• Use adequate cl thing (av id ties, l se sleeves, necklaces and
s n) and suitable pr tecti n equipments (gl ves, pr tecti n glasses,
b ts...).
• T prevent err rs and hazard us situati ns, establish what each
perat r is resp nsible f r in the different maintenance perati ns.
• When transp rting the pump, use pr per slinging. St re the pump
in stable places.
• Make sure that all the parts f the unit are idle and c l, bef re
perf rming any maintenance perati n.
• Bef re each maintenance perati n, st p the pump and rest re
the atm spheric pressure.
• When the pump is running, s me parts may reach very high
temperatures (ab ve 100°C). Use all necessary precauti ns t av id
c ntact.
• Operat rs w rking nearby must av id pr l nged exp sure t the
n ise emitted by the aspirat r, if n t equipped with the pr per ear-
pr tecti n devices.
• Av id accidental sucti n f s lids: s lids may be pr jected at high
speed thr ugh the exhaust manif ld and cause injures. A filter must be
m unted n the suncti n line.
• D n t start the machine if the pr tecti n devices pr vided f r
transmissi ns are rem ved. Replace damaged parts.
• Pressure relief valve: p int the air flux away fr m the perat rs.
• D n t use the aspirat r ver its designed limits: the machine may
be damage and the perat r may be injured.
D n t exceed the p wer supply parameters
indicated in the technical tables (see par. 2.4).
3.2 Intended use
• The vacuum pumps RV are designed t c nvey filtered air int
systems f r the vacuum pr ducti n (example: systems f r the sucti n
f p wders r liquid wastes). Any ther usage shall be c nsidered
impr per.
• D n t sack t xic substances and inflammable r expl sive
gasses, since the internal c mp nents f the pump may reach high
temperatures.
• Liquids r s lids infiltrati ns can seri usly damage the pump.
• D n t run the pump ver its designed perating limits (see par.

4.1 Checking up n receipt
• When the g ds are delivered, make sure that all parts in perfect
c nditi n and have suffered n damage during shipping.
• Make sure the vacuum pump has its identificati n plate affixed n
the fr nt c ver. Pumps with ut such identificati n are t be c nsidered
an nym us and p tentially danger us: in such an event, they must n t
be used, therwise the manufacturer will be deemed free fr m any
liability whats ever.
• Pump must be kept in a dry st rage area. During st rage, inlet and
utlet p rts must be kept cl sed.
4.2 St ring in the wareh use
• If the pump will n t be installed inside a sh rt time after delivery:
- Rem ve the guards fr m the p rts and spray a film f
pr tective il ver the inner surfaces f the b dy, r t rs and
sides. Then attach again the guards;
- St re in a cl sed and dry place. Renew the preserving il
peri dically.
• T temp rarily st re a used pump, f ll w the instructi ns bel w:
- Th r ughly clean the pump.
- Equip the pump with suitable anti-c rr si n pr tecti n.
4.3 M unting
• The m unted aspirat r must be accessible f r maintenance and
firmly fixed n a frame r angled base with a 3° max inclinati n n X
and Y axes (see Fig. 4.1). The structure must be fit t av id flexi ns r
vibrati ns.
• Pr vide en ugh space f r air ventilati n and disp sal f heat when
pump is running. See Fig. 4.2 and 4.3 f r indicati n f the distance t
be respected.

• Pr vide the necessary space t reach all p ints f lubricati n
c ntr l ( il level), and the il tank filler cap, the lever f the 4-way
switch, vanes inspecti n p rts.
• The il tank is m unted n the sucti n side f the h using. Thus,
the r tary directi n determines the pump verall dimensi ns. See als
paragraph 2.1.

4.4 Vacuum - pressure line
Pic. 4.5
• See figure 4.5.
• In rder t av id the sucti n f liquids, a primary fl w shut ff valve
(P s. 1) and a sec ndary shut ff (P s. 2) are t be m unted n the
sucti n line. If necessary, als apply a sucti n filter (P s. 3) t prevent
s lids fr m entering.
• The silencer (P s. 4) applied t the pump exhaust - besides
reducing the n ise level - is designed t separate the il mist expelled
fr m the pump utlet p rt. The separat r must be easily drained fr m
il and c ndensate accumulated at regular intervals.
• The diameter f the vacuum r pressure line pipes must be
pr perly dimensi ned t the pump fl w and, in any case, it must be
larger than the diameter f the p rts.
• The pipes weight r their dilatati ns must n t s licit the pump
h using. Use high temperature resistant rubber c nnecti ns.
• Bef re m unting, rem ve the p rt pr tecti ns. All pipes and line
c mp nents must be clean.
• Av id restricti ns and tight curves as much as p ssible, if n t
strictly necessary.
• Exhaust pipe can reach high temperatures. Hence, they must be
pr perly is lated.
• An ver-pressure safety relief valve (P s. 5) sh uld be m unted in
rder t prevent the verl ading f the vacuum pump. M unt the valve
near the pump with ut applying any gate valves n the line.
• A vacuum relief valve (P s. 6) sh uld be applied t limit the
maximum vacuum rate at 80% in rder t prevent the pump running at
c ntinu us duty fr m verheating.
• Venting shutter (P s. 9): it is als useful t c l d wn the
verheated pumps as well as f r their internal wash-up. Direct the air
fl w away fr m the perat rs.
• Therm stat (P s. 8): it must be installed at maximum 150 mm fr m
the exhaust p rt. The sensitive element must reach the pipe centre.
Safety therm stat n manif ld is supplied n request.
4.5 Hydraulic actuat r adjustment
• Extra rdinary maintenance perati ns can require the upper c ver
(and that f the actuat r, either manual r pneumatic) t be rem ved.
We rec mmend ensuring en ugh space t carry ut such perati ns.
• If the c ck bl cks r it m ves with fricti n, screw up the clearance
regulati n nut (A). Screw up ¼ f turn each time. Bl ck the nut r tati n
with the safety nut.
• The lubricati n p ints (B) and the clearance regulati n b lt (A)
must be accessible. See Fig. 4.6.
• Lubricate with grease every 1000 cycles. Grease type NLGI 2.
• It is suggested t install 2 ne‐way fl w c ntr ller between the
hydraulic switch and the hydraulic actuat r. Set the fl w c ntr llers in
rder t prevent hard hitting thr ugh the end f str ke. Minimum
c mmutati n time: 1 sec nd.
• Maximum feed pressure: 30 bar.
• T rder spare parts see spare parts list at the end f this manual.
Pic. 4.6
4.6 Pneumatic actuat r adjustment
• In the event f 4-way valves equipped with pneumatic actuat r, we
rec mmend installing tw ne-way fl w regulat rs between the
pneumatic “c ntr l” and the pneumatic actuat r. The f ll wing figure
sh ws a schematic view f a p ssible pneumatic installati n.
• We rec mmend adjusting the tw fl w regulat rs in rder f r

4.7 Pump m unting - Drive c nnecti n
A) Cardan shaft drive
• Use telesc pic cardan shafts.
Pic. 4.8
• In rder t achieve a unif rm m ti n f the driven shaft, the
f ll wing requirements must be met (see Pic. 4.8):
- Equal w rking angle α and α1 f b th c uplings.
- The internal f rk j ints must be c planar.
- B th driven and driving shafts must be c planar.
• It is als rec mmended w rking with limited articulated j int angles
(max 15° at 1000 rpm and max 11° at 1300 rpm) and disengaging the
transmissi n f r th se perati ns requiring great angles (steering r
lifting).
F ll w the r tati n directi n as indicated n the
pump fr nt c nvey r pr tecti n. F ll w the
instructi ns f the cardan shaft’s manufacturer.
B) Belt drive
Pic. 4.9
• Install a suitable pulley n the sm th shaft as cl se as p ssible
t the pump: 50 mm. Taper l ck pulley are suggested.
• Apply an adequate belt tensi n (see manufacturer’s data). See list
bel ve (T. Max).
• D n t use diven r driving pulleys with a pitch diameter inferi r t
160 mm. Small pulleys require a high belt tensi n, which may cause
premature wear t the bearing r transmissi n damages.
• Let the air circulate freely t c l d wn the pump. Pr vide
pr tecti ns, which ensure adequate ventilati n.
• A limited speed rati will extend the belts life and reduce stress n
the shafts. When p ssible prefer:
- Pulleys with a pitch diameter bigger than the ne indicated,
Dp=180mm;
- Engines r p wer take- ffs with a speed similar t the ne f the
pump.

- T start running the pump again nly when temperature at
exhaust is bel w acceptable values.
• D n t perate the pump with ut lubricati n: it may cause quick
wear and p ssible breakd wn f vanes.
• D n t start running the pump under l ad: that causes stress t the
drive system and the hydraulic m t r.
• Check r tati n speed. The vacuum pump must:
- never exceed the maximum speed: it may cause verheating;
- never run bel w the minimum speed: this may cause an
an mal us wear f the h using.
• D n t accidentally perate the pump in the wr ng directi n: it may
break the vanes.
• D n t c nvey the exceeding delivery utlet t wards the sucti n
p rt, therwise it will sack warm gas.
• In vehicles d n t direct c mpress r’s discharge t the intake f
the engine.
• C ntr l the air fl w by adjusting the r tati n speed: d n t use the
pressure relief valve t discharge the exceeding fl w.
• Internal wash-up is necessary after pr l nged inactivity, after
w rking in dusty envir nments r in case f accidental sucti n f
liquids.
Such perati n must be carried ut nly n c led pumps.
1. Disc nnect the exhaust silencer, if p ssible;
2. Start running the pump at l w speed (500 rpm circa) and l w
vacuum (20-30% max);
3. Suck s me water (ab ut 1-2 litres) thr ugh the inlet p rt;
Then suck il (ab ut 1 litre) t c mplete the wash-up and lubricate
internal c mp nents.
In case the exhaust line cann t be disc nnected,
drain the liquids accumulated in the separat r f
the exhaust silencer.
• Once the needed vacuum rate has been reached, we rec mmend
reducing the vacuum pump speed t its w rking speed (see par. 2.6):
this all ws keeping the achieved vacuum/pressure rate c nstant. The
pump speed can als be reduced t values l wer than the w rking
speed during the tank discharging phase (with the 4-way valve in
pressure m de) with ut increasing the draining time.
• Thus, exhaust temperature is reduced, vane durability is increased
and b th il c nsumpti n and p wer abs rpti n are reduced.
Once the needed vacuum rate has been reached,
we rec mmend reducing the vacuum pump
speed t its w rking speed.
6.1 Ordinary maintenance
• Installati n and maintenance must be perated nly by qualified pers nnel wearing the pr per cl thes and the necessary t ls as well as

Checking lubrificati n
• Check the c rrect perati n f the system / lubricati n circuit.
If the pump is running with ut lubricati n, the
internal c mp nents may quickly damaged due t
verheating. St p the vacuum pump and check the
il level and the lubricating pump.
Checking the rear m unted il tank level
• D n t run the pump with il level under the minimum level: that may
lead t dry functi ning and cause seri us damages. See Fig. 6.1.
Pic. 6.1
• Tank capacity: 4l.
• Use pure fresh il.
D n t re-use the exhausted il gathered n the
b tt m f the exhaust silencer.
Checking the vanes wear
• Unscrew the vanes wear check-plug n the fr nt flange. See Fig.
6.2.
• Turn the shaft by hand until vanes appearance.
• Vanes usually slip n seat b tt m due t gravity. Check their right
entry in the seat.
Pic. 6.2
• Insert a Ø 5 mm stick until it t uches the r t r and then mark (see
Fig. 6.3).
• Turn the r t r sl wly until the stick t uches the vane in idle
p siti n in its seat. The vanes slide t the b tt m f the seat due t
gravity: check they really d and mark again n the stick.
• Repeat the same pr cedure f r all the vanes. If wear exceeds 10
mm: replace the vanes as s n as p ssible.
• Maximum acceptable wear: 12 mm. Immediately replace: vanes
are likely t break d wn.
• 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.
