Grundfos DME Digital Dosing pumps combine perfect precision with user-friendlyness, covering large dosing quantities in the range from 375 l/h to 940 l/h with few variants.

The operator can easily install and set the pump to dose exactly the quantity of dosing medium required in the application. In the display, the setting of the pump is read out directly in ml/h or l/h, pulse or batch, and the operation mode is easily identified by means of icons.

Turndown ratio 1:800, with a turndown ratio ten times better than that of traditional equipment, DME Digital Dosing pumps offer maximum flexibility and accuracy.

A unique drive and microprocessor control ensure that the medium is dosed precisely and with low pulsation, even if the pump is operating with high-viscosity or degassing media. Instead of the conventional stroke-length adjustment, the capacity of the DME is regulated by automatic adjustment of the motor speed during the discharge stroke and by fixed suction stroke speed, ensuring optimal and uniform mixing.

Turndown of the suction stroke to 75 %, 50 % or 25 % of the maximum speed ensures optimal priming and displacement of even the most difficult liquids.

Available with Profibus interface to supply performance data and status information for quality control, preventive maintenance and future reference

Built-in overload protection monitors the counterpressure of the pump and protects it against too high pressure loads.

The switch-mode power supply makes sure that Grundfos DME Digital Dosing pumps can be used worldwide within the 100-240 VAC – 50/60 Hz range.
