The pump of the DMH series is a versatile positive displacement diaphragm dosing pump.
The diaphragm is coupled hydraulically via a precise gear-eccenter-tapet-system to a high efficiency AC motor. The dosing capacity is adjusted by varying the stroke length at the stroke adjustment knob in the ratio 1 to 10.
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.
The Grundfos DMH range is a series of extremely strong, robust pumps for applications requiring reliable dosing capability, such as process engineering. The DMH 28x models have been designed especially for high-pressure applications from 50 up to 200 bar.
The liquid end is composed of:
