation energy is added to the hydraulic system via the
hydraulic fluid. Pressure pulsations can cause components of the hydraulic system or the machine to oscillate, thereby generating
noise that is perceivable for the human ear.
All Linde hydraulic pumps are optimized with respect to pulsation characteristics and therefore noise generation. In addition to
common primary measures such as exclusive use of pulsation-optimized port plates, Linde Hydraulics offers the SPU silencer for
HPR-02 open loop pumps. Without affecting the functionality and efficiency of the pump, this system reduces pressure pulsations
by up to 70 %, irrespective of pressure, speed or temperature. The SPU system is adaptive over the entire operating range. No
setting up or maintenance is required.

In principle noise emissions from machinery with hydraulic
systems can be reduced in the following ways:
>> Reduction of operating pressure and speed. This reduces the
pulsation energy introduced into the hydraulic system
>> Primary measures for optimizing the compression stroke in
rotary piston machines with the aim of reducing pulsation
>> Secondary measures such as vibration-optimized design and
installation of machine components and sound-proofing for
noise suppression

Gear pumps.
External gear pump EGP
Overview gear pumps
The gear pumps are available in two designs. Internal gear pumps (IGP) and external gear pumps (EGP). Both types can be used
for the control circuits as well as the cooling circuit. The suction is always external for both types, when used in combination with
a HPR-02. The internal connection of the IGP is closed.
Internal gear pumps offer a cold start valve and a PTO interface for mounting further pumps. The possible combinations of IGPs and
EGPs are determined by PTO option and the permitted shaft torque.

Controllers.
The modular controller unit enables a wide range of functional system requirements to be met. In all controller unit versions, the
regulating functions are integrated in a housing in order to ensure direct signal transfer without delays and with maximum com-
pactness. All controllers equipped with load sensing function are fully compatible with the Linde Synchron Control System (see
section <<Linde LSC-System>>).

Controllers. LS. Load Sensing
LS-function at ∆p = constant
Linde pumps with load sensing control enable the movement speed required of the selected actuator, e.g. of a boom, to be spe-
cified via the valve opening. The measured pump and load pressures are continuously balanced by the load sensing controller of
the hydraulic pump.
Benefits of LS-control
>> Any volume flow below the pump`s maximum can be set
>> Response speed of the machine can be defined
>> OEM-specific machine response is possible
>> Optimum precision control capability
Volume flow
A
Volume flow
∆p
A pressure gradient is set at the controller, which is defined by the actuator requirements. The volume flow results from the orifice A
of the control valve and the actual pressure gradient. Due to the LS-controller, the ∆p corresponds to the setting value. If the requi-
red volume flow differs, the pump displacement is changed accordingly. This happens automatically and reduces the effort required
by the operator. Since varying loads and varying numbers of actuators are compensated automatically. The ∆p LS basic setting is
possible from 16 to 27 bar with 20 bar as standard (the LS differential pressure influences the response times of the pump system).
LS-function at area A = constant
Demand-oriented pump control offers the
following benefits
>> Load-independent machine control
>> Minimum heat generation
>> Increased pump service life
>> Low noise generation in the whole system
>> Fewer components for the control mechanism
>> Lower energy consumption, particularly with partial volume

In addition to the load sensing function the LP-controller offers maximum pressure limitation. Once the system pressure reaches
the set pressure of the pressure cut-off valve, the LS-controller is overridden and the pump swashes back, whilst maintaining the
system’s regulating pressure. The hydraulic pump remains in this state until the system pressure falls below the set pressure. The
hydraulic pump then returns to normal LS operation.

The maximum pressure cut-off valve prevents prolonged operation of pressure relief valves installed in the hydraulic system for
protection. This has the following benefits for the hydraulic system:
>> Operating pressure is maintained
>> No operation in the overload range
>> Any operating point under the power
curve remains accessible
>> Demand-oriented volume flow generation
>> Minimum power loss
>> Reduced heat and noise generation
>> Longer service life of the pump and the
entire hydraulic system
>> Improved energy consumption of the overall system

Possible applications of the LS signal override
Controllers. E1L/H1L. Load Sensing with electric / hydraulic override
>> Mode-control
A mode control (mode selection) modulates electrically the ∆p LS-signal at an orifice (e.g. directional control valve). The current
∆p LS value is reduced proportionally or in steps and the pump output adjusted via the pressure reducing valve (see the diagrams
on following pages.) In this way the volume flow of the pump can be reduced using the same orifice. In applications with propor-
tional valves this leads to enhanced control resolution, enabling particularly precise and sensitive actuator movement.
>> Power limit regulation
Any reduction in the prime mover speed is detected in conjunction with an electronic control unit, and the pump's volume flow is
limited through modulation of the ∆p LS value to ensure that the maximum power capacity is not exceeded. The maximum prime
mover power is thus available at all times, irrespective of ambient influences and the number of actuators.
In principle, the ∆p LS value acting at the LS-pilot can be modulated down to zero, whereas modified response times of the pump
system should be expected in the operating range near zero.
In addition to the load sensing function, HPR-02 pumps with H1L or E1L controllers offer the possibility of overriding the ∆p
LS-signal hydraulically or electrically. This enables a so called mode control for selecting different operating points or enables a
power limit regulation (underspeed control). The integration of all functions in the pump controller enables direct signal transfer
without delay. The controller-specific data are independent of the nominal pump size.

In addition to the load sensing function, the HPR-02 E1L offers an electric override for mode selection and power limit regulation
(underspeed control). The integration of all functions in the pump controller enables direct signal transfer without delays. The
controller-specific data are independent of the nominal pump size.
Controllers. E1L. Load Sensing with electric override
∆p LS-reduction
In the event of an electric override of the LS-signal, a pressure reducing valve is activated via the proportional solenoid. The
control pressure generated in this way acts proportionally against the LS-spring, and the effect of the ∆p LS signal is modulated
accordingly. This causes the pump to swash back, thereby reducing its output. The function between control current (l) at the
control solenoid and the associated ∆p LS value is shown in the diagram. At the port "A", the control pressure can be picked up and
forwarded to an H1L controller at another HPR pump, which follows the first pump with the E1L controller (master-slave-operation).
In case of a malfunction in the electric control, a control pressure can be fed to the E1L controller at the port "X1" to reduce the
∆p LS setting and therefore keep the application operational.

In addition to the load sensing function, HPR-02 pumps with H1L-controller offer the possibility of overriding the ∆p LS-signal
hydraulically. This enables either a so called mode control for selecting different operation points or establish a power limit regula-
tion (underspeed control). The integration of all functions in the pump controller enables direct signal transfer without delay. The
controller-specific data are independent of the nominal pump size. The H1L-controller is particularly useful for tandem configura-
tions of two HPR-02 pumps, in which the first is equipped with an E1L-controller. The second pump with H1L-controller uses the
resulting hydraulic signal of the first controller and follows the first pump’s actions (master-slave-configuration).
In the event of hydraulically overriding the LS-signal, a control pressure is applied to the port “A” of the controller. This pressure
acts proportionally against the LS-spring, and the LS signal is modulated accordingly. This causes the pump to swash back, thereby
reducing its output. The function between control pressure at the port A and the associated ∆p LS value is shown in the following
diagram.

Pump controllers with position feedback
TL2-, LEP- and ETP-controllers offer a feedback of the swashplate position. Therefore they are – unlike LP-, E1L- and H1L-controllers
– not mounted on the valve plate housing, but on the pump housing. Besides their individual characteristics, these controllers have
some similar features.

The swash angle and thus the flow of the pump is set by means of an electric signal with the LEP and ETP controller. The actual
current depends on the voltage-level of the application and the nominal size of the pump.
Without an electric signal, the pump swashes to minimal displacement.
LEP- and ETP-controllers offer a pressure cut-off (PCO), just like the LP-controller. This prevents the pump pressure exceeding a
previously set maximum. The PCO is set to a customer-specific value between 125 bar and 420 bar ex works. Using a control signal
at the XD port, the actual response pressure of the PCO valve of LEP- and ETP-controllers can be increased steplessly. The response
pressure of the valve is increased by 4.3 bar by every bar increase at the XD port. The maximum pressure of 420 bar must not be
exceeded.

Controllers of the TL2 and ETP type offer a power limitation with a hyperbolical characteristic. The controller is set ex works to a
customer specific power limit value. The volume flow is restricted, when this limit is exceeded. By means of control ports at the
controller, the point at which the power limiter sets in can be raised, as well as lowered during operation.
Dependent on the rated size of the unit, there is a minimum value for the power limitation which must not be underrun, neither
by the ex work setting, nor by shifting. The maximum mechanically set value at which the power limitation sets in, is 250 bar,
independent of the pump's rated size and speed. The pump must never be operated with more than its maximum power.

The control principle with power limitation is used to optimize power utilization of the prime mover in applications where less
than the full power capacity is available for the hydraulic system. In addition to the load sensing function the HPR-02 TL2 offers
hyperbolic power limitation. The volume flow is limited when the set value is reached.

The TL2 controller offers a so called hydraulic power mode function. This means, that the regulation begin of the power limitation
/ torque control can be shifted from its mechanical basic setting by means of a remote control port Z1/Z2 at the controller. If the
regulation begin is intended to be below the basic setting, which means that the pump performance is reduced, then the port Z2
is used while S4 is closed. If the mode function is not used at all, or only with the Z1 port, S4 is equipped with an orifice. Z2 is then
sealed pressure tight. For details, see <<Pump controllers with position feedback. T-axis>>

Controllers. LEP. Load Sensing with electro-proportional flow limitation
and pressure cut-off
Characteristic LEP controller LEP-controller
Without any signal at the solenoid or the LS-port, the pump is swashed back to stand-by position. Both signals at the same time
are required for the pump to leave stand-by position. The actual swash angle of the pump is determined by the signal with the
lower target value.
The responding behaviour of the pressure cut-off can be remote-controlled by a hydraulic signal at the XD port as an option. S1 is
then equipped with an orifice and S2 is sealed. If only the mechanical preset of the PCO is used, S1 is sealed and S2 is not equipped.
Details, see <<Pump controllers with position feedback. P-axis>>
The HPR with LEP-controller offers an on-demand load sensing flow control. The actual volume flow, delivered by the pump can
be restricted by an electrical signal in certain points of operation. A pressure cut-off function protects the hydraulic system from
overload.

Controllers. ETP. Electro-proportional flow setting, power limitation
and pressure cut-off
The HPR with ETP-controller delivers a volume flow which is exactly proportional to the electric control signal. Superposed, the
controller offers a hyperbolic power limitation, which optimally exploits the power of the prime mover and also protects it from
overload. In addition to this, a pressure cut-off protects the hydraulic system.
The controller is supplied via a feed port "E" at the port plate housing.
The ETP-controller offers a so called hydraulic power mode function. This means, that the regulation begin of the power limitation
can be shifted from its mechanical basic setting by means of a remote control port Z1/Z2 at the controller. If the regulation begin
is intended to be below the basic setting, which means that the pump performance is reduced, then the port Z2 is used, S4 is
closed. If the mode function is not used at all, or only with the Z1 port, S4 is equipped with an orifice. Z2 is then sealed pressure
tight. For details, see <<Pump controllers with position feedback. T-axis>>
The responding behaviour of the pressure cut-off can be remote-controlled by an hydraulic signal at the XD port as an option.
S1 is then equipped with an orifice and S2 is sealed. If only the mechanical preset of the PCO is used, S1 is sealed and S2 is not
equipped. Details, see <<Pump controllers with position feedback. P-axis>>

Dimensions. Double pumps and plug-in pumps
Double pump with SAE J744 flange Double pump with SAE J617a flange
Double pumps consist of two HPR rotating groups, arranged back-to-back to a common port plate housing, sharing one common
suction port. They are thus more compact than two standard pumps in a tandem configuration. Compared to a pump of equal rated
size with a single rotating group, double pumps offer higher speed and more narrow radial dimensions. They also provide a PTO
option. The position of the ports, controllers and SPU differs from the previously shown pumps.
