MAINTENANCE INSTRUCTIONS 7
Lengthy pump lay-offs
It is important to comply with the recommendations for lay-offs in the operator's manual of the machine into
which the pump is incorporated.
For the pump itself, at the end of pumping operations it is essential to flush out the internal circuit by pump-
ing clean water. After this, open the intake circuit to the air and leave the pump in operation until the internal
circuit is completely empty. Following this simple procedure at the end of every operating session will prevent
the retention inside the pump of products which are often corrosive and may damage its hydraulic circuit in
the long-term.
If the pump is laid off during the winter in locations with severe weather conditions, it is very important to flush
out the internal circuit as described above and then draw diluted automotive anti-freeze into the pump. Then
take care to discharge the liquid from the system and the pump in particular; it usually has a specific drain plug.
Putting the pump back into service
Before putting the pump back into service after a long period out of use, check the oil level and the tightness
of the mounting screws.
Scrapping the pump
Used units must be disposed of in compliance with local legislation.
