    Bulk chemical injection duties require the throughput capacity of the Smart Digital XL series. This configuration is optimised for large-scale applications that demand up to 200 litres per hour while maintaining the precise signal control and accuracy required for modern industrial automation.

    Driven by a 62 W motor, the pump achieves a maximum dosing capacity of 200.0 L/h at a 4 bar maximum operating pressure. It utilises an 800:1 turn-down ratio, enabling the system to precisely scale down to a minimum flow of 0.25 L/h without losing the accuracy of the volumetric output during demanding process cycles.

    The hydraulic assembly features stepper motor technology and full stroke operation, providing smooth and continuous dosing. The AR control functionality includes manual speed adjustment and ml/pulse control, ensuring consistent volumetric accuracy is maintained even as system backpressure varies across the site installation.

    Structural durability is ensured by a rugged PVDF dosing head and durable PTFE gaskets paired with ceramic ball valves for aggressive chemical compatibility. The assembly includes two potential-free output relays for signalling stroke or alarm status and features a front-mounted control panel. It handles liquid temperatures up to 50°C and is housed in an IP65 enclosure.
