Attention:
Carefully apply these prescriptions.
3.1. General recommendations
• When transporting the compressor use proper slinging. Store the
compressor in stable places.
• Installation and maintenance must be carried out with the unit
totally disengaged from its drive system and must be performed by
qualified personnel.
• Use adequate clothing (avoid ties, loose sleeves, necklaces and
so on) and suitable protection equipment (gloves, protection glasses,
boots...).
• Before each maintenance operation, stop the pump and restore
the atmospheric pressure.
• Make sure that all the parts of the unit are idle and cool, before
performing any maintenance operation.
• To prevent errors and hazardous situations, establish what each
operator is responsible for in the different maintenance operations.
• Do not start the machine if the protection devices provided for
transmissions are removed. Replace damaged part.
• Final manufacturer must make the transmission inaccessible by
means of a fixed guard or interlocked movable guard.
• Operators working nearby must avoid prolonged exposure to the
noise emitted by the aspirator, if not equipped with the proper ear-
protection devices (IPDs recommended: ear protectors).
• When the pump is running, some parts may reach very high
temperatures (above 70°C). Use all necessary precautions to avoid
contact.
• Avoid accidental suction of solids: solids may be projected at high
speed through the exhaust manifold and cause injures. A filter must be
mounted on the suction line (Mesh 55).
• Pressure relief valve: point the air flux away from the operators.
• Do not use the aspirator over its designed limits: the machine may
be damage and the operator may be injured.
Do not exceed the speed and the power supply
parameters indicated in the technical tables (see
par 2.2 – 2.4).
• Based on the final use of the decompressor, the insertion in the
housing machine and the typology of the same, the designer of the
housing machine must apply safety signals (pictograms) to warn the
operator on the risk still present. These pictograms essentially refer to
three categories:
Signals prescribing the use of Individual Protection Devices (IPDs)
such as, in this case, the use of gloves and ear protectors.
Signals indicating to pay particular attention to the dangers related
to the machine’s components, such as: risk of dragging in the
transmission equipment and contact with hot surfaces.
Signals indicating specific parts of the machine for an easier
identification, such as: greasing points, oil tanks, etc.
3.2. Intended use
• The vacuum pumps RV are designed to convey filtered air into
systems for the vacuum production (example: systems for the suction
of powders or liquid wastes). Any other usage shall be considered
improper.
• Do not sack toxic substances and inflammable or explosive
gasses, since the internal components of the pump may reach high
temperatures.
Avoid suction of toxic (poisonous) explosive or
flammable gasses because internal components
may reach high temperatures.
• Avoid suction of liquids or solids; they can seriously damage the
pump.
Attention: liquids or solids infiltrations can
seriously damage the pump.
• Do not run the pump over its designed operating limits (see par.
2.5): it may break and transmission can be damaged.
3.3. Conveyed fluids
• RV are suitable for conveying filtered air. Before conveying other
kind of gases, verify compatibility with pump’s characteristics.
• The machine was not designed and built to operate in
environments with potentially explosive atmosphere (outdoor or
indoor).
• Please contact JUROP’s Technical dept. if necessary.

4.1. Checking upon receipt
• When the goods are delivered, make sure that all parts in perfect
condition and have suffered no damage during shipping.
• Make sure the vacuum pump has its identification plate affixed on
the front cover. Pumps without such identification are to be considered
anonymous and potentially dangerous: in such an event, they must not
be used, otherwise the manufacturer will be deemed free from any
liability whatsoever.
4.2. Storing in the warehouse
• If the pump will not be installed inside a short time after delivery:
Remove the guards from the ports and spray a film of protective oil
over the inner surfaces of the body, rotors and sides. Then attach
again the guards;
Store in a closed and dry place. Renew the preserving oil
periodically.
• To temporarily store a used pump, follow the instructions below:
Thoroughly clean the pump.
Equip the pump with suitable anti-corrosion protection.
4.3. Movimentazione e installazione
• Before each movement, verify that the lifting equipment has a
suitable capacity (check the weight of the decompressor, possibly
showed in this manual, in the paragraph 2.2).
• Do not lift the packaging or the machine when moving more than
50 cm from the ground. Proceed with the final lifting only near the
installation point.
• Harness the machine with suitable straps / chains near the main
body, paying attention to the position of the mass centre of gravity to
ensure the load stability.
Warning: do not stand under the machine when it
is lifted during the installation.
4.4. Mounting
• The mounted aspirator must be accessible for maintenance and
firmly fixed on a frame or angled base with a 3° max inclination on X
and Y axes (see Fig. 4.1). The structure must be fit to avoid flexions or
vibrations.
• Provide enough space for air ventilation and disposal of heat when
pump is running. See Fig. 4.2 and 4.3 for indication of the distance to
be respected.

• Provide the necessary space to reach all points of lubrication
control (oil level), and the oil tank filler cap, the lever of the 4-way
switch, vanes inspection ports.
• The oil tank is mounted on the suction side of the housing. Thus,
the rotary direction determines the pump overall dimensions. See also
paragraph 2.1.
• In case of RV with hydraulic motor, provide the necessary space
to disassemble the motor itself and proceed with joint lubrication.
Pic. 4.4
• In the event that the decompressor is electrically isolated, connect
it to the ground or make it equipotential with the housing machine.
Check that the paint does not prevent its passage.
4.5. Vacuum - pressure line
• See figure 4.5.
• In order to avoid the suction of liquids, a primary flow shutoff valve
(Pos. 1) and a secondary shutoff (Pos. 2) are to be mounted on the
suction line. If necessary, also apply a suction filter (Pos. 3) to prevent
solids from entering.
• The silencer (Pos. 4) applied to the pump exhaust - besides
reducing the noise level - is designed to separate the oil mist expelled
from the pump outlet port. The separator must be easily drained from
oil and condensate accumulated at regular intervals.
• The diameter of the vacuum or pressure line pipes must be
properly dimensioned to the pump flow and, in any case, it must be
larger than the diameter of the ports.
• The pipes weight or their dilatations must not solicit the pump
housing. Use high temperature resistant rubber connections.
• Before mounting, remove the port protections. All pipes and line
components must be clean.
• Avoid restrictions and tight curves as much as possible, if not
strictly necessary.
• Exhaust pipe can reach high temperatures. Hence, they must be
properly isolated.
• An over-pressure safety relief valve (Pos. 5) should be mounted in
order to prevent the overloading of the vacuum pump. Mount the valve
near the pump without applying any gate valves on the line.
• A vacuum relief valve (Pos. 6) should be applied to limit the
maximum vacuum rate at 80% in order to prevent the pump running at
continuous duty from overheating.
• Venting shutter (Pos. 9): it is also useful to cool down the
overheated pumps as well as for their internal wash-up. Direct the air
flow away from the operators.
• Thermostat (Pos. 8): it must be installed at maximum 150 mm from
the exhaust port. The sensitive element must reach the pipe centre.
Safety thermostat on manifold is supplied on request.

Hydraulic actuator installation
• Adjust movement speed using the two built-in valves.
• Use a closed-centre distributor or apply a block valve.
Pneumatic actuator installation
• Adjust movement speed by applying two unidirectional flow control
valves.
For both actuators
• Adjust speed: full rotation should not take less than 1 second.
• Fluid filtration: ensure a level equal to or greater than the
recommended value.
• In the event of a (hydraulic or pneumatic) supply failure, the
suction unit inverter will remain in the same position it was when the
failure occurred.
Pic. 4.6
Maintenance
• The diverter is adjusted before shipment and does not usually
require further adjustments.
• Diverter lubrication:
Use NLGI 2 Lithium grease. Quantity: 80-100 grams for 1000
working cycles.
A bleeder hole covered by a filter is preventing the hole to
overfill. Clean the filter whenever clogged.
• Hydraulic actuator: the control valves are equipped with an internal
metal filter. Disassemble and clean if movement stops.
• Pneumatic actuator: for non-dried air, use temperature 0 ÷ +80°C.
• The following figure shows a possible schematic view of a correct
hydraulic connection.
Pic. 4.7
• The following figure shows a possible schematic view of a
pneumatic connection.
Pic. 4.8
• In case of interruption of the pneumatic or hydraulic supply, the
inverter of the suction unit remains in the same position it was when the
failure occurred
4.7. Pump mounting - Drive connection
A) Cardan shaft drive
• Use telescopic cardan shafts.
• In order to achieve a uniform motion of the driven shaft, the
following requirements must be met (see Pic. 4.8):
Equal working angle α and α1of both couplings;
The internal fork joints must be coplanar;
Both driven and driving shafts must be coplanar.
Pic. 4.9
• It is also recommended working with limited articulated joint angles
(max 15° at 1000 rpm and max 11° at 1300 rpm) and disengaging the
transmission for those operations requiring great angles (steering or
lifting).
Follow the rotation direction as indicated on the
pump front conveyor protection. Follow the
instructions of the cardan shaft’s manufacturer.
• Use the cardan guard supplied with the pump, by fixing it to the
pump itself.
Use the cardan guard supplied with the pump, by
fixing it to the pump itself. In any case, the
installation, by the final installer, must comply
with the current EC accident prevention
regulations and must be compatible with the
geometry of the protection cap supplied with the
machine.

B) Belt drive
Pic. 4.10
• Install a suitable pulley on the smooth shaft as close as possible
to the pump: 50 mm. Taper lock pulley are suggested.
• Apply an adequate belt tension (see manufacturer’s data). See list
belove (T. Max).
• Do not use diven or driving pulleys with a pitch diameter inferior to
160 mm. Small pulleys require a high belt tension, which may cause
premature wear to the bearing or transmission damages.
• Let the air circulate freely to cool down the pump. Provide
protections, which ensure adequate ventilation.
• A limited speed ratio will extend the belts life and reduce stress on
the shafts. When possible prefer:
Pulleys with a pitch diameter bigger than the one indicated,
Dp=180mm;
Engines or power take-offs with a speed similar to the one of the
pump.

• Check the oil tank level.
• Increase pressure and rotation speed until operating values are
reached.
• The machine/system manufacturer is responsible for dimensioning
the lines.
The machine/system manufacturer is responsible
for dimensioning the lines.
5.1. Starting-up of the pump
• Check the side mounted tank oil level.
• Riempire il serbatoio olio sino al livello massimo.
• In order to choose the most suitable oil, see paragraph 2.6.
• Check that all protection devices are correctly installed.
• Check that there are no obstacles in the vacuum line.
• Check rotation direction: open all system valves and start running
slowly.
Do not rotate in the wrong direction: this may
damage the vacuum pump. Follow the arrow
indicated on the front flange.
• Check which position of the four-way integrated valve lever allows
vacuum or pressure functioning.
• Close the valve and increase vacuum rate (or operating pressure).
• Check loading and operating speed for vibrations or unusual
noises.
This vacuum pump is designed to work at
maximum speed, but for longer operating we
recommend the pump be run at working speed
(see par. 2.5).
• To reduce the vacuum rate to 80% max.
• Prepare adequately transmission.
5.2. Operating precautions
• Run the vacuum pump at a room temperature of -20°C e +40°C.
• Running at continuous duty: see paragraph 2.2.
• Do not make the vacuum pump overheat. Maximum air
temperature on exhaust (or delivery) side: 160- 180°C.
• If maximum temperature allowed is reached, in order to prevent
damages to the internal parts, it is recommended:
To reduce the vacuum rate or the working pressure by opening the
venting port;
To reduce the pump speed according to list at paragraph 2.4.
To start running the pump again only when temperature at exhaust
is below acceptable values.
• Do not operate the pump without lubrication: it may cause quick
wear and possible breakdown of vanes.
• Do not start running the pump under load: that causes stress to the
drive system and the hydraulic motor.
• Check rotation speed. The vacuum pump must:
Never exceed the maximum speed: it may cause overheating;
Never run below the minimum speed: this may cause an
anomalous wear of the housing;
• Do not accidentally operate the pump in the wrong direction: it may
break the vanes.
• Do not convey the exceeding delivery outlet towards the suction
port, otherwise it will sack warm gas.
• In vehicles do not direct compressor’s discharge to the intake of
the engine.
• Control the air flow by adjusting the rotation speed: do not use the
pressure relief valve to discharge the exceeding flow.
• Once the needed vacuum rate has been reached, we recommend
reducing the vacuum pump speed to its working speed (see par. 2.4):
this allows keeping the achieved vacuum/pressure rate constant. The
pump speed can also be reduced to values lower than the working
speed during the tank discharging phase (with the 4-way valve in
pressure mode) without increasing the draining time.
• Thus, exhaust temperature is reduced, vane durability is increased
and both oil consumption and power absorption are reduced.
Once the needed vacuum rate has been reached,
we recommend reducing the vacuum pump
speed to its working speed.
• After operation in dusty environments, after accidental sucking of
liquids inside the pump or before a long inoperativity period it is
recommended to wash the pump inside according to the following
procedure:
1. Before washing the pump, be sure that it has cooled down. To
obtain this in a short time, it is possible to run the pump for a few
minutes at zero vacuum conditions, or stop it at all;
Attention: Do not carry out this operation on very
hot pumps (for example after a working day) until
they have cooled down.
2. Use 1-2 liters of water mixed with a non-flammable detergent. We
suggest some product like Henkel Bonderite C-NE 5225: 5%
concentration in water. This detergent grants a good protection
against rust and oxidation.
3. Use one of the openings placed in the vacuum line (closet on the
pump) to suck some water mixed with detergent.
4. Start the pump at low speed leaving opened all the suction valves
in the tank, in order to keep low the vacuum rate (max vac. 10-
20%). Let the detergent mix entering the pump very slowly.
5. The detergent mix stays suspended in the pump inside, before
being expelled through the exhaust silencer.
6. After keeping the pump speed for a while to make the product
reaching the internal parts, it is necessary to dry the pump
preventing oxidation. When the detergent mix is finished, continue
running the pump at the lo west possible vacuum rate for a few
minutes, then close venting and suction valves up to 50-60%

maximum, for a couple of minutes. With this operation the pump will
dry from the heated air and protected from the chemical attack of
the detergent.
7. Washing the pump with this detergent guarantees a protection after
some days of inoperativity. If the pump is not used for more than
two weeks, after having washed and dried the inner parts as
described above, it is recommended to suck slowly 200 cc anti-rust
and water-repellent protective oil (or, if not available, a very fluid
gear oil).
Attention: do not carry out also this operation on
very hot pumps (for example after a working day)
until they have cooled down.
In case the exhaust line cannot be disconnected,
drain the liquids accumulated in the separator of
the exhaust silencer.
6.1. Ordinary maintenance
• Any interventions must be performed when the machine is cold, stopped and switched off.
• Installation and maintenance must be operated only by qualified personnel wearing the proper clothes and the necessary tools as well as
protection devices.
• Use suitable protection equipment (gloves, protection glasses, boots...)

Checking the vanes wear
• Unscrew the vanes wear check-plug on the front flange. Pic. 6.2.
• Turn the shaft by hand until vanes appearance.
• Vanes usually slip on seat bottom due to gravity. Check their right
entry in the seat.
Pic. 6.2
• Inserire, come in Fig. 6.3, un’astina Ø 5 mm con l’estremità conica
verso l’interno della pompa (astina in dotazione).
• Insert a Ø 5 mm stick until it touches the rotor and then mark (see
Fig. 6.3).
• Turn the rotor slowly until the stick touches the vane in idle
position in its seat. The vanes slide to the bottom of the seat due to
gravity: check they really do and mark again on the stick.
• Repeat the same procedure for all the vanes. If wear exceeds 10
mm: replace the vanes as soon as possible.
Pic. 6.3
• Maximum acceptable wear: 12 mm. Immediately replace: vanes
are likely to break down.
• Replace all the pump vanes at the same time.
Replace the vanes when their wear exceeds 12
mm (L – L min): they may break. Replace all
vanes at the same time.
• Replace the cap after the measurement.
6.2. Extraordinary maintenance
• Except for the cases described below, extraordinary maintenance
on a RV must be carried out by specialized personnel only; otherwise
the guarantee will be invalidated.
• All extraordinary maintenance interventions must be carried out
when the machine is cold, stopped and switched off. Implement the

order to lower it (in case of excessive play between the valve and its
seat and of reduced performance) or anticlockwise by 1/8 turn (45°) to
raise it (in case of difficult rotation of the valve in its seat).
• Hold the valve in place with the spanner and fasten the nut (P4)
above the ferrule.
Pic. 6.7
• Remove the screw which temporarily blocks the ferrule and check
for the correct rotation of the valve by adjusting the shaft frame. Repeat
the valve adjustment, if necessary.
Attention: get the valve back into the previously
“marked” position. Otherwise, the valve may
work improperly.
• The valve - in both its end stroke positions - must separate the air
flow sucked from the pump outlet air. The pump may be started in
order to check for the proper functioning.
