GP3A

Variable speed pumping units

GP3A is a variable-speed pressure boosting unit comprising three electric pumps connected in parallel and integrated into a single assembly. The system is electronically managed by two or three interconnected PRO-DG controllers, which automatically adjust pump operation to match varying water demand, maintaining a constant system pressure under all operating conditions.
When water withdrawal reduces the system pressure, the first pump activates to meet the required flow rate, maintaining pressure at the set value. As the maximum rotation speed is reached, additional pumps start up in sequence to fulfill the system's water demand.
