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.
The pump, which is integrated in the mist blower, belongs to the category of high-pressure piston
diaphragm pumps that are made from approved materials for pumping plant protection products
and liquid fertilizers used in agriculture, fruit growing and viticulture.
11.1
Control before use
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. Make sure the oil level is within the marked
oil range (Figure 11.2). ). If the oil level is too low add some oil whereas be careful not to exceed
the maximum allowed level. Only use the oil grade and type specified on the identification plate
of the pump. If you intend to use another oil, consult the manufacturer of the pump or the machine.
Figure 11.1
The air pressure in the air chamber is
determined by the operating pressure of the
pump.
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.
Check if the valves are adjusted to allow the
flow of fluid from the reservoir to the pump.
Also check the throughput of the suction
filter insert and the suction hose (make sure
it is not bent).
11.2
Use
Before turning on the pump’s drive, check if the control valve is open (hold the switch on the
control panel [–] for approx. 30 seconds).
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.
