This configuration is optimised for large-scale applications that demand up to 200 litres per hour while maintaining the precise signal control and accuracy required for modern industrial automation.\u003c\/p\u003e \u003cp\u003eDriven by a 62 W motor, the pump achieves a maximum dosing capacity of 200.0 L\/h at a 4 bar maximum operating pressure. It utilises an 800:1 turn-down ratio, enabling the system to precisely scale down to a minimum flow of 0.25 L\/h without losing the accuracy of the volumetric output during demanding process cycles.\u003c\/p\u003e \u003cp\u003eThe hydraulic assembly features stepper motor technology and full stroke operation, providing smooth and continuous dosing. The AR control functionality includes manual speed adjustment and ml\/pulse control, ensuring consistent volumetric accuracy is maintained even as system backpressure varies across the site installation.\u003c\/p\u003e \u003cp\u003eStructural durability is ensured by a rugged PVDF dosing head and durable PTFE gaskets paired with ceramic ball valves for aggressive chemical compatibility. The assembly includes two potential-free output relays for signalling stroke or alarm status and features a front-mounted control panel. It handles liquid temperatures up to 50°C and is housed in an IP65 enclosure.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eAR control variant with manual speed adjustment, ml\/pulse control and potential-free relay outputs.\u003c\/li\u003e \u003cli\u003eLow-level and tank empty signal inputs protect against dry-run damage.\u003c\/li\u003e \u003cli\u003e800:1 turn-down range from 200.0 L\/h down to 0.25 L\/h for precise control.\u003c\/li\u003e \u003cli\u003eStepper motor drive with full stroke operation for 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\u003eFront-mounted control panel for convenient on-site configuration.\u003c\/li\u003e \u003cli\u003eTwo potential-free output relays for stroke or alarm status signalling.\u003c\/li\u003e \u003cli\u003eIP65 rated enclosure for durability in challenging industrial environments.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974841897207,"sku":"99246431","price":10077.98,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dda-200-4-ar-control-digital-dosing-pump-water-treatment.png?v=1785153960","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dda-200-4-ar-control-digital-dosing-pump-water-treatment","provider":"Foundation Pumps","version":"1.0","type":"link"}
