Product Description

SMART Digital Dosing Pumps

Chemistry in water treatment, water and wastewater recycling and disinfection has experienced a huge development during the last years. This poses a challenge for today's dosing technology. More and more complex applications require intelligent dosing pumps with new drives or new controls and adjustment mechanisms to simplify the operators' job.

SMART Digital dosing pumps meet these challenges. They offer state-of-the-art drive technology, new dimensions of user-comfort and intelligent flow control. These features ensure extremely reliable, cost-effective and high-precision processes at an optimum price-performance ratio.

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 patented sensor technology to measure and verify flow, in addition to pressure monitoring. The AutoFlowAdapt feature on the FCM version can will correct the actual feed rate to match the pump's set point. 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.

  • Scalable control input signals (up to 1:3000 turndown ration) to meet the widest flow rates in one model.
  • Slow mode to improve the max viscosity up to 2500 CPS
  • Profibus ready (field retrofittable)
  • Three variants allow for different degrees of monitoring & control
DDA AR Automatic or manual control with a relay outputs
DDA FC AR + Flow Control for flow verification
DDA FCM FC + measurement to verify and measure flow. Pump will auto-adapt so actual feed rate matches target feed rate.


  • Same DDA intuitive click-wheel operation and a graphic LC display in more than 25 languages.
  • Slow mode to improve the max viscosity up to 2500 CPS
  • Direct feed rate setting in GPH or l/hr
  • Simple calibration mode
DDC A            Automatic or manual control
DDC AR            A + relay output



  • Low cost option for stepper motor driven metering pump.
  • 1:1000 turndown for smooth, continuous dosing and minimized pulsation.
  • Logarithmic scale on control knob that adjusts the feedrate from 0.1-100 %.
DDE B         Basic manual control
DDE P         B + pulse control
DDE PR         P + relay output
