Product Description
Red Sea ReefRun G2 4000 DC Pump
The Red Sea ReefRun G2 4000 DC Pump is a compact smart-ready DC return pump for saltwater and freshwater aquariums, offering quiet sine-wave motor operation, adjustable 530-1060 GPH flow and optional ReefBeat ecosystem control through the Red Sea ReefRun Dual DC Pump Controller.
Compact ReefRun G2 Return Flow for Smaller Systems
The ReefRun G2 4000 is the entry model in Red Sea's next-generation ReefRun G2 pump family, making it a strong fit for smaller sump-based aquariums that need reliable return flow without oversizing the pump. It can run independently with the included flow controller or be integrated into Red Sea's ReefBeat system when paired with the separately sold ReefRun Dual DC Pump Controller.
ReefRun G2 4000 Features
- Adjustable DC return flow: Provides 2000-4000 LPH / 530-1060 GPH for dialing in sump turnover and plumbing performance.
- Silent sine-wave motor: Red Sea's advanced DC motor design is built for very quiet operation even at higher output levels.
- Independent flow controller: The included flow controller allows manual on/off control and flow adjustment without an internet connection.
- ReefBeat-ready smart operation: Add a ReefRun Dual DC Pump Controller to unlock app scheduling, quick actions, alerts and linked pump control.
- Safety shutdown protection: Built-in protection shuts the pump down if dry-running or a stalled impeller condition is detected.
- Flexible outlet positioning: The rotatable outlet helps adapt the pump to different sump and plumbing layouts.
- Service-friendly construction: Latches provide access to the impeller chamber for easier cleaning and maintenance.
- US and metric plumbing support: Included outlet fittings help adapt the pump to common hard plumbing or flexible tubing setups.

Application and Compatibility Notes
Use the Red Sea ReefRun G2 4000 DC Pump where its flow range and 11.2 ft maximum head height match the plumbing head pressure and desired turnover rate. The pump is supplied for submerged sump installation with outlet fittings, and the inlet can accept standard metric and imperial PVC pipe when installed according to Red Sea's guidance. For smart features, connect the pump to a ReefRun Dual DC Pump Controller.

Setup Directions
Install the pump fully submerged in the sump, attach the four rubber feet, rotate the impeller chamber and outlet to suit the plumbing path, and use the appropriate included outlet fitting for hard pipe or flexible tubing. Keep the flow controller accessible if operating independently, route cables with drip loops, confirm the pump is in water before powering on, and make small flow adjustments while checking the sump level, return line and overflow stability.
