This Smart Digital S variant is optimised for general service applications where precise speed control and a standard manual interface are the primary requirements.\u003c\/p\u003e \u003cp\u003ePowered by a 24 W motor operating on a 240v supply, the unit produces a maximum flow rate of 12.0 L\/h against 10 bar maximum backpressure. 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 12.0 ml\/h.\u003c\/p\u003e \u003cp\u003eThe hydraulic assembly features a spring-loaded valve configuration designed for improved handling of liquids with higher viscosities or those prone to degassing. Stepper motor technology ensures smooth and continuous dosing.\u003c\/p\u003e \u003cp\u003eMechanical durability is provided by a PVC dosing head and EPDM gaskets paired with ceramic ball valves. The unit includes AR control functionality for manual speed and pulse operation, housed in an IP65 enclosure. It is rated for liquid temperatures up to 45°C and includes two potential-free output relays for alarm signalling or integration with external control systems.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eSpring-loaded valve design for improved performance with viscous or degassing chemicals.\u003c\/li\u003e \u003cli\u003eAR control variant supports manual speed adjustment and pulse control in ml\/pulse.\u003c\/li\u003e \u003cli\u003e1000:1 turn-down ratio for adjustment from 12.0 L\/h down to 12.0 ml\/h.\u003c\/li\u003e \u003cli\u003eStepper motor drive provides smooth and continuous dosing.\u003c\/li\u003e \u003cli\u003ePVC pump head and EPDM gaskets for compatibility with standard industrial fluids.\u003c\/li\u003e \u003cli\u003eGraphical LC display with plain-text menu for simplified setup and operating status.\u003c\/li\u003e \u003cli\u003eIntegrated input for low-level and tank empty signals prevents dry-run damage.\u003c\/li\u003e \u003cli\u003eIP65 rated enclosure protects motor and electronics from dust and water spray.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974841438455,"sku":"93242911","price":3596.89,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dda-12-10-spring-loaded-valve-digital-dosing-pump-viscous-media-handling.png?v=1785153934","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dda-12-10-spring-loaded-valve-digital-dosing-pump-viscous-media-handling","provider":"Foundation Pumps","version":"1.0","type":"link"}
