    Bulk chemical dosing of specialised media like Fluorosilicic Acid requires a system that combines high-volume throughput with specialised material sensing. This configuration from the Smart Digital S range is specifically engineered with a Sapphire sensor to ensure safety and precision when handling FSA in water treatment networks at scale.

    Powered by a 24 W motor, the unit produces a maximum flow rate of 30.0 L/h against a 4 bar maximum operating pressure. It utilises a 1000:1 turn-down ratio, allowing for consistent volumetric accuracy across a broad range of flow settings down to a minimum of 30.0 ml/h to match the available site chemical demand.

    The hydraulic design centres on advanced stepper motor technology, providing smooth and continuous dosing. This model incorporates FlowControl to continuously monitor the dosing process, while AutoFlowAdapt automatically compensates for changes in process pressure to maintain accurate dosing.

    Mechanical durability is provided by a PVDF pump head, PTFE gaskets, and the specialised Sapphire sensor for aggressive media. The unit includes communication functions available according to the selected control variant. It is rated for liquid temperatures up to 45°C and is housed in a robust IP65 enclosure.

    FEATURES

    • Sapphire sensor technology for accurate diagnostic dosing of Fluorosilicic Acid (FSA).
    • FlowControl monitors the dosing process and detects abnormal operating conditions.
    • AutoFlowAdapt automatically compensates for changes in process pressure to maintain accurate dosing.
    • 1000:1 turn-down ratio enables precise adjustment from 30.0 L/h down to 30.0 ml/h.
    • Stepper motor technology provides smooth and continuous dosing.
    • PVDF pump head, PTFE gaskets and ceramic ball valves for aggressive chemical resistance.
    • Communication functions available according to the selected control variant.
    • IP65 rated enclosure protects the unit in challenging site installations.
