to avoid in pressure drops, use hoses, accessories
and control and regulation elements whose deliv-
ery and pressure characteristics are suitable to the
pump’s own characteristics.
most snap-on fittings cause pressure drops.

3. Connect the supply hose from the net work to the pump circuit.
4. Adjust the network pressure of the compressed air to guarantee a pressure of
NOT LESS THAN 2 bars AND NOT MORE THAN 7 bars when the pump is running. For
Piusi MA and Piusi MP pumps equipped WITH RUBBER BALLS, DO NOT EXCEED 5
bars. Lower or higher pressure may cause functional problems or pump breakage,
product spills and damages to persons or objects.
5. In the event that the pump stalls, whatever may have caused the stall must be
eliminated (see page 66), after which reset by rotating the manual device by half a
turn in an anti-clockwise direction. Wait for the pump to re-start and re-screw the
reset device.
6. If the number of pump cycles needs to be recorded or displayed, install the
STROKE COUNTER.
7. Always protect the pump from possible accidental collisions with moving objects
or various blunt materials that may damage it or react on contact with it.
8. Protect the site and the persons from accidental failures by installing a protection
guard to hold and collect any product leakage: DANGER OF SERIOUS INJURIES AND
DAMAGE TO HEALTH AND/OR OBJECTS.
9. If the diaphragms are completely torn, the fluid may enter the air circuit, damag-
ing it, and be discharged through the exhaust port. It is therefore necessary that the
air exhaust be conveyed by pipes to a safe area.
to feed more than one pump with the same air
control device, please ask our engineers.
