    High-volume industrial water treatment and chemical dosing applications demand a configuration that provides high-capacity dosing with a simplified control interface. This Smart Digital XL system is engineered for industrial applications where the primary service requirement is consistent delivery of chemicals to storage systems and networks at high volumes.

    The unit is driven by a 62 W single-phase motor drawing power from a standard 240v supply to maintain high hydraulic efficiency. It delivers a maximum dosing capacity of 120.0 L/h at a 7 bar maximum operating pressure, utilising an 800:1 turn-down ratio to scale performance accurately down to a minimum flow of 0.15 L/h.

    The hydraulic design utilises advanced stepper motor technology to provide smooth and continuous dosing. This basic control model supports manual speed adjustment via a scale knob, supporting accurate dosing across the operating range.

    Mechanical integrity is maintained by a PVC pump head and PTFE gaskets paired with ceramic ball valves suitable for standard process media. Housed in an IP65 enclosure, it handles liquid temperatures up to 40°C and includes U3 connection packs for reliable industrial installation.

    FEATURES

    • Manual control via 0.15-100% scale knob for simple on-site dosing adjustment.
    • Full stroke operation maintains volumetric accuracy under varying backpressure.
    • 800:1 turn-down range from 120.0 L/h down to 0.15 L/h for precise control.
    • Stepper motor technology provides smooth and continuous dosing.
    • PVC pump head, PTFE gaskets and ceramic ball valves for standard chemical resistance.
    • IP65 rated enclosure for mechanical protection in industrial environments.
    • U3 connection packs for easy installation with standard pipe systems.
    • 100-240v voltage compatibility and 1.5 m cable for easy site integration.
