2 - THE ADVANTAGES OF THE PUMPS WITH FLOW REVERSER

Time and, above all, temperature increase make calcium
salts, usually present in water, precipitate in the form of
microcrystals and settle on metallic surfaces of pipes,
plant coils and heat exchangers, thus reducing flow rate
and thermal efficiency.
To restore the original plant performance it is necessary
to carry out a descaling with specific products and
equipments.
The flow reverser device attacks scale on both sides, thus
making descaling particularly fast (as the normal dissolving
action is combined with the detachment in flakes of the
scale, made friable from the double attack) and effective,
even when pipes and exchangers are almost totally
clogged.
