CHAPTER 2

APPLICATION

The EVOTRONIC pump is a horizontal self-priming multi-stage pump for pumping clean liquids without solid
suspended particles, fibers, or abrasive materials that may chemically or mechanically attack the pump, or liquids
not compatible with the pump construction material.
The pump can be used to pump water in:
• water distribution 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 technology allowing to keep a constant pressure 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
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 adjusts the motor rotation speed according to the real water demand. The electronic device
keeps a constant pressure according 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.
DANGER
Never use the pump for flammable and/or explosive liquids
DANGER
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 drinking water destined for human use (ACS).
APPLICATION LIMITS
• Temperature of pumped
liquid: from +5°C to +50°C in
compatibility with the pump
materials.
the data plate (Figure 5) lists the specifications:
• irrigation systems
• 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
• Maximum ambient temperature:
+40°C;
USE AND MAINTENANCE MANUAL
• rain water collection systems
installation system available,
the pump recalculates the right
pressure set point automatically
• Max. operating pressure: 8bar
(0.8MPa);
