This Smart Digital S configuration is intended for applications where reliable manual dosing and high hydraulic efficiency are the primary requirements, providing a cost-effective solution for standard liquid transfer.\u003c\/p\u003e \u003cp\u003eDriven by a 19 W motor, the unit operates on a 240v supply and delivers a maximum dosing capacity of 15.0 L\/h at a 4 bar maximum pressure. It utilises a 1000:1 turn-down ratio, allowing the operator to adjust the output via a 0.1 - 100% scale knob for precise control over the dosing cycle.\u003c\/p\u003e \u003cp\u003eThe hydraulic design features stepper motor technology that ensures smooth and continuous dosing. This model includes an auto deaeration function and handles liquids with viscosities up to 50 mPas, ensuring consistent performance with diverse industrial media.\u003c\/p\u003e \u003cp\u003eMechanical integrity is provided by a PVC dosing head and a durable PTFE diaphragm paired with ceramic ball valves. The unit features an IP65 enclosure and handles liquid temperatures up to 45°C. It is supplied with an Australian power plug and standard hose connections for 4\/6, 6\/9, 6\/12, and 9\/12 mm tubing.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eManual control via 0.1 - 100% scale knob for simple on-site dosing adjustment.\u003c\/li\u003e \u003cli\u003eIntegrated auto deaeration function prevents gas locks when dosing degassing chemicals.\u003c\/li\u003e \u003cli\u003e1000:1 turn-down ratio from 15.0 L\/h down to 0.015 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 diaphragm and ceramic ball valves for standard media compatibility.\u003c\/li\u003e \u003cli\u003eHandles liquids with viscosities up to 50 mPas.\u003c\/li\u003e \u003cli\u003eFull stroke operation maintains volumetric accuracy under varying backpressure.\u003c\/li\u003e \u003cli\u003eIP65 rated enclosure with Australian power plug and multiple hose connection options.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974841569527,"sku":"97721272","price":1174.58,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dde-15-4-scale-knob-control-digital-dosing-pump-chemical-dosing.png?v=1785153943","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dde-15-4-scale-knob-control-digital-dosing-pump-chemical-dosing","provider":"Foundation Pumps","version":"1.0","type":"link"}
