The superior diaphragm dosing pump DDA, equipped with an intelligent control electronics and a speed-controlled stepper motor drive, is utilized for the automated, continuous, or intermittent dosing of chemicals that do not outgas. It has a feature for automatically venting. 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 DDA Dosing Pump For Demanding Applications

Premium dosing pump with a wider range of capabilities for demanding industrial uses
Ideal for a variety of general applications, such as biocide dosing or water-meter controlled dosing
Additionally appropriate for outgassing media like sodium hypochlorite
Appropriate for dosing in closed systems (low and high concentrations)

Advantages of DDA Dosing Pump For Demanding Applications

High precision since the pump always 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
It is possible to precisely administer even very viscous and gaseous material (Slow Mode, Auto Venting).
