e-SV™ SERIES - VERSION WITH HYDROVAR
TM
OPERATING PRINCIPLE
The basic function of the HYDROVAR
TM
device is to
control the pump to meet the system demands.
HYDROVAR
TM
performs these functions by:
1) Measuring the system pressure or flow via a
transmitter mounted on the pump’s delivery side.
2) Calculating the motor speed to maintain the correct
flow or pressure.
3) Sending out a signal to the pump to start the motor,
increase speed, decrease speed or stop.
4) In the case of multiple pump installations, HYDROVAR
TM
will automatically provide for the cyclic changeover of the
pump’s starting sequence.
In addition to these basic functions, HYDROVAR
TM
can do
things only by the most advanced computerised control
systems, such as:
• Stop the pump(s) at zero demand.
• Stop the pump(s) in case of water failure on the
suction side (protection against dry running).
• Stop the pump if the required delivery exceeds the
pump’s capacity (protection against cavitation caused
by excessive demand), or automatically switch on the
next pump in a multiple series.
• Protect the pump and motor from overvoltage,
undervoltage, overload and earth fault.
• Vary the pump speed acceleration and deceleration time.
• Compensate for increased flow resistance at high flow
rates.
• Conduct automatic test starts at set intervals.
• Monitor the converter and motor operating hours.
• Display all functions on an LCD in different languages
(Italian, English, French, German, Spanish, Portuguese,
Dutch).
• Send a signal to a remote control system which is
proportional to the pressure and frequency.
• Communicate with another HYDROVAR
TM
or control
system via an RS 485 interface.
TYPICAL EXAMPLE OF ENERGY SAVINGS
System: 22SV07F75T vertical multistage electric pump with 7,5 kW motor equipped with HYDROVAR
TM
, 70 m head.
19 hour/day operation.
Application: maintaining a constant pressure as the flow rate varies according to the system curve.
