Attention: caref lly apply these prescriptions.
3.1. General recommendations
• When tr nsporting the compressor use proper slinging. Store the
compressor in st ble pl ces.
• Inst ll tion nd m inten nce must be c rried out with the unit
tot lly diseng ged from its drive system nd must be performed by
qu lified personnel.
• Use dequ te clothing ( void ties, loose sleeves, neckl ces nd so
on) nd suit ble protection equipment (gloves, protection gl sses,
boots...).
• Before e ch m inten nce oper tion, stop the pump nd restore
the tmospheric pressure.
• M ke sure th t ll the p rts of the unit re idle nd cool, before
performing ny m inten nce oper tion.
• To prevent errors nd h z rdous situ tions, est blish wh t e ch
oper tor is responsible for in the different m inten nce oper tions.
• Do not st rt the m chine if the protection devices provided for
tr nsmissions re removed. Repl ce d m ged p rt.
• Fin l m nuf cturer must m ke the tr nsmission in ccessible by
me ns of fixed gu rd or interlocked mov ble gu rd.
• Oper tors working ne rby must void prolonged exposure to the
noise emitted by the spir tor, if not equipped with the proper e r-
protection devices (IPDs recommended: e r protectors).
• When the pump is running, some p rts m y re ch very high
temper tures ( bove 70°C). Use ll necess ry prec utions to void
cont ct.
• Avoid ccident l suction of solids: solids m y be projected t high
speed through the exh ust m nifold nd c use injures. A filter must be
mounted on the suction line (Mesh 55).
• Pressure relief v lve: point the ir flux w y from the oper tors.
• Do not use the spir tor over its designed limits: the m chine m y
be d m ge nd the oper tor m y be injured.
Do not exceed the speed and the power s pply
parameters indicated in the technical tables (see
par. 2.2 - 2.3).
• B sed on the fin l use of the decompressor, the insertion in the
housing m chine nd the typology of the s me, the designer of the
housing m chine must pply s fety sign ls (pictogr ms) to w rn the
oper tor on the risk still present. These pictogr ms essenti lly refer to
three c tegories:
- Sign ls prescribing the use of Individu l Protection Devices (IPDs)
such s, in this c se, the use of gloves nd e r protectors.
- Sign ls indic ting to p y p rticul r ttention to the d ngers rel ted
to the m chine’s components, such s: risk of dr gging in the
tr nsmission equipment nd cont ct with hot surf ces.
- Sign ls indic ting specific p rts of the m chine for n e sier
identific tion, such s: gre sing points, oil t nks, etc.
3.2. Intended se
• V cuum pumps of the PNR/PNE series re commonly used on
st tion ry or mobile equipment for suction nd tr nsfer by me ns of
v cuum or soc lled pneum tic-tr nsport tion of liquid nd solid w stes.
Any other us ge sh ll beconsidered improper.
• They re ir-cooled nd consequentely foreseen for non-
continuous duty. The mod. PNE nd the mod. PNR, the l tter supplied
with ir injection system (fig. 1) nd me nt for he vy duty works, do not
ccept oper ting temper tures over 150 °C (300 °F), checked t not
more th n 150 mm from the disch rge connections.
• Do not s ck toxic subst nces nd infl mm ble or explosive
g sses, since the intern l components of the pump m y re ch high
temper tures.
Avoid s ction of toxic (poisono s) explosive or
flammable gasses beca se internal components
may reach high temperat res.
• Avoid suction of liquids or solids, they c n seriously d m ge the
pump.
Attention: liq ids or solids infiltrations can
serio sly damage the p mp.
• Do not run the pump over its designed oper ting limits (see p r.
2.3): it m y bre k nd tr nsmission c n be d m ged.
3.3. Conveyed fl ids
• PNR/PNE re suit ble for conveying filtered ir. Before conveying
other kind of g ses, verify comp tibility with pump’s ch r cteristics.
• The m chine w s not designed nd built to oper te in
environments with potenti lly explosive tmosphere (outdoor or
indoor).
• Ple se cont ct JUROP’s Technic l dept. if necess ry.

4.5. Mo nting
• The pump must be ssembled for n e sy ccess for m inten nce
oper tions nd secured rigidly to fr me or levelled b se (m x. 3°
sl nt to the horizont l pl ne. See Fig. 4.1). The b se must be such s
to void vibr tions, bending or deform tion.
• It is recommended to inst ll the pump on vibr tion dsorbing p ds
to reduce the noise nd vibr tions produced during its oper tion.
• Le ve enough sp ce round the pump to llow the free circul tion
of ir for cooling; void exposure to dirt nd debris.
• Provide the necess ry sp ce to re ch ll points of lubric tion
control (oil level), nd the oil t nk filler c p, the lever of the 4-w y
switch, v nes inspection ports. See Pic. 4.1.
• For PNR/PNE 73-83-104-124 the oil t nk is mounted on the re r
side of the pump. Inste d for PNR142 the oil t nk is mounted on the
suction side of the housing.
• Provide for suit ble m noeuvring sp ces of the inverter lever. The
control lever h s two possible switching positions well defined by the
l tches nd numbers reported on the fusion. It is directly connected to
the intern l diverter t ng of the inverter, m king it very intuitive: 90° of
the lever switching corresponds to 90° of the inverter switching.
• B sed on the function lity of the system which will house the
decompressor, the designer of the end m chine, must:
- Properly sign l the function lity of the inverter ccording to the
position of the m nu l oper ting lever or of the pneum tic
ctu tor or of the hydr ulic one.
- Inst ll suit ble pressure nd / or v cuum restr iner v lves ne r
the inlet nd outlet points of the m chine.
• In c se of PNR/PNE with hydr ulic motor, provide the necess ry
sp ce to dis ssemble the motor itself nd proceed with joint lubric tion.
• In the event th t the decompressor is electric lly isol ted, connect
it to the ground or m ke it equipotenti l with the housing m chine.
Check th t the p int does not prevent its p ss ge.
• The m chine expels g s during delivery t temper tures th t c n
re ch the m ximum permitted v lues for oper tion, with its lubric ting
oil in suspension. Oil consumption is st ted in p r gr ph 2.2, the
qu ntity of consumed oil corresponds to the qu ntity of oil emitted t
delivery.
4.6. Vac m / Press re line
• See the following picture.
• The hoses connecting the suction nd exh ust ports of the
v cuum pump must be of degu te di meter (suggested not less th n
3”) nd of oil nd corrosion resist nt m teri ls nd before connecting
them, m ke sure th t they re perfectly cle n in the inside.
• The weight or dimensions of the pipes must in no w y stress the
PNR/PNE body. Use high temper ture resist nt rubber sleeves.
• Remove the port gu rds when mounting. The pipes nd
components of the whole line must be cle n.
• Avoid constrictions nd tight curves where they re not essenti l.
• Connect the pump to the t nk through the suction m nifold which
h s thre ded port for fitting the over-pressure v lve.

• The exh ust pipes c n re ch high temper tures. Protect those
dequ tely from the oper tor re ch.
• A cl pet v lve on suction pipe voids rot tion in the opposite
direction when the pump stops.
• To void th t foreign liquids will enter the v cuum pump it is
necess ry to mount on the suction line n over-flow v lve of “flo ting-
b ll” type (Fig. 4.2. - pos. 1). The flow section of this v lve must be
equiv lent to the suction hose’s one.
• It is lso necess ry to h ve on the line suit ble ir filter for
preventing solids to be sucked inside the v cuum pump. It is lso
recommended to mount “second ry shutoff” of flo ting-b ll type (Fig.
4.2 - pos. 2) between v cuum pump nd over-flow (prim ry shutoff),
long with the previously mentioned ir filter (Fig. 4.2 - pos. 3).
• C lled lso 4-w y v lve, norm lly is m nu lly oper ted but it c n
be t ny time tr nsformed in pneum tic lly or hydr ulic oper ted upon
request of the ppropri te kit.
• During norm l running of the pump the resulting noise should be
reduced by me ns of suit ble silencer (Fig. 4.2 - pos. 4) mounted s
close s possible to the pump itself. It h s to be dimensioned for the ir
flow produced by the pump model. The oil used for the pump’s inside
lubric tion h s to be sep r ted from the exh usted ir by me ns of n
dequ te oil-sep r tor, pl ced directly inside the silencer. The silencer
is fitted lso with dr ining t p for the collected oil nd condensed
liquids.

5.1. P mp starting- p
• Before st rting the equipment check the lubric ting oil level of the
pump by me ns of the proper dip stick.
• Refill the t nk with lubric tion oil.
• Check the oil level in the ge r box (if the pomp is provided with it).
• In order to choose the most suit ble oil, see p r gr ph. 2.5.
• Check th t ll protection nd s fety devices re correctly inst lled.
• Check th t no obst cles obstruct the v cuum nd pressure line or
the ir injection cooling system.
• Check rot tion direction: open ll system v lves nd st rt running
t slow speed.
Do not rotate in the wrong direction: p mp may
be damaged.
• Check which position of the 4-w y integr ted v lve lever llows
v cuum or pressure functioning.
• Close the v lve nd incre se v cuum r te (or oper ting pressure).
• Check lo ding nd oper ting speed for vibr tions or unusu l
noises.
This vac m p mp is designed to work at
maxim m speed. For longer operating we
recommend the p mp be r n at working speed.
• Prep re dequ tely tr nsmission.
5.2. Operating preca tions
• Run the v cuum pump t room temper ture of -20°C e +40°C.
• Do not m ke the v cuum pump overhe t. M ximum ir
temper ture on exh ust (or delivery) side: 160-180°C.
• Do not oper te the pump without lubric tion: it m y c use quick
we r nd possible bre kdown of v nes.
• Do not st rt running the pump under lo d: th t c uses stress to the
drive system nd the hydr ulic motor.
• Check rot tion speed. The v cuum pump must never exceed the
m ximum speed or run below the minimum speed.
• Do not ccident lly oper te the pump in the wrong direction: it m y
bre k the v nes.
• Do not convey the exceeding delivery outlet tow rds the suction
port, otherwise it will s ck w rm g s.
• Control the ir flow by djusting the rot tion speed: do not use the
pressure relief v lve to disch rge the exceeding flow.
• Once th t the w nted v cuum r ted h s been tt ined it is
recommend ble to decre se the speed, (see p r. 2.3). This useful
procedure, th t will not incre se the time requested to fill up the t nk,
will however result in lesser we r of the v nes. It is suggested to
reduce the speed lso when oper ting with pressure.
• When, exh ust temper ture is reduced, v ne dur bility is
incre sed nd both oil consumption nd power bsorption re reduced.
Once the needed vac m rate has been reached,
we recommend red cing the vac m p mp
speed to its working speed.
• After oper tion in dusty environments, fter ccident l sucking of
liquids inside the pump or before long inoper tivity period it is
recommended to w sh the pump inside ccording to the following
procedure:
1. Before w shing the pump, be sure th t it h s cooled down. To
obt in this in short time, it is possible to run the pump for few
minutes t zero v cuum conditions, or stop it t ll;
Attention: Do not carry o t this operation on very
hot p mps (for example after a working day) ntil
they have cooled down.
2. Use 1-2 liters of w ter mixed with non-fl mm ble detergent. We
suggest some product like Henkel Bonderite C-NE 5225: 5%
concentr tion in w ter. This detergent gr nts good protection
g inst rust nd oxid tion.
3. Use one of the openings pl ced in the v cuum line (closet on the
pump) to suck some w ter mixed with detergent.
4. St rt the pump t low speed le ving opened ll the suction v lves
in the t nk, in order to keep low the v cuum r te (m x v c. 10-
20%). Let the detergent mix entering the pump very slowly.
5. The detergent mix st ys suspended in the pump inside, before
being expelled through the exh ust silencer.
6. After keeping the pump speed for while to m ke the product
re ching the intern l p rts, it is necess ry to dry the pump
preventing oxid tion. When the detergent mix is finished, continue
running the pump t the lo west possible v cuum r te for few
minutes, then close venting nd suction v lves up to 50-60%
m ximum, for couple of minutes. With this oper tion the pump will
dry from the he ted ir nd protected from the chemic l tt ck of
the detergent.
7. W shing the pump with this detergent gu r ntees protection fter

fl nged version (without m nifold with 4-w y v lve nd non-return v le),
it is dvis ble to intercept the working line of the m chine when it is
stopped, to prevent contr ry rot tions until the reb l ncing of the
pressures. The interception c n t ke pl ce through controlled v lve or
n utom tic unidirection l v lve (swing v lve).
• Avoid st rting the pump under lo d: motor nd drive system c n be
excessively stressed.
• With temper ture below 5 °C (40 °F) nd long periods of in ctivity,
introduce some qu ntity of oil through the suction connection before
st rting off the pump.
• The ir injection cooling system gr nts the use of the v cuum
pump t high v cuum r tes. Anyw y it h s to be remembered th t the
pump h s been designed for non-continuous work. This cooling system
llows to dissip te p rt of the ccumul ted he t still t s tisf ctory
lubric tion conditions. Continuous, he vy-duty work, or prolonged work
periods will c use n over-he ting of the pump, consequently reducing
perform nces nd dur bility.
• With the PNR models it is quite norm l th t the v cuum r te in the
t nk will f ll down t bout 50%, if nd when the pump is stopped for
sufficient time. This bec use tmosferic ir will flow b ck in the t nk
through the injection v lves, which re djusted t pproxim tely 0,5

the pump in order to void b ck rot tion of the pump.

recommended to w sh the pump inside ccording to the procedure
described t p r gr ph 5.2.
Checking the oil tank level
• Before st rting the m chine, check the lubric ting oil level.
Pic. 6.1
• Do not run the pump with oil level under the minimum level: th t
m y le d to dry functioning nd c use serious d m ges. (Pic. 6.1).
• Re r mounted t nk c p city: 3,2 l.
• Side mounted t nk c p city: 4 l.
• See p r gr ph 2.3 for the oil consumption of e ch model.
• Top up with fresh nd cle n oil only; use the oil required in
p r gr ph 2.6 or equiv lent.
• The oil must be topped-up with the m chine stopped nd cold.
Do not re se the oil collected by the separator
applied to the p mp drain.
• Apply the s fety requirements indic ted in ch pter “S fety nd
ccident prevention” before topping-up.
Checking the gearbox oil level
• The oil must be topped-up with the m chine stopped nd cold.
• Apply the s fety requirements indic ted in ch pter “S fety nd
ccident prevention” before topping-up.
• The oil level in the ge rbox must re ch the side disch rge hole.
• For the repl cement, dr in the oil from the ge rbox through the
lower disch rge plug nd top-up through the upper filling plug until it
comes out of the side disch rge hole.

• See the t ble in p r gr ph 6.1 for the frequency with which to
repl ce the oil.
Dispose of exha sted oil as provided by c rrent
specification.
• Top up with fresh nd cle n oil only; use the oil required in
p r gr ph 2.6 or equiv lent.
• During the oil repl cement, lso repl ce the disch rge plug
w sher.
L brication control (PNR-PNE73-83 e PNR142)
• Check th t the lubric nt drips properly into the oilers: 60
droplets/min t m ximum speed. For lower speeds: the number of
droplets is directly proportion l.
• Keep the gl ss of the oilers cle n nd in n ccessible position.
If l brication is missing, the decompressor heats
p and the internal components q ickly
deteriorate. Stop the decompressor, check the oil
level and the l brication p mp.
• Tempor ry build-up of lubric nt in the oilers is possible:
- During pressurised service even with regul r dripping,
- With the decompressor stopped.
• This phenomenon:
- Is tr nsient: the oilers empty during the subsequent v cuum
oper tion.
- This does not indic te f ults nd does not jeop rdise
lubric tion of the intern l p rts during pressurised oper tion.
Once p mp is stopped, oilers may be filled p
with oil. This does not mean any p mp fail re
beca se oilers will get empty on next p mp-
vac m mode start.
• During v cuum oper tion, the build-up of oil in the oilers could
indic te insufficient lubric tion. Check:
- Piping: it could be obstructed or crushed.
- Fittings: they could be loosened.
Checking the vanes wear
• Unscrew the v nes we r check-plug on the front fl nge. See Pic.
6.2.
Pic. 6.2
• Turn the sh ft by h nd until v nes ppe r nce.
• V nes usu lly slip on se t bottom due to gr vity. Check their right
entry in the se t.
• Insert Ø 6 mm stick until it touches the rotor nd then m rk like
in Pic. 6.3.
• Turn the rotor slowly until the stick touches the v ne in idle
position in its se t. The v nes slide to the bottom of the se t due to
gr vity: check they re lly do nd m rk g in on the stick.
• Repe t the s me procedure for ll the v nes. If we r exceeds 10
mm: repl ce the v nes s soon s possible.
Pic. 6.3
• Repl ce ll the pump v nes t the s me time.
Replace the vanes when their wear exceeds 10
mm (L – L min): they may break. Replace all
vanes at the same time.
• Repl ce the v nes when their we r exceeds 10 mm (L – L min):
they m y bre k. Repl ce ll v nes t the s me time.
6.2. Extraordinary maintenance
• Except for the c ses described below, extr ordin ry m inten nce
on PNR/E must be c rried out by speci lized personnel only;
otherwise the gu r ntee will be inv lid ted.
• All extr ordin ry m inten nce interventions must be c rried out
when the m chine is cold, stopped nd switched off. Implement the
s fety instructions reported in the “S fety nd ccident prevention”
Ch pter, before performing ny m inten nce oper tion.
Follow the safety prescriptions as described in
Cap. “Safety and accident prevention”.
Replacing the vanes (PNR/PNE 73-83-104-124)
• Remove the v cuum pump from its be ring fr me nd w sh it
before dis ssembling.
• It is suggested to remove the oil t nk on the re r p rt bec use
gener lly the pump’s drive components re fitted on the front fl nge.
