Variable speed booster sets

GPW is a variable speed pressurization system comprising two or three pumps assembled into one unit. It is electronically controlled by two or three STEADYPRES devices connected in parallel. These devices automatically adjust the pump operation based on the system's varying water demands, ensuring constant pressure. 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.
