  • Description

    Grundfos pumps DMX range is highly versatile because it covers a wide flow range and offers a variety of dosing head sizes, materials and accessories.

    DMX mechanical diaphragm pumps offer accurate dosing with minimum maintenance.

    Accurate dosing – all the time

    The diaphragm design ensures that the dosing flow variation is below ± 1.5 % and the linearity deviation is kept below 4 % at all times. This allows very precise dosing of your chemicals

    Smooth and low-pulsation dosing

    Grundfos pumps DMX series ensures smooth and low-pulsation dosing without pressure peaks. This means less stress to all system components and therefore longer service intervals for the entire system.
