Diaphragm pump – DMX
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.
