Grundfos DMH hydraulically actuated piston dosing pumps have a dosing range of 0.15l/hour to 2 x 1500 l/hour.
And a maximum pressure range from 200 bar to 40 bar.
DMH pumps can offer accuracy of <+/- 1.5% within its 10 - 100% control range.
Pumps offer smooth low pulsing dosing.
Motors can be supplied 50hz 60hz and 100hz via frequency converter.
EX and ATEX versions are also available.
System over pressurisation risk is reduced due to the pumps pressure releif valve and active diaphragm protection system. A degasssing valve can also be used.
