Grundfos DDE 15-4 PR Pulse PTFE Smart Digital S Dosing Pump

The Grundfos DDE 15-4 PR Pulse PTFE Smart Digital S Dosing Pump is a compact electronic chemical dosing pump designed for accurate and reliable chemical injection in water treatment, fertigation, cooling water, process water and general dosing applications.

The DDE PR range is suited to installations where the pump needs to operate manually or respond to pulse input from a water meter, controller or external signal. This makes it a practical choice for proportional chemical dosing systems where dosing output needs to follow water flow or process demand.

The PR control variant includes manual and pulse operation modes, remote on/off functionality, chemical pre-empty and empty level inputs, plus digital relay outputs for alarm and low-level chemical signals.

This model features a PVC dosing head, PTFE gasket and ceramic valve balls. With its compact Smart Digital design, pulse-capable control and simple adjustment, the DDE 15-4 PR is well suited to automated chemical dosing systems requiring dependable metering and easy setup.
