ATTENZIONE!
AVVERTENZA!
AVVERTENZA!
Prima di avviare la pompa, occorre procedere al rifornimento di olio lubrificante,
poichè la pompa viene fornita scarica.
Togliere i tappi di protezione posti sulle flange di aspirazione e scarico prima
di ogni successiva operazione. L’aria contenuta all’interno della pompa, in
caso di accensione involontaria, può proiettarli contro l’operatore.
Durante l'installazione prestare la massima attenzione che la flangia di
aspirazione sia collegata alla camera da evacuare e che la flangia di scarico
non sia tappata (vedere la figura seguente). La pompa non deve essere usata
come compressore. La massima pressione interna al contenitore dell'olio
non deve superare 1,5 bar (abs). L'inosservanza di queste precauzioni può
causare danni alla macchina ed all'operatore.

ATTENZIONE!
Uso
AVVERTENZA!
Controllare che la tensione di alimentazione corrisponda a quella indicata sul
cartellino del motore.
Collegare la pompa all’alimentazione.
Nel caso di motore trifase, una inversione di polarità provoca l'inversione del
verso di rotazione della pompa, con conseguenti possibili danni di natura
meccanica.
Prima di mettere la pompa in servizio effettivo è necessario, per il
raggiungimento del vuoto limite, far marciare per circa un’ora la
pompa con zavorra aperta allo scopo di eliminare l’umidità nell’olio.
L'accensione della pompa non richiede particolari manovre; è
sufficiente collegarla all’alimentazione elettrica agendo
sull’interruttore bipolare (versione con motore monofase) o
onnipolare (versione con motore trifase).
La pompa è progettata per operare con fluidi neutri o non corrosivi. È
assolutamente vietato l'impiego con sostanze potenzialmente esplosive o
infiammabili.
Lo spegnimento della pompa non richiede particolari manovre; è
sufficiente scollegarla dall’alimentazione elettrica agendo
sull’interruttore bipolare (versione con motore monofase) o
onnipolare (versione con motore trifase).

These vacuum pumps are suitable for pumping non corrosive gases.
The main features are:
all parts in direct contact with the fluid pumped are free of
copper alloys;
all materials are carefully selected to provide extended life;
a high capacity gas ballast device allow to pump condensable
vapors;
all the parts composing the pump are fully replaceable due to the
close machining tolerances and to the centering obtained by
using reference pins;

Technical Description
due to its design features and low number of gaskets, the pump
requires little maintenance, disassembly and reassemble are easy
and require minimal time.
The pump works with force-feed lubrication, provided by an auxiliary
gear-pump driven by the rotor of the vacuum pump itself. This
ensures proper lubrication even when pressures are close to
atmospheric.
The entire pump functional block is immersed in the oil contained in
the casing. The oil guar3antees perfect sealing of the discharge
valves, enters the pump to ensure lubrication and sealing of the parts
inside, facilitates heat dissipation and reduces pump noise.
The pump is equipped with a special anti-suckback device which
automatically isolates the vacuum system when the pump stops. This
avoids rises in pressure or oil flow in the vacuum system while air is
allowed back into the stator chambers.
The air entering the pump after the anti-suckback device has closed
prevents the oil in the casing from filling the stator chambers.
The inner seals are achieved by the lubricating oil, thanks to the close
machining tolerances.
There is only one oil seal on the rotor shaft, the one preventing oil
from seeping out of the pump. This seal acts on a bushing fitted onto
the shaft. Simple replacement of this seal grants the rotor a
practically unlimited life (pumps DS402 1Ph, DS402 3Ph, DS602 1Ph,
DS602 3Ph). On the DS102 1Ph, DS202 1Ph and DS302 1Ph pumps,
this seal acts on a surface-hardened area of the shaft guaranteeing
long rotor life.
The vacuum pumps are connected directly to the electric motor
through a flexible coupling, so that motion is transmitted even in
case of poor alignment.
A fan fitted on the joint and housed in the pump support produces a
forced air flow over the finned surfaces of the casing to avoid oil
overheating.
52/140 Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01(L)
Lubrication
The pump’s lubricating system is force-feed type.
Oil circulation is obtained by means of a gear pump connected to the
rotor shaft.
The oil is drawn through a gauze filter to prevent any foreign bodies
from entering the pump.
Shunt-mounted on the delivery line is a hydraulic piston which,
besides actuating the anti-suckback device (see ANTI-SUCKBACK
DEVICE), also regulates pressure by discharging excess oil flow
directly into the tank.
The required flow of oil under pressure passes through ducts that are
drilled in the walls of the pump and lubricates the bushings and the
inside parts.
Vacuum Seals
A special feature of this pump is the low number of gaskets that are
employed.
Technical Description
Lubrication
5
The seals in the circuit are obtained by means of VITON gaskets.
The careful surface finish of the various parts of the pump means
that vacuum sealing of the functional block is ensured by the film of
oil separating metal surfaces. Sealing of the rotor shaft is guaranteed
by a rotating gasket with dust-guard lip.
The suction flange and duct are sealed by mean of OR gaskets.
Gas Ballast Valve
When the pump sucks in vapors, these condense during compression
and mix with the oil, forming an emulsion (an aqueous vapor, for
example) or a solution (organic solvent vapors, for example).
A number of problems arise from this, such as the impossibility of
obtaining high vacuums, the alteration of the properties of the oil,
could cause scaling on parts of the pump.
Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01(L) 53/140
Technical Description
5
Anti-Suckback Device
To avoid this, during compression at the second stage, atmospheric
air is let into the pump through an adjustable valve, or “gas ballast
valve”, located at the top of the pump.
In this way, the discharge valve of the second stage opens through
the effect of the atmospheric air before the partial pressure of the
vapor reaches saturation point, thus preventing condensation from
occurring. The vapors are expelled mixed with air.
Anti-Suckback Device
The pump is equipped with a special anti-suckback device to avoid
air pressure rises and/or oil backflow towards the evacuated vessel
when the pump is switched off. This device has a shutter which
automatically closes the suction duct.
In this way the pump and vacuum system are completely isolated
from each other and air can enter the pump without any risk for the
vacuum produced in the system.
The device includes some special features, namely:
drive obtained avoiding any form of contamination of the inlet
duct by fluids (oil and/or air) used to command the shutter.
Thanks to this, when the pump is started again, the pumpdown to
vacuum conditions is extremely fast as these contaminants are
not present and no degassing is therefore required;
suction flange maintained closed even when the pump is idle, so
that pollutants cannot enter from the environment and no oil can
overflow from the pump.

Transport and Installation
Setting the pump in position should be performed as follows:
Pump laid on the ground. There are no special instructions for
this type of installation, except that the floor should be as flat as
possible and suited to bear the weight of the pump (it should
ideally be a concrete floor) and of any accessories mounted on it.
Note that the pump is stable on its base plate and it should not be
necessary to anchor it to the floor with bolts and screws; also
vibrations to and from the pump are greatly reduced by the use
of rubber feet.
Pump off the ground. In this case, the user must design a suitable
support structure, remembering the following points:
the plane supporting the pump must be perfectly horizontal;
the structure should be adequately rigid;
the relevant safety precautions should be applied.
Note also that the pump should be attached to the supporting
structure after replacing the rubber feet with special antivibration feet, which should be screwed to the pump base and to
the supporting plane.
After taking the pump out of its packing case, you are advised to
make the following checks:
a Ensure that the pump has not suffered any damage during
shipping.
b Check that the guards are mounted correctly (side plates, refs. 11

NOTE
NOTE
NOTE
For guaranteed reliable sealing, use an OR gasket in Perbunan or Viton.
The inlet duct is equipped with a sieve filter preventing solid
particles from entering and damaging the pump.
When the gases to be pumped out contain dust, it is advisable to insert a dust
filter before the inlet flange.
When the gases to be pumped out contain large quantities of vapor, it is
advisable to include a condense separator before the inlet flange.
To make best use of the pump’s capacity, use only short, straight
piping, with a diameter not smaller than that of the inlet flange.
If rigid piping is used, it is good practice to use a flexible joint in order to avoid
undue forcing of the connection on the pump.
The exhaust duct must be connected to a pipe that will take away the
pumped out gases.

Starting and Running the Pump
NOTE
CAUTION!
Application of an oil trap filter is necessary to avoid pollution of the surrounding
atmosphere by the oil present in the exhaust duct during pump operation.
Never block the pump exhaust line. This would cause overpressure in the casing
with the risk of breaking the glass window of the level indicator and/or expelling
the oil seal gasket.
Starting and Running the Pump
Before being put into service, in order to reach maximum vacuum,
the pump must be left running for about an hour with the gas ballast
valve open. This will eliminate any humidity from the oil.
WARNING!
The pump is designed for operation with neutral or non-corrosive fluids. It is
absolutely forbidden to use potentially explosive or flammable substances.
NOTE
74/140 Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01(L)
If the pump is started with cold oil, initially more than normal noise will be
heard; this will last for a few minutes only until the oil reaches its working
temperature.
There are no special instructions for normal operation of the pump,
which is delivered to you after completion of a running-in cycle in the
factory. The maintenance operations for a pump in working
condition may be found on the Scheduled Maintenance Cards.
Technical Description
Stopping the Pump
If the pump is sucking in environments with liquids or vapors, it is
important to leave it to run with the gas ballast open so as to avoid
condensation of the vapors and contamination of the lubricating oil
as a result. When there is no danger of the oil being contaminated,
the gas ballast valve should be closed to reduce the pump’s power
absorption.
The gas ballast valve will prove useful in the cold season when, due
to the lower room temperatures, it takes longer for the pump to reach
rated temperature when switched on. Compression of the air forced
in by the gas ballast valve develops heat, which in turn increases
temperature of the oil faster.
5
NOTE
NOTE
If gases without vapors are sucked in, you are advised to open the gas ballast
device from time to time in order to eliminate the traces of humidity they
contain.
For repetitive work cycles, with brief time intervals in between, it is better not to
stop the pump.
Stopping the Pump
There are no special procedures for switching the pump off; it needs
only to be disconnected from the electric power by means of the
bipolar switch (version with single-phase motor - see section
MODELS WITH SINGLE-PHASE UNIVERSAL MOTORS) or of the
multipolar switch (version with three-phase motor - see section
MODELS WITH THREE-PHASE UNIVERSAL MOTORS).
When the pump is stopped, the anti-suckback device makes it
possible to maintain vacuum in the vessel connected on the inlet
flange of the pump.

Safety Rules
If the pump is expected to be stopped for a lengthy period, or in any
case if it has pumped in large amounts of vapors, it is good practice
to run it with the gas ballast open and the inlet line closed for a few
minutes before switching off in order to limit the risk of corrosion or
scaling due to pollution of the oil by condensed vapors.
Safety Rules
Personnel responsible for pump operation and maintenance must be
well-trained and must be aware of the accident prevention rules.
The accident prevention precautions contained in this section must
be respected at all times during operation and maintenance of the
pump to avoid damage to operators and to the pump.
These precautions are provided in the form of WARNING and
CAUTION notes.
WARNING!
CAUTION!
Operating procedures, technical information and precautions which, if not
respected and/or implemented correctly may cause body harm to operators.

°C.
f Failure to provide the pump with an earth connection may cause
serious damage to operators. Always ensure that there is an earth
connection and that it complies with the standards.
g When cleaning the pump and its component parts, avoid the use
of flammable or toxic solvents, such as benzin, benzol, ether or
alcohol. The recommendation is to use a soap and water solution,
preferably in ultrasound washing machines, taking care to dry all
the cleaned parts at temperatures under 100 °C in order to
eliminate residual moisture.
h Prolonged overloads or breakdowns may cause the electric motor
to overheat, and to release noxious smoke; remove the power
immediately as a precaution and do not approach the pump at
least until you have provided ventilation to drive out the smoke.
Take care not to breathe in the fumes remaining inside the pump
in the course of repair work.
i In case of fire, do not throw water on the pump. Switch the
power off and use CO
extinguishers.

surfaces. Slight scratches and abrasions may be eliminated with
very fine emery paper or by a little light grinding.
x Before putting a group together, always spread a little oil over
inner parts and mating surfaces. Replace all seals with original
spare parts before reassembling components.

NOTE
CAUTION!
The frequency with which repairs are performed depends on the process and
presence of substances that shorten pump life (dust, abrasives, solvents, water,
chemically aggressive substances).
The pump must be cleaned at regular intervals of time.
Do not clean with Alcohol the plastic or rubber components of the pump.
Use only the strictly necessary amount of lubricant; an excess of
lubricating oil, like when there is none, may sometimes compromise
proper operation of the pump.
Only the recommended lubricants, or lubricating oils with similar
characteristics and known and experimented quality, should be used.
Oil changes must be made with the oil at a sufficiently high
temperature, after leaving the pump to cool for a few minutes
following operation.
The drain and filler plugs must not be left open any longer than is
strictly necessary.
When performing maintenance, look out for all signals that may
precede a breakdown, in particular:
traces of corrosion;
oil leaks;

slack joints or couplings.
Maintenance technicians must:
be aware of all applicable national directives concerning accident
prevention during work on motor-driven pumps and should
know how to apply them;
have read and understood all the sections on “Safety Rules";
be familiar with the essential design features and operation of the
pump;
know how to use and consult the pump documentation;
be concerned about proper operation of the pump;
make a note of any irregularities in operation of the pump and
take the necessary action, where appropriate.
Use original spare parts wherever possible and repair a broken part
as best as possible on site or send it back to the manufacturer for
repairs.
For all problems arising, or to order spare parts, refer to our service
department.

Lubricants
It will be readily understood how important adequate lubrication is
to high technology pumps like the Agilent vacuum pumps. Correct
use of appropriate lubricants makes a significant contribution to
achieving best performance and warding off defects.
When handling lubricants, the following sanitary protection
measures should be observed at all times:
80/140 Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01(L)

Lubricants
Avoid prolonged, excessive or repeated contact of the skin with
products for lubrication, and also avoid directly inhaling the
fumes or vapors of such products.
Protect the skin by wearing appropriate clothes and equipment
(e.g. special suits, glasses or, where permitted by the safety
regulations, gloves) or by applying a special protective product.
Clean the skin carefully after contact with the lubricants by
washing freely with water and soap.
Apply a skin cream after washing.
Take off and change clothes or shoes on which oil has been
spilled.
Never put rags dripping with oil into the pockets of your clothes.
When disposing of waste lubricants, observe the following
environment protection regulations:
The lubricants risk contaminating the water and the ground!
Therefore never pour lubricating products on to the ground, into
water or in the sewage system. All violations of these rules are
liable to persecution as provided for by law. When using
lubricants always keep an oil can nearby.
Take care in draining off waste oils. In disposal of these products
respect all regulations in force concerning waste oil disposal.
The recommended lubricating oil is the Agilent Rotary Vane Fluid
DS19 Type. The Rotary Vane Fluid DS19 Type is a general purpose
mechanical pump fluid specifically engineered to provide superior
performance in high speed direct drive mechanical pumps.
These precisely distilled fluids (100 % solvent refined neutral
paraffinic oil) deliver lower base pressure capability, faster pumpdown cycles, and reduced maintenance requirements on both the
pump and the fluid.
It is absolutely necessary to continue using the lubricants initially
used to fill the tank. If this is not possible for organizational or
business reasons, use only products with the same characteristics as
the previous oils.

Lubricants
Only use of lubricants of suitable quality will guarantee safe
operation of the pumps.
CAUTION!
CAUTION!
Mineral oils and the PFPE oil are incompatible. To change from one type to
another, the pump must be stripped down completely and all parts washed
carefully to eliminate all oil residues.
If you expect to have to use other lubricants, first find out if the two
products are compatible. In cases of doubt, the lubricant used up to
that time must be flushed out by way of a pump flushing procedure.
To avoid the risk of contaminating the oil, absolute cleanliness of the pump and
surrounding area must be ensured during the lubrication procedures.

If you have to perform maintenance on the pump after a considerable time in
operation, leave it to cool as temperature of the outer surface may be in
excess of 60 °C.
1. Remove the filter (26) from the inlet flange (28).
2. Clean the filter using an aqueous solution and dry with hot air.
3. Put the filter back in place.
The filter element is designed to prevent solid particles in the air from entering
the inside of the pump and if it is not working properly, serious damage could be
caused the pump’s inner parts. In such cases, it may be worthwhile installing a
large surface area filter in the pump's suction line to improve effectiveness and
reduce maintenance frequency.
If the pump sucks in gases and vapors that contain large quantities of solid
particles, the filter must be checked and cleaned more often than indicated here.
