Process water disinfection requiring automated signal feedback calls for the precise speed control of the DDE XL series. This configuration is optimised for automated site infrastructure where the pump must interact with external water meters and PLC systems via digital relay and analog signals for sustained accuracy.
The unit is powered by a 62 W single-phase motor drawing power from a standard 240v supply. It delivers a maximum dosing capacity of 120.0 L/h at a 7 bar maximum operating pressure, utilising an 800:1 turn-down ratio to scale performance accurately down to a minimum flow of 0.15 L/h to match available demand.
The hydraulic design utilises advanced stepper motor technology to provide smooth and continuous dosing. This AR control variant includes pulse input, 4-20mA control, and two potential-free output relays, ensuring the unit can be fully synchronised with complex site process automation.
Structural durability is ensured by a rugged PVC pump head and durable PTFE gaskets paired with ceramic ball valves. Connectivity is managed via manual adjustment or digital signals, and the unit includes a front-mounted scale knob. Housed in an IP65 enclosure, it handles liquid temperatures up to 40°C and includes U3 connection packs.
