This Smart Digital XL system is engineered for industrial applications where the primary service requirement is consistent delivery of chemicals to storage systems and networks at high volumes.\u003c\/p\u003e \u003cp\u003eThe unit is driven by a 62 W single-phase motor drawing power from a standard 240v supply to maintain high hydraulic efficiency. It delivers a maximum dosing capacity of 120.0 L\/h at a 7 bar maximum operating pressure, utilising an 800:1 turn-down ratio to scale performance accurately down to a minimum flow of 0.15 L\/h.\u003c\/p\u003e \u003cp\u003eThe hydraulic design utilises advanced stepper motor technology to provide smooth and continuous dosing. This basic control model supports manual speed adjustment via a scale knob, supporting accurate dosing across the operating range.\u003c\/p\u003e \u003cp\u003eMechanical integrity is maintained by a PVC pump head and PTFE gaskets paired with ceramic ball valves suitable for standard process media. Housed in an IP65 enclosure, it handles liquid temperatures up to 40°C and includes U3 connection packs for reliable industrial installation.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eManual control via 0.15-100% scale knob for simple on-site dosing adjustment.\u003c\/li\u003e \u003cli\u003eFull stroke operation maintains volumetric accuracy under varying backpressure.\u003c\/li\u003e \u003cli\u003e800:1 turn-down range from 120.0 L\/h down to 0.15 L\/h for precise control.\u003c\/li\u003e \u003cli\u003eStepper motor technology provides smooth and continuous dosing.\u003c\/li\u003e \u003cli\u003ePVC pump head, PTFE gaskets and ceramic ball valves for standard chemical resistance.\u003c\/li\u003e \u003cli\u003eIP65 rated enclosure for mechanical protection in industrial environments.\u003c\/li\u003e \u003cli\u003eU3 connection packs for easy installation with standard pipe systems.\u003c\/li\u003e \u003cli\u003e100-240v voltage compatibility and 1.5 m cable for easy site integration.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974842093815,"sku":"99246459","price":6203.12,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dde-120-7-scale-knob-control-digital-dosing-pump-process-chemical-dosing.png?v=1785153972","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dde-120-7-scale-knob-control-digital-dosing-pump-process-chemical-dosing","provider":"Foundation Pumps","version":"1.0","type":"link"}
