Lowara SVH Pump
• Flow rate: up to 120 m3/h
• Head: up to 241 m

The basic function of the HYDROVAR device is to control the
pump to meet the system demands.
HYDROVAR 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 will automatically provide for the cyclic
changeover of the pumps’ starting sequence.
In addition to these basic functions, HYDROVAR can
perform controls only manageable by the most advanced
computerized control systems. Some examples are:
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 over-voltage, undervoltage,
overload, and earth fault.
• Vary the pump speed: acceleration and deceleration time.
• Compensate for increased flow resistance at high flow
rates.
•Conduct automatic tests at set intervals.
• Monitor the converter and motor operating hours.
• Display the energy consumption (kWh).
• Display all functions on an LCD in different languages
(Italian, English, French, German, Spanish, Portuguese,
Dutch, etc...).
• Send a signal to a remote control system which is
proportional to the pressure and frequency.
• Communicate with external control system via Modbus
(RS 485 interface) and Bacnet as standard.
