This system is intended for users who need to move up to 200 litres per hour of process chemicals with a manual scale interface for simplified on-site operation.\u003c\/p\u003e \u003cp\u003ePowered 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 features an 800:1 turn-down ratio, allowing the system to operate at a minimum flow of 0.25 L\/h, providing the hydraulic strength required for large-scale dosing without complex signal requirements.\u003c\/p\u003e \u003cp\u003eThe hydraulic assembly utilises stepper motor technology to provide smooth and continuous dosing. This model prioritises ease of use via a front-mounted scale knob, ensuring that high-volume delivery is maintained with volumetric precision in daily service.\u003c\/p\u003e \u003cp\u003eStructural durability is ensured by a rugged PVC pump head and durable PTFE gaskets paired with ceramic ball valves for chemical compatibility. Housed in an IP65 enclosure, the unit handles liquid temperatures up to 40°C and is supplied with high-capacity U3 connection packs.\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 configuration.\u003c\/li\u003e \u003cli\u003eFull stroke operation maintains dosing accuracy under varying backpressure.\u003c\/li\u003e \u003cli\u003e800:1 turn-down range from 200.0 L\/h down to 0.25 L\/h for precise adjustment.\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 protects motor and electronics in industrial installations.\u003c\/li\u003e \u003cli\u003eU3 connection packs for high-capacity throughput with standard pipe systems.\u003c\/li\u003e \u003cli\u003e100-240v voltage compatibility for diverse site power supplies.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974842126583,"sku":"99246460","price":6702.63,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dde-200-4-scale-knob-control-digital-dosing-pump-chemical-dosing.png?v=1785153974","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dde-200-4-scale-knob-control-digital-dosing-pump-chemical-dosing","provider":"Foundation Pumps","version":"1.0","type":"link"}
