Section I  
Technical Description 
The MS40+ Single Stage Rotary Vane Pumps are rotary vane pumps 
oil sealed, driven by a three-phase electric motor. 
Figure 3  
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; 
 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 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. 
5 
Technical Information 
Vacuum Seals 
52/90 MS40+ Single Stage Rotary Vane Pumps User Manual / 87-901-008-01 (E) 
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. 
Vacuum Seals 
A special feature of this pump is the low number of gaskets that are 
employed.  
The seals in the circuit are obtained by means of VITON gaskets.  
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. 
Anti-Suckback Device 
The pump is equipped with a special anti-suckback device to avoid 
air pressure rises and/or oil back-flow 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). 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 degas-sing is 
therefore required.

Safety Precautions 
 Always carry the pump by means of the ring-bolt provided. 
 The pump must be set in position taking the upmost care in order 
to avoid accidental falls. 
WARNING! 
In case of a need to handle the pump after a pe-riod 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 about 35 Kg. 
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 equip-ment 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

Technical Information 
Transport and Installation 
56/90  MS40+ Single Stage Rotary Vane Pumps User Manual / 87-901-008-01 (E) 
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 
pos-sible 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, re-membering 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 anti-vibration 
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 there are no uncovered or loose parts. 
Preliminary Operations 
Before starting the pump, check for oil level. 
CAUTION!  Oil must be poured into the casing through the special threaded plughole and 
NOT through the suction line. 
WARNING! 
Take out the protective caps on the suction and exhaust flanges before doing 
anything else. In the event of an accidental start-up, the air inside the pump 
could violently expel the protective caps and harm the operator.

Section II  
Connection to the Electric Supply 
CAUTION! 
It is recommended to connect the pump to the power supply through a dedicated 
safety switch on the main electrical panel of the installation, or in proximity of 
the power supply connection point. 
Connections to the Inlet and Exhaust Flanges 
Remove the protective caps from both flanges. Connect the system to 
be evacuated to the inlet flange, using a centering ring with OR and a 
locking collar. 
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. 
NOTE When the gases to be pumped out contain dust, it is advisable to insert a dust 
filter before the inlet flange. 
NOTE 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.

Technical Information 
Connections to the Inlet and Exhaust Flanges 
58/90  MS40+ Single Stage Rotary Vane Pumps User Manual / 87-901-008-01 (E) 
NOTE 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. 
NOTE An internal oil mist eliminator avoids 
pollution of the surrounding 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 
with the risk of breaking the oil tank.

l  Do not replace the oil immediately after stopping the machine as the oil may still be at 
  high temperature. 
m  Perform repairs in clean and, where possible, dustfree areas. Protect all the clearances of 
  connection points with suitable plastic caps and cover the machined surface areas of all 
  parts stripped down until they are put back on the pump again.

Caution Notes 
a  Before putting the pump back into operation after a breakdown,  inspect it and check 
  carefully for any other signs of damage. 
b  Use only tools that are in perfect working order and specially designed for the job; use of 
  inappropriate or ineffective tools may cause serious damage. 
c  Perform repairs in clean and, where possible, dust-free areas. Protect all the clearances 
  of connection points with suitable plastic caps and cover the machined surface areas of 
  all parts stripped down until they are put back on the pump again. 
d  Always check the lubricant and that it is properly distributed through the pump; 
  inadequate lubrication may damage the pump seriously. 
e  Give the parts some form of marking as you strip them down to ensure that you 
  reassemble them again in the proper order. 
f  Check that there are no scratches or grooves on the machined shafts, in their seats 
  inside the pump or on machine-ground surfaces. Slight scratches and abrasions may be 
  eliminated with very fine emery paper or by a little light grinding. 
g 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.

Maintenance Actions 
Maintenance may be seen as the totality of all scheduled and 
unscheduled maintenance work. 
 SCHEDULED MAINTENANCE: Maintaining the nominal state of 
operation. 
Tab. 2  
Oil level checking  Daily (before every starting) 
Oil change 
8.000 hours (light applications) 
Exhaust filter replacement  If oil mist at exhaust or yearly 
Anti such-back valve checking  6 months 
Fan cover cleaning  6 months 
NOTE The scheduled maintenance is supported by an automatic timer provided by the 
electronic controller. After 8000 h of operation the status led starts blink-ing 
(400 ms period) orange. The led blinking highlights that is necessary to change 
the oil. To switch off the alarm it’s necessary to use the serial interface (see 
window list in the following pages). It is possible to read the Scheduled 
Maintenance timer by using the serial interface. 
 UNSCHEDULED MAINTENANCE: Restoring the nominal state 
of operation. 
NOTE 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. 
CAUTION!  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.  
Technical Information 
Maintenance Actions 
5 
MS40+ Single Stage Rotary Vane Pumps User Manual / 87-901-008-01 (E) 65/90 
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.

Oil and Filter Cartridge Replacement Procedures 
Oil Change Procedure 
1. Place a tank for waste oil under the oil drain plug. 
Figure 6  
2. Unscrew slowly the oil drain cap rotating it anti-clock wise using 
a 10mm hex key. Let the oil flow out. In the meantime clean the 
inside of the drain plug. 
3. After closing the drainage hole with its plug make the pump 
perform a number of turns, giving it a brief current pulse, so as to 
let residual oil in the pump chambers flow out. Then drain off the 
residual oil again. 
4. After the oil has been drained, close the drain plug tight; take the 
tank of waste oil away and clean thoroughly, using rags of cotton 
or other suitable material to dry.

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 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 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 SW60 oil. The SW60 
oil is a general purpose mechanical pump fluid specifically 
engineered to provide superior performance in high speed direct 
drive mechanical pumps. 

Technical Information 
Lubricants 
5 
MS40+ Single Stage Rotary Vane Pumps User Manual / 87-901-008-01 (E) 69/90 
These precisely distilled fluids (100 % solvent refined neutral 
paraffinic oil) deliver lower base pressure capability, faster pump-
down 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!  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. 
CAUTION!  To avoid the risk of contaminating the oil, absolute cleanliness of the pump and 
surrounding area must be ensured during the lubrication procedures.

SW60 Oil Description 
SW oil have superior features; 
 Reduced deposits, thanks to the absence of heavy metals 
(ashless); 
 Odorless; 
 Exceptional lubricating properties and protection against the 
most common solvents, and high oxidation resistance; 
 High anti-emulsifying power with water; 
 Minimal variations in viscosity according to temperature; 
 Very low volatility (vapor tension) and thus suitable for use on 
high vacuum pumps; 
 Resistance to aging under the effect of atmospheric agents (ozone, 
water, light); 
 Chemical and physiological inertia of primary importance, and 
extremely high anti-emulsifying properties. 
This special type of oil is suitable for use in environments containing 
noble or inert gases. 
The SW60 oil described is combustible. If during normal use the 
vacuum pump should take in mixtures with an oxygen content 
greater than 21 % or pure oxygen, this should cause: 
 Oxidation of the oil and thus the loss of its lubricating properties, 
with serious damage to the pump itself; 
 Formation of conditions favorable to explosion in the pump tank.

Communication Protocol 
The communication protocol is a MASTER/SLAVE type where: 
 Host = MASTER 
 Controller = SLAVE 
The communication is performed in the following way: 
1. the host (MASTER) send a MESSAGE + CRC to the controller 
(SLAVE); 
2. the controller answer with an ANSWER + CRC to the host. 
The MESSAGE is a string with the following format: 
<STX>+<ADDR>+<WIN>+<COM>+<DATA>+<ETX>+<CRC> 
Where: 
NOTE When a data is indicated between two quotes (‘...’) it means that the indicated 
data is the corresponding ASCII character. 
 <STX> (Start of transmission) = 0x02 
 <ADDR> (Unit address) = 0x80 (for RS 232) 
 <ADDR> (Unit address) = 0x80 + device number (0 to 31)  
(for RS 485) 
 <WIN> (Window) = a string of 3 numeric character indicating the 
window number (from ‘000’ to ‘999’); for the meaning of each 
window see the relevant paragraph. 
 <COM> (Command) = 0x30 to read the window, 0x31 to write into 
the window 
 <DATA> = an alphanumeric ASCII string with the data to be 
written into the window. In case of a reading command this field 
is not present. 
The field length is variable according to the data type as per the 
following table:

Electronic Self-Test 
When you switch the pump on with the main On/Off switch the pump 
doesn’t start immediately but it starts only after about two seconds. 
This test time isn’t required if the pump is already powered as when 
it is operated in remote or serial mode. 
Rotor Lock Test 
The rotational frequency is checked continuously. If the rotor 
remains still for more than 20 sec. the pump status is changed to 
“Fail”. 
Oil Level Check 
The oil level is continuously checked even when the pump is in Stop 
status. If the oil level check highlights at low level while the pump is 
OFF, it won’t starts again. If the oil level check highlights at low level 
during the pump operation, it will continue to run but, if you switch 
the pump off it will be impossible to start again. 
NOTE If the electronic controller status is “Oil Under-level” the pump starting is not 
allowed. 
NOTE If the oil level check fails (low level) the pump doesn't stop. The test only 
activates the output described above. 
An Oil level sensor fail is highlighted by means of quick status led 
blinking and RS232 window (see "Status led" and "Window meaning" 
tables).
