Product Overview
Bulk chemical dosing of specialised media like Fluorosilicic Acid requires a system that combines high-volume throughput with specialised material sensing. This configuration from the Smart Digital S range is specifically engineered with a Sapphire sensor to ensure safety and precision when handling FSA in water treatment networks at scale.
Powered by a 24 W motor, the unit produces a maximum flow rate of 30.0 L/h against a 4 bar maximum operating pressure. It utilises a 1000:1 turn-down ratio, allowing for consistent volumetric accuracy across a broad range of flow settings down to a minimum of 30.0 ml/h to match the available site chemical demand.
The hydraulic design centres on advanced stepper motor technology, providing smooth and continuous dosing. This model incorporates FlowControl to continuously monitor the dosing process, while AutoFlowAdapt automatically compensates for changes in process pressure to maintain accurate dosing.
Mechanical durability is provided by a PVDF pump head, PTFE gaskets, and the specialised Sapphire sensor for aggressive media. The unit includes communication functions available according to the selected control variant. It is rated for liquid temperatures up to 45°C and is housed in a robust IP65 enclosure.

What peak dynamic head elevation can this wastewater dosing assembly overcome?
Supporting high-throughput chemical addition, the DDA 30-4 develops a peak dynamic head of 40 m against 4 bar backpressure.
What maximum chemical flow volume in liters per minute does this wastewater unit deliver?
Transferring wastewater additives through 4, 6, 9, 12 mm connections, the Grundfos DDA 30-4 produces a maximum delivery flow rate of 0.5 L/Min (30.0 L/h).
How do the casing material and sapphire sensor construction defend against chemical attack?
Chemical fluid processing on the DDA-30-4 combines a durable PVDF dosing head and PTFE gaskets with a sapphire sensor for reliable dosing feedback in wastewater applications.
Across facility power lines, what electrical voltage feed and motor kilowatt power run this pump?
Driven by an efficient motor providing 0.024 kW (24 W), the Grundfos DDA 30 4 connects to 240 V facility power networks.
What operating pressure in bar and fluid temperature limit are certified for wastewater dosing?
Wastewater addition boundaries establish that the DDA 30-4 FCM-C-PVTT-F-31U7U7 manages working pressures up to 4 bar across temperatures up to 45 °C.
