INTENDED USE

 The pump is exclusively designed for use with chemical products such as pesticides and weed
killers in watery solution and always compatible with the materials the pump is made. The water
temperature must be between +4°C and +60°C.

The pump cannot be used with:
Watery solutions whose viscosity and density exceed those of water.
–
Chemical solutions for which compatibility with the materials the pump is made is unknown.
–
Seawater or water with high concentration of salt.
–
Fuels and lubricants of all kinds and types.
–
Inflammable liquids or liquefied gases.
–
Food-grade liquids.
–
Solvents and diluents of all kinds and types.
–
Paints of all kinds and types.
–
Fluids at temperature lower than 4°C or higher than 60°C.
–
Liquids containing granules or solids in suspension.
–
 The pump cannot be used for washing persons, animals, electric systems, delicate objects, the
pump itself or the system in which the pump is installed.
 The pump cannot be used in places where there are particular conditions, as, for instance, cor-
rosive or explosive atmospheres.
All other use is considered improper.
Idromeccanica Bertolini S.P.A. shall not be liable for any damage deriving from improper or incor-
rect use.

FAQ

Question: How much should you reduce the pump R.P.M. in order to get less flow?
Answer: Required R.P.M. = Expected flow x
Question: Which diameter the engine/ motor pulley should have to achieve these R.P.M.?
Answer: External diam. of the engine/ motor pulley =
Question: What's happening if it is not possible to replace the engine/motor pulley?
Answer: External diameter of the pump pulley =
engine/motor R.P.M
Question: If the engine/ motor is running at lower R.P.M. than the max. R.P.M indicated in the label,
which is the maximum flow rate to achieve?
Answer: Attainable maximum flow = Engine/motor R.P.M x Max. flow indicated in the label
Max. R.P.M. indicated in the label
Question: What is the approximate power required to achieve the max. performances allowed?
Answer: Required power (electric motor) (kw) = Max flow (L/min) x Max pressure (bar)
