    General chemical dosing tasks requiring a simplified control interface are served by this speed-controlled diaphragm system. This Smart Digital S configuration is intended for applications where reliable manual dosing and high hydraulic efficiency are the primary requirements, providing a cost-effective solution for standard liquid transfer.

    Driven by a 19 W motor, the unit operates on a 240v supply and delivers a maximum dosing capacity of 15.0 L/h at a 4 bar maximum pressure. It utilises a 1000:1 turn-down ratio, allowing the operator to adjust the output via a 0.1 - 100% scale knob for precise control over the dosing cycle.

    The hydraulic design features stepper motor technology that ensures smooth and continuous dosing. This model includes an auto deaeration function and handles liquids with viscosities up to 50 mPas, ensuring consistent performance with diverse industrial media.

    Mechanical integrity is provided by a PVC dosing head and a durable PTFE diaphragm paired with ceramic ball valves. The unit features an IP65 enclosure and handles liquid temperatures up to 45°C. It is supplied with an Australian power plug and standard hose connections for 4/6, 6/9, 6/12, and 9/12 mm tubing.
