Energy saving multi pump drive from WEG

Energy saving multi pump drive from WEG
WEG has introduced its CFW-08 Multi-pump AC drive, a new system that saves energy in pumping systems, by allowing the control of up to four pumps from one variable frequency drive (VFD). "There are multiple advantages to installing a Multi-pump variable frequency drive system," says WEG's Graham Johnson. "These include energy saving, extended operating system life, system default diagnosis, constant line pressure and pump operation time equalisation."

By controlling up to four pumps simultaneously, the WEG CFW-08 Multi-pump system enables constant pressure to be maintained in pipelines regardless of fluctuations in outflow demand. This is achieved using a PID controller in conjunction with the auxiliary pumps' start/stop logic. In addition, the CFW-08 also monitors the pressure and level of the capture reservoir, and provides minimum output pressure fault monitoring for broken pipes or cavitation, and maximum output pressure fault monitoring for blocked or obstructed pipes. Designed for operation in the range 0.25kW to 15kW, the CFW-08 is easy to configure, install and operate.
