Grundfos SMART Digital Dosing Pumps

The Grundfos SMART Digital Dosing Pumps (DDA, DDC and DDE) feature a powerful variable-speed stepper motor and  deliver unrivalled precision in water treatment, and chemical and process engineering; thanks to Grundfos’ state-of-the art Digital Dosing™ technology. 

Grudfos Alldos SMART digital dosing pumps
Grudfos Alldos SMART digital dosing pumps: DDA

All Grundfos SMART Digital Dosing Pump modes feature the following:

  • Turn down ratio of 1:300 for DDA 7.5-16 and 1:1000 for all other models.
  • Smooth continuous dosing
  • Full stroke-length
  • improved dosing head/valve design for dosing of degassing liquids
  • click-stop mounting plate for flexible instillation
  • Full PTFE diaphragm ensuring high reliability
  • wide range power supply 100-240V 50/60Hz


 Easy to operate and supervise; the SMART Digital’s Flow Monitor alerts you to failures in the dosing process, while the AutoCal function automatically recalibrates the pump in case of fluctuating system pressure. Grundfos Alldos SMART range is ideal for intelligent flow management and optimum efficiency.
