GEL equipments are manufactured with high-quality acid-resistant materials and submitted to severe
operating tests.
Follow these instructions to avoid any operating and servicing problems.

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.
In the pumps BABY 13, BOY C 15 SUPER, BOY C 30,
BOY C 130, BOY C 190, BOY C 230, the flow reverser
device (GEL patent) 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.
