DOSING PUMP GRUNDFOS DDC 6-10 AR-PP/E/C-F-31U2U2FG

SMART Digital DDC is a compact membrane pump for dosing, equipped with speed control (stepper motor) and intelligent control electronics with minimal energy consumption. The dosing head consists of the following components: - Long-lasting, fully PTFE-made membrane resistant to common chemicals. - Double ball valves ensure optimal dosing accuracy. - Air vent valve ensures easy commissioning. Operating modes: - Manual dosing, unit ml/h, I/h or gph. - Pulse control, unit ml/pulse (with built-in memory function). - Analog control 0/4-20 mA. Signal inputs/outputs: - Pulse input, analog 0/4-20 mA, external stop. - Low level and empty tank signal input. - Two potential-free relay outputs, max. 30 V AC/DC (configurable, e.g., alarm, pulse signal, pump dosing, etc.).
