The BS Series - M/E variable speed pressure boosters consist of one or more pumps and are equipped with inverter devices and pressure transducers. The operation of BS Series - M/E units are designed to work with an inverter for each pump motor or a common VFD for all pump motors depending on user requirement. The management of the system with the inverter maximises energy savings, promptness in responding to pressure changes, reduction of management costs and acoustic comfort. They are ideal for applications such as water supply, civil and industrial construction.
