Environmental
A clean environment requires reliable technology – even underwater.

Environmental technology places particular demands on drive components: systems for water treatment, wastewater treatment or aeration often operate continuously, are difficult to access and must function reliably under adverse conditions – wet, corrosive, deep below the water’s surface. Maintenance-free operation is not a matter of convenience, but a technical necessity.

CHEMNITZER ZAHNRADFABRIK develops specialised gearboxes for environmental technology applications that meet precisely these requirements – even where other manufacturers reach their limits: underwater.

Typical requirements for the gearbox

• Continuous operation in damp, wet or fully submerged conditions
• Absolute watertightness and resistance to corrosive media
• High efficiency for energy-efficient continuous applications
• Low-maintenance or maintenance-free designs for hard-to-access locations
• Resistance to dirt, deposits and biological influences

What we offer

We develop underwater gearboxes and specialised gearboxes for environmental technology, with a particular focus on watertightness, material resistance and durability. Our experience with underwater applications at depths of up to 15 metres is demonstrated by the projects we have completed – including oil-sealing chambers and leakage monitoring systems.

Typical gearbox types and application examples

• Single-stage and two-stage submersible planetary gearboxes with high efficiency for depths of up to 15 m
• Submersible helical gearboxes with oil seal chambers and leakage monitoring, available in various power ratings and gear ratios
• Gearboxes for submersible aerators with power ratings up to 90 kW
• Drives for sewage sludge agitators and aeration systems
