Grundfos Diaphragm Dosing Pumps – Pulse-Activated by Water Meter

This collection features Grundfos diaphragm dosing pumps designed for automated chemical dosing via pulse-contact water meter input. Ideal for proportional dosing applications in water treatment, fertigation, industrial processes, and irrigation, these pumps adjust their dosing volume based on real-time water flow — ensuring accuracy, consistency, and process efficiency.

Compatible with water meters emitting pulse signals (e.g. 1 pulse per X litres), these models include:

• Grundfos DDE-PR / DDE-AR – Economical solutions for basic proportional control
• Grundfos DDA-AR – Advanced features with high accuracy and auto-deaeration
• Grundfos DME-AR – High-flow proportional dosing for large-scale operations

By delivering a precise amount of chemical with each incoming pulse, these pumps are ideal for flow-based dosing tasks where no external controller is required. Each model uses Grundfos Digital Dosing™ technology for smooth operation, minimal maintenance, and long-term reliability.
