9 - START, OPERATION, STOP
9.1 STARTS
The Rotary blades vacuum pump does not have a start button. Therefore to start it just transmit the motion to the power take-off
(P.T.O.). The way this is done depends on the version of Rotary blades vacuum pump. Before starting make sure that the rotary
blades vacuum pump is supplied with oil for internal lubrication (and lubrication of gearbox in versions …/M-MA and …/K-KA).
Before starting the rotary blades vacuum pump, make sure that the guards on all the moving parts are in place and
efficient. Any damaged or missing components must be replaced and installed correctly before using the transmission.
For the M, MA, K, KA and D versions clean and grease the power take off before inserting the cardan transmission.

Operating time Ballast at vacuum -0.70 bar [min] continuous continuous
Once the desired vacuum has been reached it is advisable to reduce the rotations of the rotary blades vacuum pump.
The volume of air to be suctioned is only what corresponds to the volume of liquid loaded in the tank.
This simple measure, which does not increase the loading time of the tank, translates into lower consumption of the
blades. Do not use the rotary blades vacuum pump at the maximum rotation speed indicated on the identification
plate for longer than two minutes.
The capacity and degree of vacuum inside the tank can be adjusted by changing the speed of rotation and by not
using the vacuum control and pressure surge valves.
If the rotary blades vacuum pump is stopped with vacuum in the tank greater than -0.80 bar it is completely normal
that the entrance of air through the vacuum adjustment valve will take the depression in the tank to -0.80 bar.
Do not use the rotary blades vacuum pump at pressures, temperatures and for a time greater than what is indicated
in Table 5. During use, do not exceed the conditions of speed and power established by the manual. Do not overload
the machine or suddenly engage the P.T.O.
For correct operation of the pump, at the end of the loading or unloading cycle it is advisable to operate the pump
at 700 rpm without suctioning/compressing the air inside the tank for approximately 2 minutes in order to lower
the temperature inside the pump.
For correct use of the pump, it is advisable to start loading with the stemgate of the suction tube open, avoiding
creating a vacuum in the tank and then open the stemgate.
For correct operation of the pump, it is advisable before starting work to operate the pump at 700 rpm without
suctioning/compressing the air inside the tank for approximately 2 minutes to ensure pre-lubrication of the pump.
