Description
The DDE pump is economically reliable and provides all of the benefits needed in dosing technology such as a maximum turn-down ratio of 1000:1 (max flow 4 gph or 15 l/h) and 800:1 (max flow 52.8 gph or 200 l/h) and steady, consistent dosing.
These pumps deliver dosing at a rate given by utilizing scaling, which runs from 0.1-100%. Highly desirable features that maximizes performance including a basic pulse control, unfilled signal, and outside function that stops operations. Additionally, there is an optimizable analog input that is built in with the DDE pump.
