Strong water movement is the heart of a healthy aquarium—improving oxygen exchange, carrying nutrients, pushing debris into filters, and ensuring stable conditions for fish, plants, and corals. Whether you have a sleek planted tank, a powerful sump system, a marine setup, or a high-flow aquascape, you need a pump that delivers reliable performance without taking up much space. This is exactly what the EHEIM compactON series is designed for: compact size paired with remarkable power.
EHEIM compactON pumps live up to their name by offering a small footprint while delivering flow rates ranging from 170 litres per hour to an incredible 16,000 litres per hour. With nine different models available, you can choose the perfect pump for everything from nano aquariums to large sumps or marine reef systems.
Most models allow you to fine-tune the flow rate—an essential feature for customizing circulation in:
Planted aquariums
Shrimp tanks
Sump filtration systems
Marine tanks
Breeder setups
Display aquariums
Models 5000/9000/12000/16000 come with fixed flow outputs due to their high-capacity performance.
The larger compactON models (2100–5000) can be converted for outside-the-water use, making them ideal for:
Sump return pumps
External circulation setups
Advanced filtration systems
Marine protein skimmer feeds
This flexibility means the pump grows with your needs and works across different aquarium setups.
Marine setups require corrosion-resistant materials, and EHEIM delivers exactly that. The pumps are made using premium materials that withstand saltwater conditions without compromising durability or safety.
Compared to the older EHEIM compact and compact+ series, the compactON pumps offer:
Much better power efficiency
Reduced energy consumption
Improved flow dynamics
Higher delivery head
Longer service life
This makes them perfect for long-term use in both hobby and professional tank systems.
One of the biggest concerns in aquarium setups—especially those placed in bedrooms or living rooms—is noise. EHEIM addresses this using:
Ceramic bearings and axes (in models 2100/3000/5000/9000/12000/16000)
Vibration-reducing design
Stable mounting with robust suction cups
The result? Smooth, silent, uninterrupted performance.
Every compactON pump includes:
Robust suction cups for secure mounting
Suction basket to prevent debris entry
Threaded coupling for easy hose connections
Accessories for internal & external configuration (in larger models)
These features make installation simple, reliable, and maintenance-friendly.
EHEIM ensures top-tier safety through:
Thick cable insulation
Non-toxic materials
Heat-resistant components
High-grade plastics suitable for long-term immersion
This protects both the aquarist and the aquarium inhabitants.
Because of its versatility and quiet operation, compactON is perfect for:
Planted aquariums
Sump systems
Tropical freshwater tanks
Goldfish tanks
Marine reef setups
Terrariums & paludariums
Indoor aquaponics
