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.
8
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 control of actuators
>> Dynamic response characteristics
>> Load-independent, synchronous movements of
several actuators

>> 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

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.

Zahnradpumpen.
Die Zahnradpumpen sind in zwei Bauarten verfügbar: Innenzahnradpumpen IZP und Außenzahnradpumpen AZP. Die möglichen
Kombinationen von und mit IZP und AZP werden durch die PTO-Option und das zulässige Wellendrehmoment bestimmt. Beide Bauarten
können für den Steuer- und Kühlkreislauf eingesetzt werden. Dabei ist die Sauggrenze von mindestens 0,8 bar (absolut) einzuhalten.

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>>).
