Complete pre-assembled system with dosing pump, dosing tank, suction lance, dosing hose, and control cable for the storage and dosing of liquid active compounds in water-bearing systems. 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.

Utilization of DOS DDC Dosing Units

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

Advantages of DOS DDC Dosing Units

Impact-resistant, stable tank with side-mounted level markers
Excellent dosage accuracy since the pump constantly runs at full stroke length
Due to a continuous suction stroke and a varied pressure stroke, the dosage is uniform and consistent.
longer service life as a result of fewer pressure peaks
For more viscous media, use Slow Mode.
Includes extras including a cable, dosing hose, and suction lance.
