11.1.2 - WASHING OF OIL TANK

Wash the oil tank at least once a year. Remove the manifold, and then wash it using solvents.

11.1.3 - WASHING AND CLEANING OF VALVES

Wash and clean the valves at least once a month. Remove the valves, then wash them with water or, if necessary,
non-corrosive detergents.

11.2 - VALVE CHECK

Regularly check that all the valves, for both overfl ow and pressure/vacuum, are still working effi ciently.

THE BLADES

11.3.1 - "LONG LIFE" BLADES GENERAL INFORMATION

The LONG LIFE blades are made from a special material suitable for industrial uses for rotary blades
vacuum pumps used in the agricultural fi eld. These blades offer excellent resistance against wear and thermal
and mechanical stress. It is suitable for the most common uses and for the suction of denser sewage. It is
recommended for systems used by contractors and also for frequent and repeated uses during the same day.
Apart from normal wear, it may be necessary to replace the blades following incorrect use of the Rotary
blades vacuum pump. The most frequent causes come from heat, lack of lubrication, entrance of sewage, high
pressure or vacuum, formation of rust inside the body due to prolonged inactivity.
With the heat too high pallets stretch to touch the plate front and rear, this causes the breakdown of the pallets.
Lack of lubrication means the blades are completely dry like the inside of the pump. This increases their
fragility and causes them to break lengthways.
The same type of breakage can be caused by entrance of sewage or by a too high working pressure.
A too high vacuum causes the blades to beat against the cylinder with consequent damage to the outside of the
blades. Moreover, the lining becomes wavy.

BLADES INSPECTION

the blades in the rotary blades vacuum pump proceed as follows:
To check the state of wear of
1) remove the threaded cap using a fork wrench;
2) insert into the inspection hole a round profi le (ø 6 mm, length 135 mm);
3) rest one end of the round profi le on the rotor;
4) trace the round profi le at the height of the inspection hole;
5) rotate the rotor until one blade is aligned with the inspection hole;
6) insert the round profi le in the slot of the blade;
7) trace again the round profi le at the height of the inspection hole (see Figure 10);
8) measure the distance between the two traces on the round profi le;
9) if this distance is more than 10-15% of the original height of the blade (see Table 6), replace the full set of blades;
10) close the inspection hole by tightening the threaded ca
