Standard tools are required for the pump
maintenance but to facilitate the mounting
and dismounting operations of some pump
components, you will find the drawings to
make some tools on page 21.
14. PUMP STOPPED FOR LONG TIME
Before starting the pump for the very first
time after a long period from the date of
shipment check for the correct oil level,
check the valves as indicated in chapter

procedures indicated in chapter 10. When
a long inactivity is scheduled drain the
entire suction and delivery line and then
run the pump dry only for a few seconds
in order to drain out the water collected
inside the fluid end.
15. PRECAUTIONS AGAINST FREEZING
In the risk of freezing the following
precautions should be taken:
- After use drain the entire suction and delivery lines
(filter included) by means of discharging devices,
provided and positioned specifically for this purpose
along the lowest point of the lines.
- Run the pump only for a few seconds in order to
drain the water collected inside the fluid end.
Or when applicable
- Add a recommended amount of anti-freeze into the
water tank and run the pump until the anti-freeze
works all through the system.
If a pump is frozen or appears frozen ON NO ACCOUNT
SHOULD THE PUMP BE OPERATED until the entire
system has been thawed out.
