Grundfos DMX
Electromechanical Dosing Pumps

Grundfos DMX

The Grundfos DMX range has proven its worth in dosing applications worldwide.
With their robust diaphragm-based design and their high-quality motors DMX pumps require
minimum maintenance and are best choice for many dosing applications.

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

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 – as much as necessary, as little as possible.
