This DDA FCM-C system is engineered with a Sapphire sensor to provide the necessary diagnostic feedback and material compatibility for aggressive chemicals that degrade standard monitoring equipment.\u003c\/p\u003e \u003cp\u003eOperating on a 240v supply, the unit consumes 24 W of power while delivering a maximum dosing capacity of 17.0 L\/h at a 7 bar maximum operating pressure. It features a 1000:1 turn-down ratio, allowing for consistent volumetric accuracy down to a minimum flow of 17.0 ml\/h to meet diverse site chemical requirements.\u003c\/p\u003e \u003cp\u003eThe hydraulic assembly utilises stepper motor technology to produce smooth and continuous dosing. FlowControl continuously monitors the dosing process, while AutoFlowAdapt automatically compensates for changes in process pressure to maintain accurate dosing.\u003c\/p\u003e \u003cp\u003eMechanical integrity is provided by a PVDF dosing head, PTFE gaskets, and a specialised Sapphire sensor for FSA duty. Connectivity is a core feature, with communication functions available according to the selected control variant. Housed in an IP65 enclosure, it is rated for liquid temperatures up to 45°C.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eSapphire sensor provides accurate measurement and safety for Fluorosilicic Acid (FSA) dosing.\u003c\/li\u003e \u003cli\u003eFlowControl with Sapphire sensor monitors the dosing process and detects abnormal operating conditions.\u003c\/li\u003e \u003cli\u003eAutoFlowAdapt automatically compensates for changes in process pressure to maintain accurate dosing.\u003c\/li\u003e \u003cli\u003e1000:1 turn-down ratio from 17.0 L\/h down to a minimum of 17.0 ml\/h.\u003c\/li\u003e \u003cli\u003eStepper motor drive provides smooth and continuous dosing.\u003c\/li\u003e \u003cli\u003ePVDF pump head, PTFE gaskets and ceramic ball valves for aggressive fluid compatibility.\u003c\/li\u003e \u003cli\u003eCommunication functions available according to the selected control variant.\u003c\/li\u003e \u003cli\u003eIP65 rated enclosure ensures durability in site installations.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974841209079,"sku":"93297809","price":7325.45,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dda-17-7-sapphire-sensor-digital-dosing-pump-water-disinfection-flowcontrol.png?v=1785153921","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dda-17-7-sapphire-sensor-digital-dosing-pump-water-disinfection-flowcontrol","provider":"Foundation Pumps","version":"1.0","type":"link"}
