This Smart Digital S unit is intended for properties that require the flexibility of manual adjustment combined with digital pulse and relay outputs for integration with external control systems.\u003c\/p\u003e \u003cp\u003eDriven by a 24 W motor, the pump produces a maximum flow rate of 12.0 L\/h against a 10 bar maximum backpressure. It utilises a 1000:1 turn-down ratio, allowing the system to precisely scale down to a minimum flow of 12.0 ml\/h, ensuring consistent volumetric output even during low-demand process cycles.\u003c\/p\u003e \u003cp\u003eThe hydraulic assembly utilises a stepper motor to produce smooth and continuous dosing. The inclusion of chemical pre-empty and empty level inputs prevents the system from running dry, while the potential-free output relays provide immediate signalling for alarms or stroke counts.\u003c\/p\u003e \u003cp\u003eStructural durability is provided by a PVDF dosing head and PTFE gaskets designed for aggressive chemical compatibility. The assembly is rated for liquid temperatures up to 45°C and features an IP65 enclosure. It 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\u003eAR control variant supports manual, pulse and analog 0\/4-20mA operation with potential-free alarm relays.\u003c\/li\u003e \u003cli\u003eInputs for chemical pre-empty and empty level signals to prevent dry-run damage.\u003c\/li\u003e \u003cli\u003e1000:1 turn-down range from 12.0 L\/h down to 12.0 ml\/h for precise adjustment.\u003c\/li\u003e \u003cli\u003eStepper motor ensures smooth and continuous dosing.\u003c\/li\u003e \u003cli\u003ePVDF dosing head and PTFE gaskets for compatibility with aggressive process media.\u003c\/li\u003e \u003cli\u003eGraphical LC display with plain-text menu for configuration and operating status.\u003c\/li\u003e \u003cli\u003eTwo potential-free output relays for alarm signalling or integration with external control systems.\u003c\/li\u003e \u003cli\u003eIP65 rated enclosure protects internal components from dust and water ingress.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974841307383,"sku":"93242930","price":3975.18,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dda-12-10-ar-control-digital-dosing-pump-chemical-dosing.png?v=1785153928","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dda-12-10-ar-control-digital-dosing-pump-chemical-dosing","provider":"Foundation Pumps","version":"1.0","type":"link"}
