pump selection for spray nozzles

[mas26amin]

Dears,

I would like to select pump for some spray nozzles of dust suppression.
inlet water of nozzles should have below specification:
- Q = 3.8 lit/min
- P = 4 bar

Which type of pump do you propose for this specification?

A small one.

A little centrifugal type pump would appear to be the simplest and cheapest pump.

Just search small water pump 4l/min.

e.g.

small units ight not be suitable for constant running so talk to the supplier.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

3.8 l/m total or each nozzle?
