The VACON® 100 FLOW from VACON (Milwaukee, WI) is an AC drive designed to improve flow control for multi-pump applications in which several pumps are used in place of a single one. The drive offers control of flow and pressure for a maximum of eight pumps (or fans) without the need for an external controller — communication between drives is provided by integrated RS-485. It is equipped with built-in Ethernet as standard, eliminating additional options or gateways needed to communicate with process automation. The drive offers three multi-pump control solutions: single-drive multi-pump, multi-drive multi-master, and multi-drive multi-follower.
