maintenance of the e-SV pump. The instructions and
warnings provided below concern the standard version,
as described in the sale documents. Special versions may
be supplied with supplementary instructions leaflets.
Please refer to the sale contract for any modifications or

Improper use may cause personal injury and
damage to property and lead to the forfeiture of

The e-SV pump is a vertical multistage, non-self priming
pump which can be coupled to standard electric motors.
For the pump sizes 1SV-22SV , some of the metal parts
that are in contact with the pumped liquid are made of
stainless steel, others are made of cast iron. They are
available in different versions according to the position
of the suction and delivery ports and the shape of the
connection flanges. For the sizes 33SV-125SV , some of
the metal parts in contact with the pumped liquid are
made of stainless steel, others are made of cast iron. A
special version is available, in which all the metal parts
in contact with the pumped liquid are made of stainless
steel. If you purchase a pump without the electric motor,
make sure that the motor you use is suitable for coupling
to the pump. All e-SV pumps are equipped with a special
mechanical seal designed for easy replacement without
having to disassemble the entire pump.
These pumps are suitable for civil and industrial water
distribution systems, pressure booster, irrigation (agri-
culture, sporting facilities), water treatment, boiler feed,
parts washing, cooling - air conditioning - refrigeration
and fire fighting applications.
