The SMART Digital DDA pump is a compact positive displacement diaphragm dosing device with an energy-efficient variable-speed stepper motor drive and intelligent electronics for control. It guarantees optimum accuracy, priming, and suction even with high viscosity or degassing liquids by operating at full stroke length. The discharge flow is smooth and continuous as the duration of each stroke varies according to the set capacity. Installation in three different positions is possible without additional accessories due to its click-stop mounting plate. Its control cube can be easily positioned in front, left or right, while the commissioning and operation are intuitive thanks to the click wheel and multi-coloured backlit graphical LC display. The control elements are protected by a transparent cover.
