1.1 - GENERAL DESCRIPTION

The BLW vacuum/pressure blowers pump is suitable to be used as an air compressor/decompresser, combined with a watertight tank suitable to be
put into vacuum and under pressure the liquid loading/unloading/distribution. The vacuum/pressure blowers pump is equipped with three adjustable
bends.
One bend is in communication with the tank, the other in the atmosphere and the third one is connected to the Ballast cooling. By appropriately
turning the reversing gear inside the vacuum/pressure blowers pump, it is possible to connect the intake to one of the elbows creating where
necessary vacuum or pressure inside the tank.
Pumping of the air is obtained through the rotation of two suitably shaped rotors that counter-rotate in relation to each other.
The incoming air is trapped in a chamber formed by the body and the rotors thanks to the particular shape of the latter and discharged to the output.

PUMP FOR BLW VACUUM/PRESSURE BLOWERS
VERSION BLW / P (FOR PULLEY APPLICATION)
CW standard
VERSION BLW / PM (FOR PULLEY APPLICATION)
Neither a cooling system nor lubrication is required
in the pumping zone: the air discharged into the
atmosphere is also free from pollutants such as oil,
resins etc...
The pumping capacity is obtained by careful control
of the distances of the rotors from each other and
with the body of the vacuum/pressure blowers pump.
