Product Overview
Maximum capacity within the standard DDA range for higher-volume chemical injection and industrial transfer duties. This system is intended for process users who require the maximum hydraulic capacity of the DDA series while maintaining precise signal control and alarm feedback.
Driven by a 24 W single-phase motor, the unit produces a maximum dosing capacity of 30.0 L/h at a 4 bar maximum pressure. It utilises a 1000:1 turn-down ratio, allowing the operator to adjust the output via the graphical LC display menu for precise control from the peak flow down to a minimum of 30.0 ml/h.
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.
Mechanical integrity is provided by a PVDF dosing head and durable PTFE gaskets paired with ceramic ball valves. Housed in an IP65 enclosure, it handles liquid temperatures to 45°C and includes two potential-free output relays for alarm signalling or integration with external control systems.
