About Booster pump GV
The Lowara GV series booster sets are fully automatic booster sets for water supply. They are equipped with 2-6 pumps (where one can be a jockey pump), pressure transmitters and control panel including a SD60 controller and a variable frequency drive, all mounted on a frame for easy installation. One pump is speed controlled and the rest operates at full speed. With the SD 60 controller it’s easy to set and check the performance either on site or remote via Modbus or internet.
The GV series can be fitted the following pumps:
- Vertical multistage pumps e-SV series from 15 to 125
- End suction pumps e-NSC and e-SH series from 32 to 80 (on request)
In GVF series booster sets only one electric pump operates at variable speed, while the others operate at fixed
The pump is driven by a frequency converter directly inside the electric panel; the other pumps, up to a maximum
of five, are started by contactors.
All the pumps are controlled by the SD60 control unit which is on the front of the electric panel door.
The pump driven by the inverter modulates its speed according to the system demand, while the other pumps
run at maximum speed.
The first pump to start will always be the one connected to the frequency converter, the other pumps will start
in sequence after the first. It is possible to have automatic alternation of the fixed-speed pumps to distribute
wear and allow the pumps to operate for a uniform number of hours.
Starting and stopping of the pumps is determined according to the set value of pressure in the control board
menu. The pressure value is read by a pressure transducer connected to the SD60 control unit.
