Product Overview
Higher throughput industrial dosing for process water treatment requiring precise chemical delivery from restrictive sources calls for the precise speed control of the DDA series. This configuration is optimised for automated environments where the pump must interact with external water meters and PLC systems via digital relay and analog signals.
Powered by a 24 W motor operating on 240v, the unit delivers a maximum dosing capacity of 17.0 L/h at a 7 bar maximum operating pressure. It achieves a 1000:1 turn-down ratio, which provides the wide dosing range needed to manage dosing rates from its peak flow down to a precise minimum of 17.0 ml/h.
The hydraulic design utilises advanced stepper motor technology to provide smooth and continuous dosing. The unit includes AR control functionality for manual, pulse, and analog modes, ensuring consistent performance with diverse installation requirements.
Structural durability is ensured by a rugged PVDF body, PTFE gaskets, and ceramic ball valves suitable for aggressive industrial fluids. The unit handles liquid temperatures up to 45°C and includes two potential-free output relays for alarms or integration with external control systems.
FEATURES
- AR control variant with manual speed adjustment, pulse-based operation and analog 0/4-20mA control.
- Low-level and empty-tank signal inputs protect the pump from dry-run damage.
- 1000:1 turn-down ratio for precise adjustment from 17.0 L/h down to 17.0 ml/h.
- Stepper motor technology provides smooth and continuous dosing.
- PVDF dosing head, PTFE gaskets and ceramic ball valves for aggressive fluid resistance.
- Batch and timer operating modes for flexible site process automation.
- Two potential-free output relays for alarms or integration with external control systems.
- IP65 rated enclosure protects internal components in industrial environments.

How is the motor power rated in kilowatt and what electrical voltage feed powers this drive?
Energy delivery to the DDA 17-7 is managed by a compact motor rated at 0.024 kW (24 W) operating on 240 V.
What operating pressure in bar and process liquid temperature limit govern this dosing system?
Industrial fluid service permits the Grundfos DDA 17-7 to reach working pressures up to 7 bar with chemical temperatures up to 45 °C.
What peak dynamic head elevation is certified for this industrial dosing system?
Supplying steady reagent injection, the DDA-17-7 reaches a maximum dynamic head rating of 70 m at 7 bar.
What peak delivery flow capacity in liters per minute can be discharged through the dosing outlet?
Connecting into dosing networks via 4, 6, 9, 12 mm interfaces, the Grundfos DDA 17 7 provides a peak delivery flow rate of 0.28 L/Min (17.0 L/h).
What durable polymer material and wetted construction ensure resistance to chemical attack?
Fluid handling longevity on the DDA 17-7 AR-C-PVTC-F-31U2U2IG is governed by a PVDF dosing head and PTFE gaskets with AR control supporting pulse and 0/4-20mA automation inputs.
