DDA is an advanced digital dosing pump

DDA is a digital dosing pump for complex and demanding applications where the focus is on maximum process reliability. The intuitive graphical user interface gives you easy access to a wide range of highly advanced functions and features. With a powerful variable-speed stepper motor and a turn-down ratio of up to 1:3000, the DDA dosing pump ensures smooth, continuous and ultra-precise dosing in any application that requires chemical treatment and/or conditioning of media.

FlowControl detects any issues in your DDA dosing pump

DDA-FC and DDA-FCM feature the FlowControl system, which detects overpressure, line bursts and air bubbles in the dosing head and suction-side cavitation. 

DDA-FCM features FLOWADAPT, which ensures that your dosing accuracy is maintained even when system pressure fluctuates.

With the built-in dosing timer, you can set up batch dosing either as a simple repeating cycle or for up to 16 procedures over the course of a week.

The automatic deaeration function stops air bubbles from building in the dosing head so your dosing process does not stop due to air-locking.
