With this system, a check valve (1) must be fitted on the delivery tube to prevent the transfer of sewage inside the
Rotary blades vacuum pump.
3.3 ASSEMBLY AND FITTING - INSTALLATION
The Rotary blades vacuum pump should be assembled and installed using the following procedure:
1) Assemble the Rotary blades vacuum pump horizontally with its feet facing downwards. The assembly position on the vehicle
should be easy to access and be protected. A 5° maximum longitudinal slope of the vacuum/pressure blowers pump with
respect to the horizontal plane must not be exceeded.
2) Bolt the Rotary blades vacuum pump using screws and nuts passing through the specially provided slots or holes in the feet;
3-M/K) To install the .../M-K version Rotary blades vacuum pump, connect the cardan shaft at 540 r.p.m.of the tractor to the P.T.O.
shaft of the Rotary blades vacuum pump.
3-MA/KA) To install the .../MA-KA version Rotary blades vacuum pump, connect the cardan shaft at 1000 r.p.m.of the tractor to
the P.T.O. shaft of the Rotary blades vacuum pump.
Do not exceed the maximum slope permitted for the cardan shaft.

The Rotary blades vacuum pump can be used as a mixer
by fitting, on request, a double outlet on the manifold (see
Figure 2). In this case there will be the intake of a normal
Rotary blades vacuum pump, but a perforated tube placed
inside the tank car must be used for the compression.
When the handle is positioned on the compression phase,
the air will be forced out through the holes in the tube so
causing mixing of the previously loaded sewage (never
exceed the maximum working absolute pressure of 2,5
bar) equal to 1,5 relative bar.
