    Process water reticulation and high-capacity chemical treatment require a dosing system that combines significant throughput with advanced signal feedback. This Smart Digital XL configuration is intended for automated environments where the pump must interact with external sensors and control protocols to ensure fluid handling stability.

    Operating on a 240v supply, the unit consumes 62 W of power while delivering a maximum dosing capacity of 120.0 L/h at a 7 bar maximum operating pressure. It features a turn-down ratio of 800:1, providing the hydraulic strength required to manage high-volume chemical injection while maintaining the ability to scale down to a minimum flow of 0.15 L/h.

    The hydraulic design utilises advanced stepper motor technology to provide smooth and continuous dosing. The AR control variant supports manual, pulse, and analog 0/4-20mA operation, incorporating two potential-free output relays for system alarms or integration with external control systems.

    Construction features a chemically resistant PVDF pump head paired with durable PTFE gaskets and ceramic ball valves to ensure compatibility with aggressive media. Housed in an IP65-rated enclosure, it is supplied with high-capacity U3 connection packs and handles liquid temperatures up to 50°C.

    FEATURES

    • AR control variant with manual, pulse and analog 0/4-20mA modes and potential-free relay outputs.
    • Internal auto deaeration in standby mode prevents gas locks with degassing chemicals.
    • 800:1 turn-down ratio from 120.0 L/h down to 0.15 L/h for high-volume precision.
    • Stepper motor technology provides smooth and continuous dosing.
    • PVDF pump head, PTFE gaskets and ceramic ball valves for aggressive chemical compatibility.
    • IP65 rated enclosure protects internal electronics in industrial environments.
    • U3 connection packs for standard 19/20 mm hose and 25 mm pipe systems.
    • Two potential-free output relays for system alarms or integration with external control systems.
