The Vacon 100 Flow is an ac drive specifically designed to improve flow control for multi-pump applications in which several pumps are used in place of a single one. Multiple pump solutions are desirable to lighten the load by spreading it across several pumps, thus providing greater energy efficiency and system redundancy. If one pump fails, the others can take up the additional load. For operations in which demand fluctuates throughout the course of the day, such as a municipal water system providing peak water consumption in the morning and minimal usage at night, the Vacon 100 Flow offers unsurpassed 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. The Vacon 100 Flow AC Drive is equipped with built-in standard Ethernet, eliminating any additional options or gateways needed to communicate with process automation. This also provides access for commissioning and maintenance through “Vacon Live” and makes local or remote monitoring possible.
