4. Choice of type of Pump and Design of Plant
With regard to safety, all pumps comply with the regulations UNI EN 809. The
type of pump must be chosen by the manufacturer in relation to the nature of the
liquid to be used and to the technical characteristics (flow capacity, pressure etc.)
to be achieved.
The use of the pumps with incompatible materials may be hazardous, posing a danger to
personal and environmental safety.
When connections are made with electrical motors all related instructions should be
followed as set out in the relevant regulations EN 6024.1, to avoid risks deriving from the
use of electricity (cf. relevant part dealing with installation).
Bertolini "IDB" membrane pumps are designed from materials which are
compatible for use with water and the majority of pesticide and weed-killing
products currently on sale in the market in the concentrations advised by the
manufacturers(Cf. table at page 23).
The technical data relating to the pumps performance characteristics (no. revs/l, flow
capacity and maximum pressure) are set out on the plate affixed to the pump.
For further information refer to the Bertolini Technical Assistance Service.
The plant manufacturer is responsible for ensuring the correct choice and size of
the driving system, including in relation to the risk to personal safety that may
be caused by the choice of system.
The fitting of the pump with (electric or thermal) motors or transmission systems
with performance characteristics differing from those advised may cause situations posing
danger to personal safety or the environment.
Particular care must be taken by the manufacturer in the design and construction of the
plant to avoid risks of personal injury deriving, not from the pump, but from the design,
construction or improper use of the plant on which the pump is installed.
