General specifications
Experience acquired in designing mini power packs, and a
research effort aimed constantly at satisfying the technical
specifications of our customers: these assets have provid
ed the principal resource for development of the UP40 pow
er packs:
- compact dimensions achieved through detailed analy
sis of the geometries involved, and the components used;
- economy of the manufactured product, gained by
adopting innovative technologies and by standardizing
valve cavities with those of the major hydraulic components
manufacturers;
- the assurance of constant quality, thanks to compre
hensive control on materials and production cycles.
Power packs are widely used in mobile applications.
The UP40 is suitable for applications where short opera
tions and middle-high pressure are required.
Invalid Lift Equipment is a good example, where the com
pactness of the unit is a particular advantage in view of the
limited space available.
The need for fluid power in mobile machines means that
power packs can be exploited in the widest variety of
applications: lift platforms, and equipment for handling high
and bulky loads in general.

WARNING!
Bucher Hydraulics is not responsible for misuse or mis
application of product. Pressure values, type and number
of cycles have to be considered before choosing the type of
product. For any question about applications, please con
tact Bucher Hydraulics.
All the installation and maintenance operations of par
tially completed machinery must be made by technically
competent personnel.
The hydraulic power units due to its construction does
not perform the function of the safety component.
So the user must insert safety components into the machine
to protect against the possibility of breakage during opera
tion.
The hydraulic power units can not function indepen-
dently and are designed to be integrated into hydraulic
systems.
Fluids should be contained and disposed of properly.
Prior to performing any maintenance make sure the
equipment is turned off and that any stored energy, for
example pressure, is released. Also, extended equipment
or cylinders should be lowered and mechanically locked as
required.
During the handling of the hydraulics power units, do not
lift the unit by the valves mounted on it (see the figure 1, the
arrows indicate the points to lift). Always wear appropriate
safety gloves and footwear. Wait if the motor is hot.
Always wear eyes protection and protective clothing
when working on and around hydraulic systems.
Remove jewellery and objects that might conduct elec
tricity while working on power units.
Hydraulic fluid does pose a fire hazard, can cause
burning or skin irritation if not properly handled.
Fluid under pressure can pierce the skin and enter the
bloodstream causing death or serious injury.
Devices being operated by the hydraulic system should
be immobilized so they cannot move and cause injury while
being inspected or repaired. Disconnect from electrical
source.
The above warnings are to be adhered to in order to reduce
the risks resulting from the normal usage of the hydraulic
power units for the safety and health of the users.
The product you have purchased is guaranteed for a period
according to existing regulations.
The warrant will be void if the product has been installed or
used in a manner not in accordance with our instructions,
or if it was tampered with, modified, subjected to usage out
side those prescribed.

Temperature (_C) 90 105 120 130 155 180
Type of duty:
To ensure selection of the electric motor best suited to a
given set of operating conditions, the duty cycle needs to be
verified. Duty cycles S1, S2 and S3 are defined below in ac
cordance with CEI 2-3
Continuous duty S1:
Operation on-load (steady conditions) for a period of indef
inite duration, during which the motor reaches thermal equi
librium without exceeding the maximum permissible tem
perature.
Short time duty S2
Operation on-load (steady conditions) for a period of limited
duration, denoted td in the diagram, during which maximum
permissible temperature is reached, followed by an off-load
period of duration sufficient for the temperature of the motor
to return to ambient temperature.
Intermittent duty S3
A sequence of identical cycles, each 10 minutes in duration,
the single cycle comprises a period of operation on-load td,
during which the motor may reach its maximum permissible
temperature, is reached, followed by an off-load period of
limited duration tm, insufficient for the temperature of the
motor to return to ambient temperature.
The value of S3 indicates the duration of the on-load period
td in relation to the overall cycle time tp, as a percentage.

5.1.3 Example of how the graphs are used
Required data
Flow rate Q = 3 l/1'
Pressure p =100 bar
Pump displacement
Determined by the intersection of the required p and Q
curves.
In the example indicated, pump AP05/0.75 has the required
p and Q specifications.
In the event that there is no point of intersection with any
curve, a displacement as near as possible to the required
flow rate should be selected.
Current consumption
This is determined by taking a vertical line from the pressure
value to its point of intersection with the I curve correspond
ing to the selected displacement.
In the example illustrated, current consumption is:
I = 45 Ampere
Type of use
Having established the current, the relationship of the S2
and S3 curves will give the following values:
S2 = 6 min. S3 = 11.5%
Terminals
Unless otherwise stated, d.c. motors supplied by Bucher
Hydraulics S.p.A. have two terminals.
Poles are identified in accordance with IEC34-8
A1 - A2 Armature
D1 - D2 Series
B1 - B2 Poles
E1 - E2 Parallel

5.1.4 Mounting directions
The tie bolts must not be withdrawn completely
while fitting motor, but retracted just for a short
distance (30-50 mm max).
Once fitted to the power pack, the motor should be run
off-load momentarily (5 seconds max) to verify its correct
operation: supply power to the windings and measure the
current drain, which must not exceed 35 Ampere.
Power cable
The wire selected for power connections must be of cross
section appropriate for the rated current of the motor.
Tightening torques
When assembling the motor and power pack and securing
the wires of the power cable to the motor terminals, observe
the tightening torque values indicated.
Brush life
The brushes will wear down progressively with continued
operation of the motor, and must be replaced when reduced
to their minimum useful length.
Since the rate of wear on the brushes is dictated by the
operating conditions and cannot therefore be broadly spe
cified, consult our Sales Department for guidance.

5.1.5 Starter Relays - Technical information
Versions:
Available voltage: 12-24 V
See relative table for technical data for:
- Electrical insulation class
- Type of duty
- Protection factor:
The level of protection is defined according to the same
parameters as listed for electric motors.
Contact life:
The contacts of the relay will wear down progressively dur
ing operation.
Since the rate of wear is dedicated by the type of duty and
cannot therefore be broadly specified, consult our Sales
dept. for guideline information.
Fitment to electric motor
Starter relays can be fitted to the frame of the motor by a
metal clip.
The relay is secured by means of a clip encircling the motor
frame and inserted through special slots in the feet of the re
lay itself.
In this instance, several mounting positions are possible.
Electrical diagram
A typical arrangement for connection of the relay to the elec
tric motor is shown in the diagram.

This chapter includes all technical information relating to
valves for use in conjunction with the housings described in
section 1.
Complete the designation codes for the selected valves ac
cording to the technical information and guidelines given for
each component.
Illustrated here by way of example is a correct and complete
compilation for section 7 of the hydraulic power pack desig
nation form.

7.1.1 Materials
Bucher Hydraulics cartridge valves are manufactured using
steel of high mechanical strength. Friction and potential
wear are minimized by special heat treatments. Surface
heat treatments protect parts exposed to the external envir
onment. Standard seals are NBR (Buna N), with backup
ring in PTFE. For application requiring special compound
FPM (Viton) etc. consult Bucher Hydraulics.
7.1.2 Indication for use
Use mineral oil based hydraulic fluids to ISO/DIN standard,
only. Recommended viscosity range: 20-120 mm
2
/s (cSt)
maximum viscosity 700 mm
2
/s (cSt).
For different fluids and operating conditions, consult our
Sales Dpt.
All valves showed in the present catalogue are marked with
correct flow direction, please observe it always. Valves
must never be tampered with or modified.
Any unwarranted interference may adversely affect the
safety and correct operation of the entire system.
External seals and backup rings are user-serviceable.
The appropriate replacement kit is indicated for each valve.
Before installing a valve in its cavity, ensure that the body
and all components of the system are clean.
Smear external seals lightly with grease, and check that any
filters installed are correctly positioned.
Tighten the valve to the specified torque setting.
7.1.3 General technical information
All valves with leakage-free operating characteristic are
100% factory tested.
Nonetheless, the guaranteed maximum leakage may be
exceeded if the valve is installed in a system with inad
equate filtration.
Pressure, drops and other general performance indicated
in the catalogue are referred exclusively to the component.
In the case of valves subject to adjustable setting, such as
the pressure relief and if not specified in the order, we set
them according to standard setting values indicated at sec
tion 7.2.1 .
7.1.4 Solenoid valves
The correct selection of the solenoid valve is related to the
maximum flow rate and operating pressure values.
In a system with a single acting cylinder, therefore, it must
be considered that the effective rate of flow through the un
loading solenoid valve is not the flow delivered by the pump,
but rather the momentary flow exhausted from the cylinder,
or the restricted flow needing a pressure-compensated flow
control valve, if installed.
The nominal voltage is the value indicated on the solenoid.
Effective voltage must be measured at the terminals of the
solenoid connector.
A maximum allowed voltage tolerance of ±10% in relation
to the nominal value is accepted.
Incorrectly power supply components and cables (which
length has to be as shorter as possible) and/or low battery
charge can cause not correct solenoid valve operation.
Standard solenoids valves are designed for D.C. operation.
A.C. supply requires a connector with bridge rectifier in
cluded. When energized with A.C. voltage, the solenoids
can operate at 50 or 60 Hz frequency, without distinction.
The connection used for standard solenoids are to EN
175301-803 (ex DIN 43650).
For solenoid with different connections (Amp Junior Timer,
Direct Wiring, etc.) can be supplied on request, after agree
ment with Bucher Hydraulics, please contact our Slaes De
partment.
The solenoid can be rotated through 360°, and the con
nector EN 175301-803 (ex DIN 43650) positioned at 90° in
tervals.
Specified performance datas were recorded in stabilized
solenoid operated temperature and voltage at the -10% of
the nominal value.
All solenoid valves are fitted with protective O-rings in
stalled between the tube and the solenoid.
This protects internal parts from condensation and contam
inants, which could cause malfunction.
Standard solenoids are not suitable for operation in environ
ments where there is any risk of explosion (see Directives
and standards)

7.1.5 General notes on D.C. power input
A swift and secure coupling is obtained using the special
connector (type 200544110009).
The cable coming from the D.C. power source (batteries,
rectified a.c. main supply, etc.) must be connected as indic
ated in the diagram (figure 1).
The negative and positive polarity of the wire need not be
verified for connection purposes.
The connector incorporates a terminal for earthing the
solenoid.
It is important to check that the grommet and armour clamp
nut are correctly assembled (figure 2), as this prevents the
cable being wrenched from connector.

The purpose of a relief valve is to keep the maximum
system pressure at a safe level. When the hydraulic power
unit is supplied with pressure relief valves, the correct calib
ration is provided by Bucher Hydraulics S.p.A. and there are
no reasons to change this value.
* Max pressure admitted as single valve inside UP40 power:
190 bar (peak 230 bar, see section 2.2).
Pressure setting
For preset values other than those indicated, replace the
first two digits of the designation with the setting required.
For example, required setting 150 bar: designation type
15VMD. Always check that the required value falls within
the standard ranges of adjustment.
