• The PN Series decompressors are designed for agricultural use (tanker outfitting) but can also be used in industrial applications (lorry
outfitting).
• The technology applied is that of rotary vane pumps: the rotor, equipped with moving vanes, rotates eccentrically inside the pump body. The
vanes are kept in contact with the internal surface of the body by the centrifugal force. Between the vanes and the body there is always an oil film
that acts as a sealing and lubricating element.
• Lubrication is forced with a gear pump and adjustable oilers; the shaped pipes are made of copper, while the intake and exhaust conveyors are
made of aluminium. The oil tank is built into all models; on request, the PN 106 model can be supplied with a side oil tank and automatic lubrication
system with a volumetric metering pump.
• The PN Series decompressors are air-cooled. Cooling takes place with a natural air flow on the outer fins of the body, made of high strength
cast iron.
• The check valve is integrated in the decompressor.
• The decompressors feature a 4-way manifold. On request, a 5-way Mixer-type diverter valve is provided, designed for mixing the liquid in the
tank of the tanker while it is being distributed on the ground.
• Transmission:
- Direct with smooth or splined shaft.
- Gearbox transmission (ASAE 1” 3/8) 540 or 1000 rpm.
- With belts: the pulley must be fitted on the conical shaft of the pump.
- Electric, hydraulic motor or with auxiliary motor.

Attention: carefully apply these prescriptions.
3.1 General recommendations
• When transporting the compressor use proper slinging. Store the
pump 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 - 2.3).
• Based on the final use of the pump, 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
• Vacuum pumps of the PN series are commonly used on stationary
or mobile equipment for suction and transfer by means of vacuum or so
called pneumatic-transportation of liquid and solid wastes. Any other
usage shall be considered improper.
• As cooling is given by atmospheric air, pumps are foreseen for
non-continuous duty; suggested uninterrupted working-time: about 15
minutes. Overheating of the pump will cause serious damages of the
same and/or blocking of the rotor. The model PN do not accept
operating temperatures over 150 °C (300 °F), checked at not more
than 150 mm from the discharge connections.
• Do not sack toxic substances and inflammable or explosive
gasses, since the internal components of the pump may reach high
temperatures.
Do not sack toxic substances and inflammable or
explosive gasses, since the internal components
of the pump 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.
2.3): it may break and transmission can be damaged.
3.3 Conveyed fluids
• PN 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. Compulsory accessories
• Compulsory accessories for a correct running of the pump:
Safety filter mounted between the pump and the secondary
shutoff.
Over-pressure safety relief valve.
4.2. Checking upon receipt
• When the goods are delivered, make sure that all parts listed on
the delivery note are in perfect condition and have suffered no damage
during shipping.
• Remove the parts of the packaging that can be dangerous if
sucked by the compressor.
• Make sure the vacuum pump has its identification plate. 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.
4.3. Storing in the warehouse
• If the pump will not be installed inside a short time after delivery:
Store in a closed and dry place.
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.
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.
4.4. Handling and installation
• Before each movement, verify that the lifting equipment has a
suitable capacity (check the weight of the pump, 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.
4.5. Mounting
• The pump must be assembled for an easy access for maintenance
operations and secured rigidly to a frame or levelled base (max. 3°
slant to the horizontal plane. See Fig. 4.1). The base must be such as
to avoid vibrations, bending or deformation.
• It is recommended to install the pump on vibration adsorbing pads
to reduce the noise and vibrations produced during its operation.
• Leave enough space around the pump to allow the free circulation
of air for cooling; avoid exposure to dirt and debris.
• 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. See Pic. 4.1.
• The oil tank is mounted on the rear side of the pump. Instead for
PN 106 the oil tank is mounted on the suction side of the housing.
• Provide for suitable manoeuvring spaces of the inverter lever. The
control lever has two possible switching positions well defined by the
latches and numbers reported on the fusion. It is directly connected to
the internal diverter tang of the inverter, making it very intuitive: 90° of
the lever switching corresponds to 90° of the inverter switching.
• Based on the functionality of the system which will house the
decompressor, the designer of the end machine, must:
Properly signal the functionality of the inverter according to the
position of the manual operating lever or of the pneumatic
actuator or of the hydraulic one.
Install suitable pressure and / or vacuum restrainer valves near
the inlet and outlet points of the machine.
• In the event that the pump 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.
