2.4.1 - BASIC FIRST AID

In the event dangerous substances have been inhaled and/or come in contact with the human body, immediately follow
the instructions given in the company’s internal medical safety procedures.

3 – DESCRIPTION

The lobe pumps are volumetric machines that, thanks to the rotation of two rotors with three lobes within a suitably
shaped chamber, create volumes and transfer air through the intake manifold to the outlet one. The rotor lobe rotation
without contact is synchronized by means of gears and it occurs completely dry without any lubrication or residues
generated by brushing or contact during rotation.
The gear toothed wheels that allow the rotors and their bearings to rotate are lubricated with oil and are inside two
compartments (separated from the rotor rotation chamber by means of gaskets) and they function as a tank for
the lubricating oil. During operation they are at the same pressure of the pump work chamber. For this reason it is
forbidden to open the oil filler and drain plugs during operation or until the atmospheric pressure has not been restored
inside the pump.

3.1 – DESCRIPTION OF TYPES
This manual includes all the pumps belonging to the series described below. The available models and their variants are
always evolving. The manufacturer reserves the right to update the range of pumps, consequently.

3.1.1 - BLOWERS
