SMART Digital diaphragm dosing pump with internal stepper motor drive. Economic Digital Dosing even for basic dosing applications (Digital Dosing Essential).

The SMART Digital DDE is a compact positive displacement, diaphragm dosing pump with variable-speed drive (stepper motor) and intelligent control electronics with minimum energy consumption. The SMART Digital Dosing series operates at full stroke length to ensure optimum accuracy, priming and suction, even for degassing liquids. The duration of each discharge stroke varies according to the capacity set, resulting in optimum smooth and continuous discharge flow. The click-stop mounting plate allows installation in three different positions without using any additional accessories. The dosing flow can be adjusted by means of an adjustment knob on a logarithmical scale from 0.1-100%.

The dosing head is composed of:

  • Long lifetime and universal chemical resistant Full-PTFE diaphragm.
  • Double ball valves for the highest dosing accuracy.
  • Deaeration valve for easy start-up.

Operation modes:

  • Manual dosing from 0.1 to 100%.

Other features:

  • Mechanical lock to protect the pump against unauthorised access.
