Digital DosingTM Pumps The SMART Digital generation DDA, DDC and DDE range of dosing or metering pumps with powerful variable-speed stepper motor brings state-of-the-art technology to perfection. Combined expert knowledge and the new patented solutions set future standards. Traditional technologies such as stroke length / stroke frequency adjustment with synchronous motor or solenoid drive become a thing of the past. Unique flexibility with only a few variants. The included click-stop mounting plate makes the new pump more flexible. Three different positions are possible without using any additional accessories, such as wall brackets. Service and pump exchange can now be done easily and fast just by clicking the pump in and out of the mounting plate. The control cube on the DDA and DDC pump can be lifted and turned easily into three different positions: front, left or right. A turn-down ratio of up to 1:3000, a wide supply voltage range (100-240 V; 50/60 Hz).
