Grundfos DDA (XL)-AR Series Smart Digital Diaphragm Dosing Pump with Pulse Analogue Control

The Grundfos DME375-10AR is a high-performance SMART Digital diaphragm dosing pump designed for accurate and reliable chemical dosing in industrial, municipal, and water treatment applications. Utilising advanced Digital Dosing™ technology, the DME series delivers smooth, continuous, and highly precise chemical injection while maintaining constant 100% stroke length operation for superior dosing accuracy and improved handling of degassing chemicals.

Designed for larger-scale dosing systems, the DME375-10AR provides dosing capacities up to 375 litres per hour at pressures up to 10BAR, making it ideal for demanding applications including water treatment plants, wastewater facilities, cooling towers, process water systems, fertigation systems, and industrial chemical dosing installations.

The AR control variant supports pulse and analogue control functionality for integration with PLCs, SCADA systems, flow meters, and automated process control systems. The intelligent digital controller allows simple adjustment of dosing rates directly in litres per hour while offering batch, timer, manual, and proportional dosing modes for maximum operational flexibility.

The DME series also features adjustable slow mode operation for dosing high viscosity liquids up to 3000mPas, integrated calibration functionality, anti-cavitation performance, and an easy-to-use backlit LCD interface for simplified setup and operation.
