This Smart Digital S system is optimised for industrial service where consistent chemical delivery must be balanced with advanced monitoring functions to prevent unplanned interruptions.\u003c\/p\u003e \u003cp\u003eThe pump delivers a maximum dosing capacity of 12.0 L\/h and is rated for operation against a 10 bar maximum backpressure. Driven by a 24 W motor, it offers a 1000:1 turn-down ratio, enabling the system to scale down to a minimum flow of 12.0 ml\/h without sacrificing the precision of the volumetric output.\u003c\/p\u003e \u003cp\u003eUtilising stepper motor technology and full stroke operation, the hydraulic assembly ensures accurate handling of even viscous or degassing liquids. FlowControl continuously monitors 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 dosing head and a durable PTFE diaphragm designed for long-term service. Connectivity is a core feature, with communication functions available according to the selected control variant. The assembly handles liquid temperatures up to 45°C and includes two potential-free output relays for system alarms or stroke signals.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\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 allows precise adjustment from 12.0 L\/h down to 12.0 ml\/h.\u003c\/li\u003e \u003cli\u003eStepper motor technology provides smooth and continuous dosing.\u003c\/li\u003e \u003cli\u003ePVDF dosing head, PTFE diaphragm and ceramic double ball valves for chemical resistance.\u003c\/li\u003e \u003cli\u003eCommunication functions available according to the selected control variant.\u003c\/li\u003e \u003cli\u003eTwo potential-free output relays for system alarms or stroke count signalling.\u003c\/li\u003e \u003cli\u003eClick-wheel interface and graphical LC display simplify configuration and monitoring.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974841012471,"sku":"93243959","price":5343.09,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dda-12-10-autoflowadapt-digital-dosing-pump-chemical-dosing-flowcontrol.png?v=1785153911","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dda-12-10-autoflowadapt-digital-dosing-pump-chemical-dosing-flowcontrol","provider":"Foundation Pumps","version":"1.0","type":"link"}
