Long Stops

If long productions stops are planned (more than 6
months) and the pump is emptied of water, it is rec-
ommended that the pump be secured as follows:
1. Remove the coupling safety guard.
2. Spray a couple of drops of silicone oil onto
the axle between the top section and the coupling.
Carefully follow the instructions given in the manual
provided by the pump supplier. Never store or install
the equipment where the ambient temperature is
above 40°C or gets at or below the freezing point.

placed with a smaller or larger nozzle depending on
110003606

7.3. Maintenance, trouble shooting and Service

Maintenance Instructions
1. Quick couplings; it is recommended to lubricate
all couplings parts regularly, approx. once a
month) by water proof grease to prevent leaks
and damage of o-rings.
2. If the quick couplings leak, o-rings should be
110003827
replaced.
Due to the following it is very important
to close water, air and chemical suplly
when the unit not in use.
• If the air supply is open when the unit
is not in use - air might seep into the
water pipe - which means that the
system has to be bled again.
