8.1 TESTING
All the Rotary blades vacuum pump Battioni Pagani are tested before the delivery at our plant.
In order to test the Rotary blades vacuum pump check the preceding points, using a workbench
if necessary.
Make sure that the P.T.O. shaft turns freely and that the direction of rotation is the same as the
one indicated by the arrow.
If operation of the pump is checked without it being connected to the suction/delivery tubes there will be danger
to operators' hands due to access to the inside of the discharge elbow. In this situation there is also the danger
that foreign bodies will be sucked into the machine.
Check that the position of the handle is correct and test that the Rotary blades vacuum pump exhausts or
compresses.
8.2 RUNNING IN
The running in period foreseen for a rotary blades pump is of 30 of effective working. During that period the working parameters
must be reduced of 20%

Pressure: the maximum allowed pressure is 2,5 absolute bar (1,5 relative bar).
In order to avoid exceeding this value or to obtain a lower max pressure, an over-
pressure valve, "C", must be applied that is of a size capable of discharging the
excess air delivery.
Vacuum: too high a vacuum may cause ovality and waviness of the body or
breaking of the blades.
It is therefore advisable to use a vacuum regulator valve, "D". These valves may
be fitted on the manifold cover or on manifold of the Rotary blades vacuum pump.
Vacuum working degree is of –0,80 bar.
The regulation of the valves is done by acting on the throttle placed on the valve
same (overpressure valve) or action on nut and locknut (vacuum adjustment
valve).
8 - TESTING AND RUNNING IN
ATTENTION: the installation must be always
equipped with depression valve (set at –0,80 bar) and
with overpressure valve (set at 1 bar).
