Grundfos DDA 30-4 FCM-C PTFE Smart Digital S Dosing Pump

The Grundfos DDA 30-4 FCM-C PTFE Smart Digital S Dosing Pump is a high-accuracy digital chemical dosing pump designed for precise chemical injection in water treatment, wastewater treatment, fertigation, industrial process water, cooling water and general chemical dosing applications. With a maximum flow rate of 30 L/h and operating pressure up to 4 bar, it is suitable for high-capacity dosing applications requiring accurate and reliable chemical delivery.

As part of the Grundfos SMART Digital S range, this model uses stepper motor technology and full-stroke dosing for reliable performance across low and variable dosing rates. The FCM-C control variant includes FlowControl technology, which helps detect dosing faults such as air bubbles, pressure fluctuations and line interruptions while continuously monitoring pump performance. The durable full PTFE diaphragm, double ball valves and integrated deaeration valve further enhance dosing accuracy and operational reliability.

AutoFlowAdapt helps maintain the target dosing output when system conditions change, while manual, pulse, analogue, batch, timer and fieldbus operating modes provide flexibility for a wide range of installations. Setup and monitoring can be carried out through the pump interface or via the Grundfos GO app, with integrated Modbus RTU/TCP connectivity for seamless integration into industrial automation and building management systems.

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