Tunze Turbelle® 6105 ORCA black

TUNZE® ORCA MK2 is a high-quality oscillating unit for circulation pumps, developed through a collaboration between TUNZE® and the German start-up ReefHub. What began as an innovative idea is now being brought into series production: with sophisticated technology, high-quality materials, and our decades of experience in marine aquariums.
TUNZE® ORCA MK2 allows the circulation pump to be moved dynamically in the aquarium: precise and software-controlled by the extremely user-friendly TUNZE® app. This allows changing flow conditions to be created that mimic the natural movement of the sea. In combination with the TUNZE® App, not only the direction but also the flow strength can be precisely controlled depending on the angle of rotation. The result: less pumping, more movement, and maximum control over the flow.
Turbelle® stream 6105 ORCA is a complete set: pre-assembled, integrated, reliable. And, of course, with a 5-year warranty.

Specifications

Orientation and flow –

perfectly matched

The TUNZE® ORCA oscillating unit not only controls the pump's rotational movement, but also allows the flow rate to be adjusted depending on the angle of rotation. For targeted flow scenarios – powerful or gentle, depending on the orientation.

Complete system:

Oscillating unit + pump = plug & play

All from a single source: The TUNZE® ORCA oscillating unit is delivered as a fully coordinated system – including pump, mount, and app connection. Unpack, assemble, and start.

Made in Germany –

real manufacturing expertise

TUNZE® ORCA is built where we bring plastics, electronics, PU encapsulation, and system assembly together every day: in our production facility in southern Bavaria. From the electronics to the cables – many key components come directly from Germany or are manufactured in-house.

5-year warranty –

built for true long-term use

Designed for many years of operation in marine environments – including high-quality German-made drag chain cables. The warranty also applies to wear parts.

Magnetic encoder

for precise position detection

An integrated magnetic sensor precisely measures the pump's alignment. This ensures reliable alignment – without offset, without jumps, and without deviation.

Waterproof & corrosion-resistant

The electronics and control system are fully encapsulated in PU resin. All seals are securely designed. The TUNZE® ORCA oscillating unit is protected against splashes of water and temporary submersion.

Versatile mount

for glass thicknesses up to 22 mm (0.87")

The included mount is suitable for both pools and aquariums with glass ledges. Installation is tool-free, secure, and flexible.

Finely adjustable length

The carbon tube can be adjusted in fine increments without the need for tools. The high-quality carbon fiber construction allows for flexible height adjustment with high stability. 

Control via TUNZE® app

The native, intuitive TUNZE® App (iOS & Android) controls all parameters. It serves as the central all-in-one platform for the entire TUNZE® system – developed by aquarists for aquarists.

Certified medical device power supply –

maximum safety

Medical device-certified power supply with high operational reliability, power reserves, and high efficiency. A strong heart for your TUNZE® ORCA.

Turbelle® stream 2 eco

The Turbelle® stream 2 pump — often seen as a role model for other stream pumps on the market— is still a standard in reef aquaristics, which has been continuously developed over the last 15 years. Today, new technologies such as numerical fluid mechanics are available for optimization.

By using these and with the ambitious goal of developing the most efficient controllable stream pump in the world, we have now succeeded in achieving a volume flow of 12,000 l/h (3,170 USgal.) with only 11 W of power consumption of the new Turbelle® stream 6105 eco. For the first time, we have achieved an efficiency of over 1,000 l/h/W (264 USgal./h/W ), which was long considered unattainable. With 365 days per year, this means 175.2 kWh per year. At 0,35 €/kWh / 0.30 £/kWh / 0.30 $/kWh there is a saving of approx. € 306,6 / £ 263 / $ 263 within the warranty period.

By that, the Turbelle® stream 2 has more than earned the designation "eco"!

High efficiency >1000 L/h/W

12,000 l/h volume flow rate with only 11 W power consumption for an efficiency of over 1,000 l/h/W.

High-tech cable especially for demanding aquaristics

With remarkably high abrasion resistance, seawater resistance and extreme resistance to mechanical impact. As a result, it does not harden in water like PVC cables. With an extra high-contrast intermediate cable sheathing to detect damage at an early stage.

Produced in Bavaria by MEDI Kabel.
