Overview

Overview

Grundfos’ SMART Digital range of dosing pumps delivers unrivalled precision in water treatment, and chemical and process engineering; thanks to Grundfos’ state-of-the art Digital Dosing™ technology. The micro-controlled stepper motor drives a turn-down ratio of up to 3000:1, which combined with continuous full stroke length displacement, accurate, smooth and continuous dosing is guaranteed at all times. Easy to operate, easy to supervise 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. For intelligent flow management and optimum efficiency, get SMART.

Tried and tested Digital Dosing™ solution

Available since 2010, the Grundfos SMART Digital dosing pump range is known for its state of the art monitoring features that ensure dependable, safe, and economical dosing operations, and for its industry-leading accuracy.

The range is available in two size categories:  

  • SMART Digital S (dosing flow up to 120 l/h, pressure up to 16 bar, turn-down ratio up to 1:3000)
  • SMART Digital XL (dosing flow up to 200 l/h, pressure up to 10 bar, turn-down ratio up to 1:800)

The SMART Digital S DDA, DDC, and DDE and the SMART Digital XL DDA and DDE are all based on tried and tested Digital Dosing™ technology from Grundfos. They offer powerful, variable-speed motors, a universal power supply, and a full-PTFE diaphragm that meets the most demanding requirements for chemical resistance and durability. The pumps open up a broad range of dosing applications.

DDA

The DDA model is the pump for complex and demanding applications where the focus is on maximum process reliability. In addition to an extended capacity range and a turn-down ratio of up to 1:3000, it boasts FlowControl, pressure monitoring, AutoFlowAdapt and integrated flow measurement. The package for industrial applications is rounded off by additional operating modes such as a week dosing timer and new functions such as auto deaeration.

DDC

The DDC impresses with features such as simple, intuitive click-wheel operation and a graphic LC display in more than 25 languages. What's more, all standard modes of operation and inputs/outputs such as analog control or output relay can be integrated into control systems. This pump is suitable for universal use thanks to highlights including the SlowMode (anti-cavitation) function for highly viscous media and the straightforward calibration mode.

DDE

The DDE is the cost-effective entry-level model with all the benefits of Digital Dosing such as 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.
