This specific DDA FCM-C configuration is engineered with a Sapphire sensor to meet the unique monitoring requirements of aggressive chemical applications that standard sensors cannot accommodate.\u003c\/p\u003e \u003cp\u003eThe unit operates with a 24 W power input and delivers 7.5 L\/h at a 16 bar maximum pressure rating. It achieves a wide turn-down ratio of 3000:1, providing the torque and speed control necessary to manage dosing rates from its maximum capacity down to a precise minimum of 0.0025 L\/h for sensitive process control.\u003c\/p\u003e \u003cp\u003ePrecision is maintained through stepper motor technology and FlowControl measurement. AutoFlowAdapt automatically compensates for changes in process pressure to maintain accurate dosing.\u003c\/p\u003e \u003cp\u003eConstruction includes a PVDF head, PTFE gaskets, and a specialised Sapphire sensor for FSA compatibility. Control and connectivity are managed via communication functions available according to the selected control variant. The unit is rated for liquids up to 45°C and features an IP65 enclosure for industrial placement.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eSpecialised Sapphire sensor for accurate and safe dosing of Fluorosilicic Acid (FSA).\u003c\/li\u003e \u003cli\u003eFlowControl with Sapphire sensor monitors the dosing process and detects abnormal operating conditions.\u003c\/li\u003e \u003cli\u003eAutoFlowAdapt automatically compensates for changes in process pressure to maintain accurate dosing.\u003c\/li\u003e \u003cli\u003e3000:1 turn-down ratio enables precise control from 7.5 L\/h down to 0.0025 L\/h.\u003c\/li\u003e \u003cli\u003eStepper motor technology provides smooth and continuous dosing.\u003c\/li\u003e \u003cli\u003ePVDF housing and PTFE wetted parts for compatibility with aggressive chemicals.\u003c\/li\u003e \u003cli\u003eCommunication functions available according to the selected control variant.\u003c\/li\u003e \u003cli\u003ePotential-free output relays for configurable alarm signalling and integration with external control systems.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50974841110775,"sku":"93297795","price":6914.77,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-dda-7-5-16-sapphire-sensor-digital-dosing-pump-fluorosilicic-acid-dosing.png?v=1785153917","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-dda-7-5-16-sapphire-sensor-digital-dosing-pump-fluorosilicic-acid-dosing","provider":"Foundation Pumps","version":"1.0","type":"link"}
