Grundfos 99159439 SMART Digital Diaphragm Metering Pump DDE 120-7 AR-SS/T/SS-F-31A3A3B
Product number: 99159439
EAN Number: 5712607842277
SMART Digital diaphragm metering pump with stepper motor drive for low-pulsation and continuous metering. Variant reduction thanks to stepper motor already in the ECO version. The SMART Digital DDE 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 metering pump series always operates with full stroke length to ensure optimum accuracy and optimal filling of the dosing head, even with outgassing liquids. 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 manual dosing quantity, dosing quantity per pulse or analogue signal/dosing quantity ratio can be set with an adjustment wheel on a logarithmic scale from 0.1 to 100 %. The operating elements are protected by a transparent cover.
