Operational Parameters
Life Time Recommendations, Filtration and Filters
Filtration
Filters
In order to guarantee long-term proper function and high efficiency of the hydraulic pumps
the cleanliness level of the lubricant must comply with the following criteria according
to Eaton Hydraulic Fluid Recommendation 03-401-2010. Maintaining the recommended
cleanliness level can extend the service life of the hydraulic system significantly.
Beneficial Conditions For Long Service Life
Speed Lower continuous maximum speed
Operating Pressure Less than 300 bar 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
Eaton 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.

No. 2 x
No. 3 x x x x x x x
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.
Adverse Factors Affecting Service Life
Speed Between continuous maximum speed and
intermittent maximum speed
Operating Pressure More than 300 bar 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
Units of the HPV 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 avail-
able, depending on the rated size of the unit. Further details about the mounting of the
charge pressure manifold see section "Dimensions. Modular System".

Operational Parameters
Pressure Fluids, Mounting Orientation
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 Eaton
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.
Eaton 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.

The preferred mounting orientation is generally horizontal. Special pump configurations
for vertical mounting with the drive shaft pointing either upward or downward are avail-
able for selected rated sizes and have to be requested separately.
For further information concerning the installation of the unit please refer to the operat-
ing instructions manual.

Gear Pumps
External gear pump EGP
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 boost pump for the main circuit or
the control and cooling circuit. The suction limit of 0.8 bar
min. (absolute) must be adhered to. The boost pressure
relief valves for the rated sizes 55-135 are integrated in
the port plate housing, and for the rated sizes 210 and
280 in the charge pressure manifold of the HPV.

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

E2
The HPV 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.
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 dysfunction in the proportional magnets'
circuits, a similar reaction can be induced by the
intervention of the electronic control units.
Its use is recommended for mobile applications where
specific safety criteria have to be met in terms of travel
and coasting behavior, e.g. road traffic use.
