When dosing non-outgassing chemicals automatically, continuously, or intermittently, the diaphragm dosing pump DDE for basic applications with a speed-controlled stepper motor drive and intelligent control electronics is utilized. 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 DDE Dosing Pumps For Basic Applications

An affordable dosage pump with simple features including manual operation
Ideal for a variety of general applications, such as biocide dosing or water-meter controlled dosing

Advantages of DDE Dosing Pumps For Basic 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
