Grundfos SMART Digital DDA-C Dosing Pump
Model: DDA 12-10 FCM-C-PV/T/C-F-31U2U2IG
Product Number: 93243959
Date: 29/07/2025
Product Overview
The SMART Digital DDA-C is a compact, positive-displacement diaphragm dosing pump. It features a variable-speed drive (stepper motor) and intelligent control electronics designed for minimum energy consumption.
The SMART Digital Dosing series operates at full stroke length, ensuring optimal accuracy, priming, and suction, even for high-viscosity or degassing liquids. The duration of the discharge stroke varies based on the set capacity, providing an optimal, uniform, and continuous discharge flow.
Installation is facilitated by a click-stop mounting plate, allowing placement in three different positions without additional accessories. The control cube can be rotated to the front, left, or right. Operation and commissioning are made intuitive through the click wheel and the multi-coloured backlit graphic plain-text LC display. Control elements are protected by a transparent cover.
The DDA-C offers built-in connectivity for easy setup and tracking via the Grundfos GO app, and seamless integration into Modbus RTU or TCP bus systems.
Dosing Head Components
- A durable and chemically resistant full PTFE diaphragm.
- Double ball valves for maximum dosing accuracy.
- A deaeration valve for easy start-up.
Operation Modes and Functions
- Manual dosing in ml/h, l/h, or gph.
- Pulse control in ml/pulse (includes memory function).
- Analog control, 0/4-20 mA (scalable).
- Pulse-based batch function in ml, l, or gal.
- Timer-based batch function (dosing timer cycle or week).
- Fieldbus control (integrated Modbus RTU and TCP; Profibus DP, Profinet and Ethernet IP via CIM/CIU models).
- Cloud control and monitoring (Smart Digital Chempairing Suite; Grundfos Connect).
Other Features
- Auto deaeration during pump standby to avoid stand-still due to air-locking.
- Two SlowMode steps (anti-cavitation), offering 50% and 25% maximum flow, suitable for high-viscosity or degassing liquids.
- Max. Capacity setting to limit the pump's output to a set maximum.
- Service information display shows when service is required and lists wear-part order numbers.
- Two-step key lock function to protect the pump against unauthorized access.
- Multi-parameter dashboard function to display information on up to 4 parameters.
- Counter for total dosed volume (resettable) and operating hours.
- Functionality to save, copy, and load customized settings, as well as reload factory settings.
Signal Inputs/Outputs
- Input for pulse, analog 0/4-20mA, and external stop signals.
- Input for low-level and empty-tank signals.
- Two potential-free output relays (max. 30 V AC/DC), configurable for functions such as alarm, stroke signal, pump dosing, or timer.
