Damage prevention and safety instructions
A Warning! Observe limitations of use.
B The name plate voltage must be the same as the
mains voltage.
C Connect the pump to the mains via an omnipolar
switch with at least a 3 mm opening between
contacts.
D Install a high-sensitivity differential switch (0.03A)
as extra protection against lethal electric shocks.
E Connect the pump to the ground.
F Use pump only
indicated on the name plate.
G Remember to prime pump.
H
Check for motor self-ventilation.

1. GENERAL INFORMATION
Please observe the following instructions to achieve
the best pump performance possible and a trouble
free installation.
Read these instructions before installing the
pump.
Save them for future reference.
These are multistage centrifugal pumps having
more than one impeller assembled in-line. The
same flow passes through each impeller but the
pressure increases each time, i.e. more impellers,
more pressure.
These pumps are designed to operate with clean
water, free from particles in suspension and with a
maximum temperature of 40 ºC.
Correct pump operation is assured providing
the instructions on electrical connection,
installation and use are strictly adhered to.
Failure to adhere to the instructions can
result in premature failure of the pump and
voiding of the warranty.
Minimum efficiency index (V models only)
With the application of the European Regulation
547/2012, the minimum efficiency index after
01/01/2015 must be MEI ≥ 0.40.
The reference value for the most efficient hydraulic
pumps is rated at MEI ≥ 0.70.
The performance curves and efficiency charac-
teristics can be checked on the technical cata-
logues.
The operation of this hydraulic pump with variable
operating points can be cheaper and more efficient
when controlled with, for example, a speed regula-
tion control that adjusts the pump's operation to the
system performance.
