Product Overview
Higher throughput industrial dosing for process water treatment requiring precise chemical delivery from restrictive sources calls for the precise speed control of the DDA series. This configuration is optimised for automated environments where the pump must interact with external water meters and PLC systems via digital relay and analog signals.
Powered by a 24 W motor operating on 240v, the unit delivers a maximum dosing capacity of 17.0 L/h at a 7 bar maximum operating pressure. It achieves a 1000:1 turn-down ratio, which provides the wide dosing range needed to manage dosing rates from its peak flow down to a precise minimum of 17.0 ml/h.
The hydraulic design utilises advanced stepper motor technology to provide smooth and continuous dosing. The unit includes AR control functionality for manual, pulse, and analog modes, ensuring consistent performance with diverse installation requirements.
Structural durability is ensured by a rugged PVDF body, PTFE gaskets, and ceramic ball valves suitable for aggressive industrial fluids. The unit handles liquid temperatures up to 45°C and includes two potential-free output relays for alarms or integration with external control systems.
