APPLICATION
The EVOTRONIC pump is a horizontal
self-priming multi-stage pump for pump-
ing clean liquids without solid suspended
particles, fibers, or abrasive materials
that may chemically or mechanically at-
tack the pump, or liquids not compatible
with the pump construction material.
The pump can be used to pump water in:
• water distribution systems
• irrigation systems
• rain water collection systems
EVOTRONIC is a pre-assembled and pre-
wired unit made up of a pump, expansion
tank, fittings, pressure switch, equiped
with electronic device with inverter tech-
nology allowing to keep a constant pres-
sure in the system. The device:
• starts and stops the pump according
to opening or closing of utilities.
• reduces water hammer effect.
• is ready to use
• protects the pump from dry running
and motor overloads
• runs an auto-diagnosis: in case the
set point fixed by the user is too high
for the hydraulic installation system
available, the pump recalculates the
right pressure set point automatically.
The expansion tank has a membrane that
divides it into two compartments; one for
water and one for gas. The water section
serves to collect and deliver fluid in the
event of a request from a utility. The gas
in the relative section is compressed on
collection of the fluid and decompressed
when the fluid is then delivered to the
utility. The pump increases the pressure
and conveys the fluid to the utilities via
the pipelines. the pump is started up or
stopped by the inverter device that ad-
justs the motor rotation speed according
to the real water demand. The electronic
device keeps a constant pressure accord-
ing to the selected set point. As the water
demand decreases, the device reduces
the pump speed until it stops.
The expansion tank influences the pump
start-up and shutdown cycles.
In order to optimize the correct operation
of the electronic device, it is necessary to
adjust the set-point (fixed ion the factory
) to the specific features of the installation
system.
Never use the pump for flamma-
ble and/or explosive liquids.
Improper use of the pump can
lead to physical injury and/or
material damage. Improper use
of the product will render the warranty
null and void.
Note
The pump is designed for use with drink-
ing water destined for human use (ACS).
