    Reliable chemical injection in standard industrial water systems requiring high-volume throughput calls for the specialised valve configuration of this XL series unit. This system is intended for applications where the requirement for up to 120 litres per hour is balanced with spring-loaded valves for improved priming and handling of non-aggressive chemicals.

    Driven by a 62 W single-phase motor drawing power from a standard 240v supply, the unit delivers a maximum dosing capacity of 120.0 L/h at a 7 bar maximum pressure. It achieves an 800:1 turn-down ratio, providing the hydraulic strength required to manage large-scale chemical injection while maintaining precise digital control.

    The hydraulic design utilises advanced stepper motor technology to produce smooth and continuous dosing that handles slightly viscous liquids effectively. The AR control variant includes pulse input, analog 0/4-20mA control, and two potential-free output relays, ensuring the unit can be fully synchronised with complex site process automation networks.

    Structural durability is ensured by a rugged PVC pump head and EPDM gaskets paired with ceramic ball valves suitable for standard industrial liquids. The unit handles liquid temperatures up to 40°C and is housed in a robust IP65 enclosure.

    FEATURES

    • Spring-loaded valve design for improved priming and handling of viscous liquids.
    • AR control variant with manual, pulse and analog 0/4-20mA modes and potential-free alarm relays.
    • 800:1 turn-down range from 120.0 L/h down to 0.15 L/h for precise adjustment.
    • Stepper motor technology provides smooth and continuous dosing.
    • PVC pump head, EPDM gaskets and ceramic ball valves for standard chemical resistance.
    • IP65 rated enclosure for durability in dusty or moisture-prone environments.
    • Two potential-free output relays for integration with external control systems or alarm signalling.
