When it comes to conventional applications, the diaphragm dosing pump DDC with clever control electronics and a speed-controlled stepper motor drive is utilized for the automated, continuous, or intermittent dosing of non-outgassing chemicals. When dosing, the dosing pump always runs at full stroke length for optimal accuracy. Even at low dosage volume flows, low-pulsation and continuous dosing are made possible by the stepper motor drive.


Voltage 100 - 240 V
Frequency 50 - 60 Hz
Protection class IP 65
Conditions of use Can be used for dosing liquid, non-gassing active substances. Resistance of the materials to the chemicals used must be checked.
Ambient temperature 0 – 45 °C
Temperature Dosing medium -10 – 45 °C

Utilization of DDC Dosing Pumps For Standard Applications

  1. Standard dosing pump that is easy to use and has inputs and outputs for all common applications
  2. Ideal for a variety of general applications, such as biocide dosing or water-meter controlled dosing.
  3. Suitable for dosing in closed systems (high concentrations and low quantities)

Advantages of DDC Dosing Pumps For Standard Applications

  1. High precision since the pump always runs at full stroke length
  2. Due to a continuous suction stroke and a varied pressure stroke, the dosage is uniform and consistent.
  3. Longer service life as a result of fewer pressure peaks
  4. It is possible to administer precisely even very viscous medium (SlowMode).
