The SMART Digital DDA is a compact positive displacement, diaphragm dosing pump with variable speed drive (stepper motor) and intelligent control electronics with minimum energy consumption. The SMART Digital Dosing Series operates at full stroke length to ensure optimum accuracy, priming and suction, even for high viscosity or degassing liquids. The duration of each discharge stroke varies according to the capacity set, resulting in optimum smooth and continuous discharge flow. The click stop mounting plate allows installation in three different positions without using any additional accessories. The control cube can be turned easily into front, left or right position. The click wheel and the multi-colored backlit graphical, plain text LC display make commissioning and operation intuitive. The control elements are protected by a transparent cover.
