Grundfos DMH
The Grundfos DMH range is a series of extremely strong, robust pumps for applications
requiring a reliable dosing and high-pressure capability, such as process engineering.
The Grundfos DMH 28x has been especially designed for high-pressure applications from 50 up to 200 bar.
The range is highly versatile: it covers a wide flow range and offers a variety
of dosing head sizes, materials and accessories. Customers worldwide have enjoyed years
of trouble-free operation from their DMH pumps.
DMH pumps have a very high dosing accuracy and allow an exact reproducibility.
For Grundfos DMH25x, the dosing flow fluctuation is <± 1.5 % within the 10-100 % control range, and the linearity deviation is ± 2 % of the full-scale value. For Grundfos DMH28x, the dosing flow fluctuation is <± 1.0 % within the 10-100 % control range, and the linearity deviation is ± 1 % of the full-scale value.
