Product Overview
Precision chemical management in water treatment and disinfection processes requires a system capable of handling aggressive media with accuracy. This digital dosing configuration is engineered for industrial chemical dosing applications where maintaining a precise chemical balance is essential for consistent dosing performance.
Operating on a standard 240v supply, the unit consumes 24 W of power while delivering a maximum dosing capacity of 7.5 L/h at a 16 bar maximum operating pressure. It features a 3000:1 turn-down ratio, allowing for smooth and continuous dosing even at flow rates as low as 0.0025 L/h.
The hydraulic design centers on advanced stepper motor technology, providing smooth and continuous dosing. This model incorporates FlowControl to continuously monitor the dosing process, while AutoFlowAdapt automatically compensates for changes in process pressure to maintain accurate dosing.
Construction features a chemically resistant PVDF pump head paired with durable PTFE gaskets and ceramic ball valves to ensure compatibility with a wide range of process liquids. Housed in an IP65-rated enclosure, communication functions are available according to the selected control variant.
