The smart digital DDE dosing pump from Grundfos has a variable speed drive ( Stepper motor) and intelligent electronics with minimum energy consumption.

The DDE is the cost-effective entry-level model with a maximum turn-down ratio of 1:1000 and smooth, continuous dosing. This one model can replace a whole host of existing models with dosing rates ranging from 0.006 to 6 l/h. The rate is set using a logarithmic scale that runs from 0.1-100 %. The model’s straightforward pulse control, external stop function and empty level signal are ideal for basic OEM applications.
