AVVERTENZA!
Allo scopo di garantire che la pressione interna al contenitore dell'olio non
superi mai il valore massimo ammissibile di 1.7 bar (abs), sulla pompa è
installato un dispositivo di sicurezza indicato dalla freccia rossa nella figura
sottostante. Trattandosi di dispositivo di sicurezza, questo tappo non va in
alcun modo sostituito, danneggiato o manomesso. E’ ammessa la sua
momentanea rimozione (tramite svitamento) per consentire la carica
dell’olio nella pompa quando necessario. E’ responsabilità dell’utente
riavvitare il dispositivo nella sua posizione originaria dopo l’avvenuta carica
dell’olio e prima dell’avvio della pompa.
L'inosservanza di queste precauzioni può causare danni alla macchina ed
all'operatore.
Nel caso in cui la pressione del contenitore dell’olio superi i valori limite
ammessi (ad esempio per scarico ostruito) una miscela di gas aspirati e olio
fuoriuscirà dal tappo di sicurezza. Questa fuoriuscita continuerà fino allo
spegnimento della pompa e/o alla rimozione della causa di sovrappressione
(ad esempio rimozione dell’ostruzione dello scarico).

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

WARNUNG!
Zur Gewährleistung, dass der Innendruck im Ölbehälter den zulässigen
Höchstwert von 1.7 bar (abs) nicht übersteigt, ist in der Pumpe eine
Sicherheitsvorrichtung installiert (siehe roter Pfeil im Bild). Es handelt sich
um eine Sicherheitsvorrichtung, somit darf der Verschluss auf keinen Fall
ersetzt, beschädigt oder manipuliert werden. Eine vorübergehende
Entfernung (durch Abschrauben) ist möglich, damit das Öl bei Bedarf
nachgefüllt werden kann. Der Anwender muss die Vorrichtung wieder in
ihren Platz einschrauben, nachdem das Öl eingefüllt wurde und bevor die
Pumpe wieder gestartet wird.
Die Nichtbeachtung dieser Vorsichtsmaßnahmen kann der Maschine und
dem Bediener Schaden zufügen.
Falls der Druck in dem Ölbehälter die zugelassenen Werte überschreitet
(zum Beispiel aufgrund eines verstopften Auslasses), wird eine Mischung
aus angesaugtem Gas und Öl aus dem Sicherheitsverschluss treten. Dieses
Austreten erfolgt bis zum Abschalten der Pumpe und/oder Beseitigung des
Grunds für den Überdruck (zum Beispiel Entfernung der Verstopfung am
Auslass).

AVERTISSEMENT!
Afin de garantir que la pression interne du réservoir d'huile ne dépasse
jamais la valeur maximum admissible de 1,7 bars (abs), un dispositif de
sécurité a été installé (indiqué par la flèche rouge ci-dessous). S'agissant
d'un dispositif de sécurité, ce bouchon ne doit en aucun cas être remplacé,
endommagé ou modifié. Il est possible de le retirer momentanément (en le
dévissant) pour permettre le remplissage d'huile dans la pompe lorsque cela
s'avère nécessaire. L'utilisateur est tenu de revisser le dispositif dans sa
position initiale après avoir rempli le réservoir d'huile de la pompe et avant
de la démarrer.
Tout manquement à ces consignes comporte des risques pour la machine et
l'opérateur.
Au cas où la pression du réservoir d'huile dépasserait les valeurs limites
admises (ex. suite à colmatage de l'évacuation) un mélange de gaz aspirés
et d'huile sortira du bouchon de sécurité. Cette décharge de pression
continuera jusqu'à l'arrêt de la pompe ou l'élimination de la cause de la
surpression (élimination du colmatage de l'évacuation).

WARNING!
A safety device (indicated by the red arrow in the figure below) is installed
on the pump to guarantee that the pressure inside the oil vessel never
exceeds the maximum permitted value of 1.7 bar (abs). This is a safety
device and for this reason the cap must not be replaced, damaged or
tampered with. Temporary removal (by unscrewing) is allowed to fill oil into
the pump when needed. Users are responsible for screwing the device back
in its original position after filling and before starting the pump.
Failure to respect these precautions may cause damage to the machine and
injury to the operator.
A mixture of intake gas and oil will issue from the safety cap if the pressure
in the oil vessel exceeds the allowed limit values (e.g. obstructed exhaust).
The flow will continue until the pump is stopped and/or the cause of
overpressure is removed (e.g. obstruction is removed from exhaust).

vapors;
Dual Stage Rotary Vane Pumps User Manual / 87-900-937-01 (R) 75/168
5 Technical Description
Technical Description
all the parts composing the pump are fully replaceable due to the
close machining tolerances and to the centering obtained by
using reference pins;
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 guarantees 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.
76/168 Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01 (R)
Lubrication
5
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
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.

5 Technical Description
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.

Safety Precautions
Always carry the pump by means of the handles provided.
The pump must be set in position taking the upmost care in order
to avoid accidental falls.
Technical Description
WARNING!
In case of a need to handle the pump after a period of operation, it must be
left to cool first as the external surface temperature may be in excess of
60 °C.
Transport and Installation
The pumps are shipped to the customer inside cardboard boxes.
Total weight of the pack, including the pump, is between 30 Kg. and
40 Kg. according to the different pump models.
The case must be handled with care, using appropriate lifting
equipment.
CAUTION!
When moving the case, ensure that it is securely bound to the lifting equipment
and that the equipment is strong enough to support the weight.
The pump’s working environment is a traditional industrial
environment. Naturally sites with corrosive vapors or excessive heat
are best avoided.
Room temperature should ideally be between 12 °C and 40 °C.
If the temperature is not inside this range, consult Agilent technical
service for the changes required.
Dual Stage Rotary Vane Pumps User Manual / 87-900-937-01 (R) 89/168
5 Technical Description
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.
90/168 Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01 (R)
After taking the pump out of its packing case, you are advised to
make the following checks:
Ensure that the pump has not suffered any damage during shipping.
Check that the guards are mounted correctly (side plates, refs. 11 and
81 in fig. View of the pump) and that there are no uncovered or loose
parts.

body. Should it rotate in the opposite direction, invert the connection of any two
phases on the motor terminals.

CAUTION!
In order to easily identify which disconnecting device related is used for the DS
Pump, the Circuit Breaker must to be marked to Marked.
Only electrically trained staff may install the 3Ph models and may change the
connection from STAR to DELTA or from DELTA to STAR.
Before starting the pump, give a short activation to the power switch,
in order to check that the motor turns in the direction indicated by
the arrow on the motor body. Should it rotate in the opposite
direction, invert the connection of any two phases on the motor
terminals.
One of the most effective method to verify the rotational way of the
motor, it is to start the pump with a sheet of paper on the pump inlet.
If the paper is sucked by the pump then the motor runs in the right
way.
Connections to the Inlet and Exhaust Flanges
Remove the protective caps from both flanges. Remove protective cap
from inlet flange. Remove metallic cap and rubber membrane from
exhaust flange as explained in the Installation chapter. Connect the
system to be evacuated to the inlet flange, using a centering ring with
OR and a locking collar.
NOTE
98/168 Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01 (R)
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.

NOTE
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.
atmosphere by the oil present in the exhaust duct during pump operation.
CAUTION!
Never block the pump exhaust line. This would cause overpressure in the casing
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.

Starting and Running the Pump
WARNING!
NOTE
The pump is designed for operation with neutral or non-corrosive fluids. It is
absolutely forbidden to use potentially explosive or flammable substances.
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.
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.
NOTE
100/168 Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01 (R)
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.
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.
