Booster Sets GD Series

Booster Sets GD Series

Variable speed booster pump sets with DrivE-Tech and Drive-Tech MINI

The GD series booster sets consist of two or three identical electric pumps coupled in parallel via manifolds, shut-off valves, check valves and fixed on a single base.
The electric pumps are controlled by one inverter for each electric pump, which modulates the operating frequency in order to maintain a constant set value.
