PUMPS
Pumps are a vital element of spraying appliances. The reliability and a long durability of the pump also
depend on how you treat the pump and whether you use and maintain it correctly.
IMPORTANT:
The standard version of all pumps is equipped with membranes which are made of
NBR rubber. Therefore it is the user’s duty to use only chemical agents for spraying which do not
harm this kind of material. On the opposite, the manufacturer cannot be held responsible for any kind
of damage that could occur. If you would like to use VITON or DESMOPAN membranes, consult the
technical service about proper operation.

CONTROL BEFORE USE
Figure 10.2
When the pump is not operating, check the oil quantity
in the housing of the pump. Also check the oil level
every single time before filling the reservoir. The level
must be within the limits which are marked on the oil
lid or in the oil pot (depends on the version of the
pump). If the oil level is too low add some oil whereas
be careful not to exceed the maximum allowed level.
The air pressure in the air chamber depends on the
working pressure which can be found in the diagram on
the left. The air pressure in the air chamber must never
be higher than the working pressure of the pump.
