TUNZE Professional Return Pump – The Silent Heart of Your Reef

Experience the pinnacle of aquarium engineering with the new TUNZE Return Pump. For years, reefers have asked for a return pump that matches the legendary reliability of Tunze’s flow pumps. By integrating the award-winning Stream 3 motor technology, we have created a return pump that is not only powerful but virtually silent and maintenance-free.

The Juwel of Your Sump

Most return pumps are noisy, vibrating boxes that require heavy silicone decoupling. The Tunze Return Pump changes the game. Its advanced magnetic bearing motor eliminates the need for a traditional ceramic shaft, removing the most common point of failure and friction noise.

Key Features:

• Stream 3 Motor Technology: Utilizes Tunze’s flagship motor design, known for its extreme longevity and "magnetic-bearing" system. 

• Whisper-Quiet Operation: The magnetic bearing ensures there are no touching parts in the rotor assembly. You won't even know it's running. 

• Zero-Maintenance Design: No ceramic shafts to break or lime up, and no metal parts in contact with water. It is built to run for years without intervention. 

• High-Efficiency Performance: Capable of pumping up to 6,000 liters per hour (approx. 1,585 GPH), making it ideal for systems up to 500 liters with significant head pressure. 

• Intelligent Controller: Includes an external controller within the Tunze ecosystem, allowing you to fine-tune flow rates to match your overflow perfectly.

• Industrial Build Quality: Features a massive 5-meter (16.4 ft) power cable and a medical-grade power supply for maximum safety and flexibility in installation. 

• Elegant Mounting: Includes a sleek, vibration-dampening stand that beautifully displays the pump while providing an extra layer of stability.

Why Choose the TUNZE Return Pump?

Traditional return pumps rely on ceramic bearings that eventually wear down, rattle, or snap. Tunze’s Magnet-Bearing technology allows the impeller to "float," resulting in a pump that is essentially wear-free. Whether you are building a new premium system or upgrading your current sump, this pump provides the peace of mind that only German-engineered hardware can offer.

Specifications:

• Max Flow Rate: 6,000 L/h (adjustable via controller).

• Max Head Height: Optimized for standard 2-meter reef cabinet heights.

• Power Consumption: Up to 60W at max power (70W PSU included).

• Cable Length: 5 meters.

• Safety: Low-voltage DC, no metal parts in water.
