This pulse-capable Smart Digital S system is engineered for applications where maintaining a precise dosing volume relative to external flow signals is the primary service requirement.\u003c\/p\u003e \u003cp\u003eThe unit is driven by a 19 W motor drawing power from a standard 240v supply to maintain high hydraulic efficiency. It delivers a maximum dosing capacity of 15.0 L\/h at a 4 bar maximum operating pressure, utilising a 1000:1 turn-down ratio to scale performance accurately down to a minimum flow of 0.015 L\/h for sensitive chemical balance.\u003c\/p\u003e \u003cp\u003eThe hydraulic design utilises stepper motor technology to provide smooth and continuous dosing. This model supports manual speed adjustment via a scale knob alongside pulse and remote On\/Off modes, 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. The unit features an IP65 enclosure and includes potential-free output relays for alarm or low-level status. It handles liquid temperatures up to 45°C and is supplied with an Australian power plug and 1.5 m cable.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eIntegrated pulse input for automated chemical injection synchronised with external flow signals.\u003c\/li\u003e \u003cli\u003eRemote On\/Off operation for integration with external control equipment.\u003c\/li\u003e \u003cli\u003eLow-level and tank empty signal inputs protect the pump from dry-run damage.\u003c\/li\u003e \u003cli\u003e1000:1 turn-down range 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\u003eManual adjustment via 0.1-100% scale knob for simple on-site configuration.\u003c\/li\u003e \u003cli\u003eTwo potential-free output relays for remote monitoring of alarms and chemical storage levels.\u003c\/li\u003e \u003cli\u003eIP65 rated enclosure with Australian power plug and 1.5 m cable.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974841667831,"sku":"98147447","price":1438.97,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dde-15-4-pulse-control-digital-dosing-pump-water-treatment.png?v=1785153947","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dde-15-4-pulse-control-digital-dosing-pump-water-treatment","provider":"Foundation Pumps","version":"1.0","type":"link"}
