Grundfos DDA 120-7 AR PTFE Smart Digital XL Dosing Pump

The Grundfos DDA 120-7 AR PTFE Smart Digital XL Dosing Pump is a high-capacity, high-accuracy digital chemical dosing pump designed for precise chemical injection in municipal water treatment, wastewater treatment, industrial process water, cooling water, desalination and other demanding chemical dosing applications. With a maximum flow rate of 120 L/h and operating pressure up to 7 bar, it is ideal for large-scale dosing systems requiring exceptional accuracy, reliability and flexible process control.

As part of the Grundfos SMART Digital XL range, this model uses a high-efficiency brushless motor and full-stroke dosing technology to deliver smooth, continuous and highly accurate chemical dosing across a wide operating range. The AR control variant supports analogue, pulse and fieldbus control, making it suitable for integration into automated dosing systems. The durable full PTFE diaphragm, ceramic valve balls and integrated deaeration valve provide excellent dosing accuracy, reliable priming and dependable operation, even with high-viscosity or degassing liquids.

Auto deaeration helps prevent air locking during standby, while manual, pulse, analogue, batch, timer and fieldbus operating modes provide maximum flexibility for demanding installations. Setup and monitoring can be carried out through the intuitive pump interface, with integrated GENIbus communication allowing seamless connection to SCADA and industrial automation systems via Grundfos CIU fieldbus modules.

This model features a PVDF dosing head, PTFE gasket and ceramic valve balls, making it suitable for a wide range of aggressive chemical dosing applications, subject to chemical compatibility.
