instruction manual
for use and maintenance of BLM series
The BLM pump must be placed vertically on a flat horizontal surface with a maximum inclination of
5° and fixed by means of screws that lock the feet.
All installation operations must be carried out with the utmost care by suitably trained personnel and
with the power take-off disconnected.
During installation operations, it is advisable to use
the personal protection equipment listed to the side.
Should it be necessary to paint the vacuum/pressure blowers pump, do not paint the identification plate,
the oil level indicator and the vent plugs.
Always avoid the entry of liquids arriving from the tank inside the vacuum/pressure blowers pump. IT IS
therefore necessary to provide a system for the interception of the liquids coming from the tank in order
to prevent their entry into the pumping zone.
Provide a noise reduction system both for the main air circuit and for the cooling circuit.

The vacuum/pressure blowers pump should be assembled and installed using the following procedure:
1) Assemble the vacuum/pressure blowers pump horizontally with its feet facing downwards.
2) Bolt the vacuum/pressure blowers pump via passing screws and nuts in the appropriate slots or holes provided in the feet.
3) For the operation of the vacuum/pressure blowers pump, it is necessary to connect the 1" 3/4 PTO of the pump to the cardan shaft.
4) Then connect the intake/compression pipe of the tank car to the BLM vacuum/pressure blowers pump tightening it to the adjustable
elbow using metal clamping bands in relation to the diameter of the pipe.
Do not exceed the maximum inclination permitted by the cardan shaft.
