Grundfos DDE Digital Diaphragm Dosing Pumps

Grundfos DDE Digital Diaphragm Dosing Pumps for Chemical Metering, Water Treatment, Disinfection, and Industrial Process Applications

Grundfos DDE Digital Diaphragm Dosing Pumps are compact SMART Digital dosing pumps designed for accurate chemical metering in water treatment, wastewater treatment, disinfection, industrial process water, and general chemical feed applications. The DDE range provides straightforward digital dosing technology for applications where dependable operation, easy adjustment, and cost-effective chemical injection are priorities.

The Grundfos DDE uses a variable-speed stepper motor to control dosing capacity. Rather than relying primarily on conventional stroke-length adjustment, the pump operates with full stroke length while changing motor speed to deliver the required dosing rate. This helps provide smooth, precise chemical feed across the pump's operating range while simplifying setup and operation.

The DDE is positioned as an entry-level solution within the Grundfos SMART Digital dosing pump family. Its compact design and simplified controls make it particularly useful for standard dosing applications that do not require the more advanced monitoring and process-control capabilities available with DDC or DDA pumps. Depending on the selected DDE configuration, dosing capacity can be adjusted directly from the pump using an intuitive control interface.
