DETAILS
A second way of splitting (named COMBI) consists of using several pumps in parallel (up to 8) each one driven by a device unit.
In this way, efficiency and the reliability of the pump group is maximized.
Each device controls and protects its pump and the operation is shared among all the connected pumps to average pump wearing; in case of failure the remaining pumps will maintain the pumping operation.
The booster system is equipped with up to 8 pumps connected to external frequency converters (one per pump).
Booster set maintains a constant pressure through continuous adjustment of the speed of the pumps.
The system performance is adapted to the demand through cutting in/out the required number of pumps and through parallel control of the pumps in operation.
Pump changeover is automatic and depends on load, time and fault.
Each pump in operation will run at individual speed.
