Grundfos Diaphragm Dosing Pumps with 0/4–20mA Analogue Control

This collection features Grundfos speed-controlled diaphragm dosing pumps designed for integration with analogue input signals (0/4–20mA) from flow meters, pH controllers, PLCs, and other process instrumentation. Perfect for process-driven chemical dosing in water treatment, fertigation, industrial systems, and chemical manufacturing, these pumps offer responsive and accurate control based on real-time process conditions.

Models in this collection include:

• Grundfos DDA-AR – With analogue control and auto-deaeration functionality
• Grundfos DDA-FCM – Combines flow monitoring with analogue signal responsiveness
• Grundfos DME-AR – High-flow dosing with analogue control precision

These pumps adjust their dosing rate proportionally to incoming current signals, allowing full control over chemical feed rates in closed-loop systems. Benefits include improved process stability, reduced chemical waste, and easy integration into existing analogue infrastructures.

Each unit is built with Grundfos Digital Dosing™ technology, ensuring smooth, pulse-free dosing, superior reliability, and smart diagnostics.

All models come with free shipping Australia-wide and expert support from Land & Water Technology.
