Specifications

Magnetic bearings – for absolutely quiet operation

The pump of the 9430 is mounted on magnetic bearings. This minimizes friction and prevents humming noises that can occur with conventional bearings.
The result: quiet, smooth operation – day and night, even in noise-sensitive living environments.

Completely axle-free – for uncompromising reliability

The 9430 completely dispenses with traditional drive solutions: no ceramic axle, no metal axle. Thanks to magnetic bearings, a central wear point is eliminated. Furthermore, there are no metal parts in the entire water contact area. This ensures robust, long-lasting, and trouble-free operation.

Adjust once – remains stable long-term

The water level in the skimmer is regulated by a unique, hydraulically tuned leveling system – without manual valves and without moving parts. The adjustment is made once – and remains stable long-term. A clear advantage for aquarists who value reliable, low-maintenance operation.

Proven and long-standing technology – ahead of its time

The DOC Skimmer 9430 is based on a product concept that has been tried and tested over many years and has proven itself reliable in practice – in both private and professional systems. Both the pump and the skimmer design have been continuously developed and specifically modernized to meet today's high standards. Experience and innovation – perfectly combined.

5-year warranty – for long-term operational safety

A protein skimmer performs a vital function in an aquarium – ensuring stable water parameters and protecting sensitive organisms. The DOC Skimmer 9430 is designed to operate reliably for many years – with robust technology, a maintenance-friendly design, and consistently durable components. We back this with a 5-year warranty – an expression of our confidence in the product and its importance to your system.

Made in Germany – developed and manufactured in Penzberg

Developed and manufactured in Penzberg, Bavaria – with extensive experience, our own assembly line, and short distances between development, construction and production. As one of the few manufacturers worldwide, we have our own production facilities for both the skimmer and the pump – a decisive advantage when it comes to quality, control, and perfect coordination. Made in Germany – not just as a label, but as a true level of vertical integration.

Easy to clean – well thought out installation

The pump is firmly fitted on the outside of the housing, allowing the entire skimmer and pump to be removed with a single manipulation. Despite its external location, the pump remains compactly integrated and accessible without tools. No loose tubes, no vibrating attachments – just a robust, enclosed system.

Connected – but not dependent

The 9430 is fully integrated into the digital TUNZE® HUB ecosystem: cloud control, daily profiles, food timer – everything is possible. At the same time, the skimmer can also be operated completely offline – directly by the buttons on the controller. Smart operation – but never mandatory.

Ozone connection as standard – for maximum water purity

The pump nozzle is ozone-resistant and has a dedicated connection for ozone generators. Ozone can be added directly via the air intake – without additional modules or modifications. A true pro feature, integrated and ready for immediate use.
