This configuration from the Smart Digital S range is specifically engineered with a Sapphire sensor to ensure safety and precision when handling FSA in water treatment networks at scale.\u003c\/p\u003e \u003cp\u003ePowered by a 24 W motor, the unit produces a maximum flow rate of 30.0 L\/h against a 4 bar maximum operating pressure. It utilises a 1000:1 turn-down ratio, allowing for consistent volumetric accuracy across a broad range of flow settings down to a minimum of 30.0 ml\/h to match the available site chemical demand.\u003c\/p\u003e \u003cp\u003eThe hydraulic design centres on advanced stepper motor technology, providing smooth and continuous dosing. This model incorporates FlowControl to continuously monitor the dosing process, while AutoFlowAdapt automatically compensates for changes in process pressure to maintain accurate dosing.\u003c\/p\u003e \u003cp\u003eMechanical durability is provided by a PVDF pump head, PTFE gaskets, and the specialised Sapphire sensor for aggressive media. The unit includes communication functions available according to the selected control variant. It is rated for liquid temperatures up to 45°C and is housed in a robust IP65 enclosure.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eSapphire sensor technology for accurate diagnostic dosing of Fluorosilicic Acid (FSA).\u003c\/li\u003e \u003cli\u003eFlowControl 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 enables precise adjustment from 30.0 L\/h down to 30.0 ml\/h.\u003c\/li\u003e \u003cli\u003eStepper motor technology provides smooth and continuous dosing.\u003c\/li\u003e \u003cli\u003ePVDF pump head, PTFE gaskets and ceramic ball valves for aggressive chemical resistance.\u003c\/li\u003e \u003cli\u003eCommunication functions available according to the selected control variant.\u003c\/li\u003e \u003cli\u003eIP65 rated enclosure protects the unit in challenging site installations.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974841241847,"sku":"93297812","price":7667.17,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dda-30-4-sapphire-sensor-digital-dosing-pump-wastewater-chemical-dosing.png?v=1785153924","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dda-30-4-sapphire-sensor-digital-dosing-pump-wastewater-chemical-dosing","provider":"Foundation Pumps","version":"1.0","type":"link"}
