DMH Dosing Pump Range

DMH Dosing Pump Range

DMH HYDRAULICALLY ACTUATED PISTON DIAPHRAGM DOSING PUMPS FROM 0.15 L/H UP TO 2 X 1500 L/H, WITH A PRESSURE RANGE FROM 200 TO 4 BAR

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 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.

Accurate dosing - all the time

DMH pumps have a very high dosing accuracy and allow an exact reproducibility. For 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 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.

Smooth and low-pulsation dosing

The DMH range combines sophisticated drive technolo gy and gear kinematics to ensure smooth and low-pulsation dosing without pressure peaks. This means less stress to all system components, such as tubes and valves
