Technical Description
The main features are:
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;
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 antisuckback device.
There is one oil seal on the rotor shaft, preventing oil from seeping
out of the pump. This seal acts on a bushing fitted onto the shaft.
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.

Technical Information

Lubrication
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 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
The seals in the circuit are obtained by means of VITON gaskets.
Sealing of the rotor shaft is guaranteed by a rotating gasket with
dustguard 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.
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.

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 con-dense 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
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!
NOTE
The pump is designed for operation with neutral or non-corrosive fluids. It is
absolutely forbidden to use potentially explosive or flammable sub-stances.
There are no special instructions for normal operation of the pump,
which is delivered to you after completion of a runningin cycle in the
factory.
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.
If gases without vapors are sucked in, you are ad-vised to open the gas ballast
device from time to time in order to eliminate the traces of humidity they
contain.
NOTE
60/74 DS 42 Dual Stage Rotary Vane Pump User Manual / 87-900-977-01 (D)
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.
When the pump is stopped, the anti-suckback de-vice makes it
possible to maintain vacuum in the vessel connected on the inlet
flange of the pump.
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

Lubricants
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:
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 lubricat-ing 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 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
DS31 Type. The Rotary Vane Fluid DS31 Type is a general purpose
mechanical pump fluid specifically engineered to provide superior
performance in high speed direct drive mechanical pumps.

Lubricants
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. 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.
