    Grundfos metering pump DDA 120-7 AR-SS/T/SS-F-31A1A1F

    Product number: 99159390

    EAN number: 5712607841782


    The SMART Digital DDA is a compact positive displacement diaphragm metering pump with variable speed drive (ECM motor) and an adjustment range of up to 1: 800. The SMART Digital dosing pump series always operates at full stroke length to ensure optimum accuracy and optimal filling of the dosing head, even with outgassing media. The duration of each pressure stroke varies according to the set dosing quantity, resulting in low-pulsation and quasi-continuous dosing operation. The click-on mounting plate facilitates installation and service. The operating cube can be conveniently mounted at the front, left or right. The rotary/push wheel and the multicoloured, backlit LCD graphic display with plain text display enable intuitive operation. The operating elements are protected by a transparent cover.
