Attention: ca efully apply these p esc iptions.
3.1 Gene al ecommendations
• 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...).
• 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.
• Dur nte il tr sporto del decompressore utilizz re degu te
imbr c ture. Appoggi re il decompressore su punti st bili.
• When tr nsporting the compressor use proper slinging. Store the
compressor in st ble pl ces.
• 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.
• When the pump is running, some p rts m y re ch very high
temper tures ( bove 100°C). Use ll necess ry prec utions to void
cont ct.
• 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.
• 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 sunction line (Mesh 55).
• Do not st rt the m chine if the protection devices provided for
tr nsmissions re removed. Repl ce d m ged p rt.
• 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 powe supply
pa amete s indicated in the technical tables (see
pa . 2.2 - 2.3).
3.2 Intended use
• 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.
• 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.
• Evit re l’ spir zione di m teri li tossici e di g s infi mm bili o
esplosivi poiché i componenti interni possono r ggiungere temper ture
elev te.
• Avoid suction of liquids or solids, they c n seriously d m ge the
pump.
• Do not run the pump over its designed oper ting limits (see p r.

4.1. Checking upon eceipt
• When the goods re delivered, m ke sure th t ll p rts listed on
the delivery note re in perfect condition nd h ve suffered no d m ge
during shipping.
• M ke sure the v cuum pump h s its identific tion pl te. Pumps
without such identific tion re to be considered nonymous nd
potenti lly d ngerous: in such n event, they must not be used,
otherwise the m nuf cturer will be deemed free from ny li bility
wh tsoever.
• Pump must be kept in dry stor ge re . During stor ge, inlet nd
outlet ports must be kept closed.
4.2. Sto ing in the wa ehouse
• If the compressor will not be inst lled inside short time fter
delivery:
- Remove the gu rds from the ports nd spr y film of
protective oil over the inner surf ces of the body, rotors nd
sides. Then tt ch g in the gu rds;
- Store in closed nd dry pl ce. Renew the preserving oil
periodic lly.
• To tempor rily store used pump, follow the instructions below:
- Thoroughly cle n the pump.
- Equip the pump with suit ble nti-corrosion protection.
4.3. Mounting
• 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.
• 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 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.
• 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.
4.4. Vacuum / P essu e line
• See picture 4.2.
Pic. 4.2
• 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 (Fig.
4.1 - pos. 10) 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.
• Over-pressure s fety relief v lve (Pic. 4.2 - pos. 5). It must be
dimensioned to disch rge the entire ir-flow of the pump. The
djustement of this v lve h s to be kept inside 10% of toller nce of the
pump's working pressure nd in ny c se it h s to st y inside the given
v lue of the t nk's work pressure.
• V cuum control v lve h s to be fitted on the suction piping, if the
t nk's ch r cteristics or the v cuum line will need this kind of v cuum-
limiting device.
Pic. 4.3
• For pumps th t re ch, during norm l oper ting, disch rge ir
temper ture close to 150 °C (300°F) - (checked t not more th n 150
mm from the disch rge connection) it is necess ry to use device
(overhe ting limiter) th t will not llow to exceed such temper ture.
Cont ct our Technic l Dep rtment.
• An djust ble curved pipe is inst lled on the outlet of the silencer,
in order to prevent r in from entering nd to en ble positioning (during
inst ll tion) of the output irflow.
• Direct the silencer disch rge output w y from the silencer suction
inlet in order to prevent the input of hot fluids into the injection inlet.
Attention: di ect the silence discha ge output
away f om the silence suction inlet.
4.5 Hyd aulic actuato adjustment
• Extr ordin ry m inten nce oper tions c n require the upper cover
( nd th t of the ctu tor, either m nu l or pneum tic) to be removed.
We recommend ensuring enough sp ce to c rry out such oper tions.
• If the cock blocks or it moves with friction, screw up the cle r nce
regul tion nut (A). Screw up ¼ of turn e ch time. Block the nut rot tion
with the s fety nut.
• The lubric tion points (B) nd the cle r nce regul tion bolt (A)
must be ccessible. See Fig. 4.5.
• Lubric te with gre se every 1000 cycles. Gre se type NLGI 2.
• It is suggested to inst ll 2 one‐w y flow controller between the
hydr ulic switch nd the hydr ulic ctu tor. Set the flow controllers in
order to prevent h rd hitting through the end of stroke. Minimum
commut tion time: 1 second.
• M ximum feed pressure: 30 b r.
• To order sp re p rts see sp re p rts list t the end of this m nu l.
Pic. 4.4
4.6 Pneumatic actuato adjustment
• In the event of 4-w y v lves equipped with pneum tic ctu tor, we
recommend inst lling two one-w y flow regul tors between the
pneum tic “control” nd the pneum tic ctu tor. The following figure
shows schem tic view of possible pneum tic inst ll tion.
Pic. 4.5
• We recommend djusting the two flow regul tors in order for
rot tion to occur without knocks nd with switching time of t le st
one second.
4.7. Pump mounting - d ive connection
A) Ca dan shaft d ive
• Use telescopic c rd n sh fts.
• In order to chieve uniform motion of the driven sh ft, the
following requirements must be met (see Pic. 4.6):
- Equ l working ngle α nd α1 of both couplings;
- The intern l fork joints must be copl n r;
- Both driven nd driving sh fts must be copl n r.
• It is lso recommended working with limited rticul ted joint ngles
(m x 15° t 1000 rpm nd m x 11° t 1100 rpm) nd diseng ging the

5.1. Pump sta ting-up
• Before st rting the equipment check the lubric ting oil level of the
pump.
• 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

Do not otate in the w ong di ection:pump may be
damaged.
• Check which position of the 4-w y integr ted v lve lever llows
v cuum or pressure functioning.
• If the pump h s been in stor ge for long time: inlet. liter of oil in
the pump for n e sy cle ning of intern l p rts.
• 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 vacuum pump is designed to wo k at
maximum speed. Fo longe ope ating we
ecommend the pump be un at wo king speed.
• Prep re dequ tely tr nsmission.
5.2. Ope ating p ecautions
• 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: 150°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

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 vacuum ate has been eached,
we ecommend educing the vacuum pump
speed to its wo king speed.
• Intern l w sh-up is necess ry fter prolonged in ctivity, fter
working in dusty environments or in c se of ccident l suction of
liquids. Such oper tion must be c rried out only on cooled pumps.
1. Disconnect the exh ust silencer, if possible;
2. St rt running the pump t low speed;
3. Suck some w ter ( bout 1-2 litres) through the inlet port;
4. Then suck oil ( bout 1 litre) to complete the w sh-up nd lubric te
intern l components.
In case the exhaust line cannot be disconnected,
d ain the liquids accumulated in the sepa ato of
the exhaust silence .
• 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

Assemble ope ation
• Re ssemble everything g in in the right sequence, bsolutely
voiding to le ve foreign p rts inside the pump. Alw ys ch nge ll the
g skets nd the OR (pos. 5) fter h ving them properly lubric ted nd
lso the se l (pos. 4) if necess ry. Put some gre se in the sp ce
between the be ring (pos. 6) nd the fl nge (pos. 1).
• Re ssemble the fl nge (pos. 1), nd the OR (pos. 5) c refully
inserting the drive sh ft without d m ging the se l (pos. 4).
• Insert the be ring (pos. 6), the compens tion ring (pos. 8) nd the
oil pump’s fl nge (pos. 2).
• Insert correctly the lubric tion pump (pos. 7) in the driving slot nd
refit the fl nge.
• Re ssemble the lubric tion pipes nd fittings.
• Re ssemble the re r protection (pos. 3).
Gene al wa nings
• On direct drive models norm lly it is not necess ry to remove the
front sm ll fl nge. However, if this h s to be done do not forget to
gre se the underne th be ring.
• The front be ring h s been gre sed during pump’s ssembling.
Lubric tion of s id be ring is necess ry fter long working periods only
(for ex mple, norm l dur tion of set of v nes). It is consequentely
suggested to pump c refully new gre se through the lubric tion nipple
in order to void d m ges to the se ls.
• When ch nging the v nes do not forget to c refully cle n ll the
components th t you h ve dism ntled. Cle n the oil filter nd the oil
t nk from the solid sediments. The models PNR142, re provided with
side oil t nk; be c reful to the m ximum tight torque of the oil filter
plug. M ximum torque: 10Nm.
Mounting the hyd aulic d ive
• We recommend the drive coupling be oiled when v nes re being
repl ced.
• However lubric te the drive coupling every 1500 hours.
We ecommend the d ive coupling be oiled eve y
1500 hou s.
• Apply coupling hub to v cuum pump xis respecting the position
m rked during dis ssembly: the gr in must go b ck into the se t on the
rim.
• Mount the coupling nd lubric te intern lly with NLGI 2 Lithium
gre se. Provide n dequ te qu ntity of f t, in order to h ve medium
filling.
• Re ssembly the motor without forcing onto the se ls.
Adjusting the self-lub icating pump
• The utom tic lubric ting pump is djusted by the m nuf cturer
before the shipping.
• If consumption notice bly differs from the indic ted v lue, djust it
s follows:
- Remove the upper protection cover;
- Using screwdriver nd 10 mm wrench, djust the djusting
screw (K). Close the nut nd remount the upper protection cover;
- It is dvis ble to turn the screw of ¼ of turn nd verify the ctu l
consumption.
Pic. 6.7
Do not educe oil consumption below the value
indicated in pa . 2.2 (fo functioning at speeds
diffe ent f om the maximum, flow is p opo tionate
to otating speed).
• ½ turn of the djusting screw c uses v ri tion in the flow of
pproxim tely 40 - 80 g/h, depending on using conditions.
Cleaning of the inside exhaust po t of the pump housing and
the 4-way manifolds
• Frequency: t every ch nging of the v nes.
• How to proceed: dism ntle the m nifold nd remove possible
oilsc les or other foreign p rts.
• The clogging-up of this m nifold nd the exh ust port depends
m inly from he vy duty use of the pump nd c uses n incre se of
temper ture nd non perfect closing of the check v lve. A c reful
cle ning of ll components, including the insides of the housing nd the
non-return check v lve nd it’s se t, is therefore strongly
recommended.
