Operational parameters. Life time recommendations
Operational parameters. Filtration
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 according to Linde Works Standard WN 51 210. High purity oil can extend the service time of
the hydraulic system significantly.
Beneficial conditions for long service life
>> Speed lower continuous maximum speed
>> Operating pressure less than 300 bar ∆p on average
>> Max. pressure only at reduced displacement
>> Viscosity 15 ... 30 cSt
>> Power continuous power or lower
>> Purity of fluid 18/16/13 in ac. 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 ∆p on average
>> Viscosity less than 10 cSt
>> Power continuous operation close to max. power
>> Purity of fluid lower than 18/16/13 in acc. with ISO 4406
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.
>> 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 hydrau-
lic 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
Filters
Units of the HPV-02 series can be equipped with a pure charge pressure manifold or with a combined charge pressure and filter
flange manifold. The following filter sizes are available, depending on the rated size of the unit. Further details about the mounting
of the charge pressure manifold see section "Dimensions. Modular System".

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 is 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
temperature is always higher than the circuit temperature. Please contact Linde if the stated conditions cannot be met in special
circumstances.

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 51 524-2
>> biodegradable fluids in accordance with ISO 15 380 on request

Gear pumps.
Two types of gear pumps are available: internal gear pump IGP and external gear pump EGP. The possible combinations of and
with IGP and EGP are determined by the PTO option and the permitted shaft torque. Both types can be used as charge pump for
the main circuit or the control and cooling circuit. The allowable pressure at the suction port is between 0.8 bar (abs.) and 3.0 bar
(abs.). The charge pressure relief valves for the rated sizes 55-135 are integrated in the port plate housing, and for the rated sizes
165-280 in the charge pressure manifold of the HPV-02.

Controls.
The modular control concept with standardised interface enables quick selection and adaptation for different customer and sys-
tem requirements with mechanical, hydraulic or electronic control. All Series 02-controls feature an upstream signal circuit that
is adapted to the respective control, and a standardised and load-independent servo control for simple and constantly available
machine or vehicle control.

Displacement relative to pilot pressure and pressure cut-off regulation for H- and E-controls
Special control elements deal with functions such as torque control or pressure cut-off regulation. Controls with pressure cut-off
regulation (PCO) reduce pump flow when the cut-off pressure is reached. Because system pressure is maintained at low flow, the
power consumption and thermal balance of the system are optimised.

fixed, variable or regulating motor or a variable motor with pressure regulator. The modular design offers a high degree of versa-
tility in terms of function and control.

Controls. Electro-hydraulic E1 and E5
The HPV-02 E1 has two proportional solenoids and through the upstream signal circuit it combines the flexibility of electronic vehi-
cle management with the reliability of a pump control marked by its high operational availability. Precise and simple. Identical com-
mands always call for the same response in the machine, so no corrective action is required by the operator or the electronic system.
The HPV-02 E5 has two switching solenoids and thus sets the pump to either neutral or maximum swash angle of any direction.

Controls. Electro-hydraulic E2
The HPV-02 E2, with its additional release function, can easily be integrated in an electronic vehicle management control system
like an E1-control. In addition it offers a safety standard that meets the stringent requirements for road traffic use. The E2-control
features two proportional solenoids and a switching solenoid.
E2 with switch-off function
The E2 control offers an interface for switching off the whole
system. In case of signal irregularity or perturbation like cable
break or short-circuit in the switching solenoid circuit (co called
'watchdog'), the pump swashes back to neutral position in a
defined manner.
The vehicle is decelerated until standstill and thus provides a
safe condition of the machine as per EN ISO 13849.
In case of disfunction in the proportional magnets' circuits, a
similar reaction can be induced by the intervention of the elec-
tronic control units.
Its use is recommended for mobile applications where specific
safety criteria have to be met in terms of travel and coasting
behaviour, e.g. road traffic use.

Verstellungen. Elektro-hydraulisch E2
Die HPV-02 E2 ist mit ihrer zusätzlichen Freigabefunktion ebenso einfach in ein elektronisches Fahrzeugmanagement integrierbar
wie mit einer E1-Verstellung. Darüber hinaus bietet sie den für eine Straßenzulassung erforderlichen hohen Sicherheitsstandard. Die
E2-Verstellung hat zur Ansteuerung zwei Regelmagnete und einen Schaltmagneten.
E2. Elektro-hydraulische Verstellung
E2 mit Sicherheitsfunktion
Die elektronische Steuereinheit vergleicht den Fahrbefehl mit
anderen Maschinensignalen. Bei Abweichung (z.B. bei
Stromausfall durch Kabelbruch oder Kurzschluss) deaktiviert die
elektronische Steuereinheit den Freigabemagneten an der
E2-Verstellung und die Pumpe wird aktiv und kontrolliert zurück-
geschwenkt. Dadurch wird das Fahrzeug gezielt bis zum
Maschinenstillstand gebremst – ohne den Fahrer zu gefährden.
Der Einsatz empfiehlt sich bei Fahrantrieben mit besonderen
Sicherheitsanforderungen hinsichtlich des Fahr- und Ausrollver-
haltens, z.B. bei Straßenfahrt.
Produktvorteile E2
>> entspricht den hohen Anforderungen der Strassenzulassung
>> aktive Fahrtfreigabe
>> minimierte Störanfälligkeit

Dimensions. HPV-HPR-02 multiple pumps
Multiple pumps are created by combining individual pump units in series, with the pumps arranged by capacity. Positioning the
gear pump(s) at the end of the unit ensures optimum space utilization, output allocation and load distribution. The following table
is based on the gear pump acting as charge pump for the HPV-02 variable pump.
