ReefRun G2 DC Pump Range (4000 / 6000 / 8000 / 12000)

The next generation of Red Sea’s smart, silent and ultra-efficient return pumps — fully ReefBeat-enabled and engineered for flawless, modern reefkeeping.

The ReefRun G2 DC Pump series delivers silent, powerful and intelligent return pumping for any reef system. Using advanced Sine Wave motor technology, each model offers whisper-quiet operation with impressive output and precision control. Seamlessly integrated with the ReefBeat App (via the optional ReefRun Dual Controller), these pumps unlock automated schedules, Quick Actions, safety alerts, and even wave-pump functionality for closed-loop installations.

Built for reliability, flexibility and user-friendly operation, every ReefRun G2 pump includes a rotatable outlet, air-guard inlet guide, easy-access impeller housing and long-reach cable. Whether you’re running a compact reef or a high-demand system, the ReefRun G2 delivers consistent performance with industry-leading efficiency.
