High vacuum pumps, exhausters and blowers operating manual 

18 

WARNING 
The silencers must be installed on the blower flanges making sure that their weight is not supported by the 
machine  itself  and  they  do  not  cause  any  deformation  to  the  machine.  During  flange’s  bolts  tightening 
operation check the free manual rotation of the shaft.  
 

 

5.6 - SOUNDPROOFING BOOTH 

In case of high speed and/or high back-pressure the use of a soundproofing booth may be needed. 

 

WARNING 
Said booths shall allow air circulation for an appropriate cooling of the machine. Forced ventilation may be 
necessary. 
 
 

5.7 - ANTISHOCK MOUNTS

 

They allow to damp the vibration that otherwise would be transmitted to the foundation. They are recommended for the 
positioning between pump bracket and support plane for blowers and exhausters. 

 
5.7.1 - ELASTIC HOSE 

Must be used in case of antishock mounts: it avoids the transmission of mechanical vibrations to the pipes and allows 
their free heat elongation. 

 
5.8 - VACUUM AND PRESSURE GAUGES 

Their  use  is  recommended  to check  that  the  system  is  operating  correctly  and  to  check  the  adjustment  of  the  over-
pressure valve. 
 

5.9 - CHOKED AIR FILTER GAUGE 

It is particularly recommended for machines that are not constantly checked or closed in a  soundproofing booth. 
A pressure switch installed in the appropriate boss on the suction flange shall actuate an  alarm signal and in case 
shut off the motor, keeping under control the vacuum level given by filter . 
 

5.10 

– MOTOR ELECTRICAL PROTECTION 

On the electric feed line, install a thermo-magnetic switch properly adjusted as a protection against feed problems. 

 

5.11 - ANTI ACCIDENT DRIVE COVER 

If the coupling between the pump and the electric motor is not made by Pompetravaini  - Bora, please note that, in all 
cases  a  protection  must  be  provided  in  order  to  avoid  contact  with  moving  parts  using  a  cover  conforming  to  the 
regulations in force. Pompetravaini - Bora does not assume any responsibility for anti accident drive not manufactured 
or supplied by itself. 

 

 

6 – INSTRUCTIONS FOR USE 

 

 

6.1 - OPERATION

 

Blowers,  exhausters  and  vacuum  pumps  described  in  this  manual  are  rotary  machines  equipped  with  lobe  rotors, 
symmetrically arranged and counter rotating, contained inside a housing. The rotor rotation is synchronized by means of 
a gear transmission so as to move forward without a mutual contact with little clearance between them and with respect 
to the housing. The operating principle is indicated below.
