Aquabee Pump


Aquabee is a German manufacturer of pumps and filter technology for aquaristics, founded in 1977. Aquabee is one of the oldest and longest lasting pump companies in the aquarium hobby, they also were one of the first company to build a needle wheel pump for the patent holder Deltec. With decades of experience, Aquabee can offer the highest-level quality of pumps for demanding saltwater aquariums. They have been used very successfully for many years all over the world.


The Aquabee UP series pumps is with simple and robust construction. They offer an extremely long service life. Due to the extraordinarily good performance of this pump series in terms of flow rate, water column (water-air intake) and energy consumption, it can be used in a variety of ways, for example as return pumps or as flow pumps. They are ideal for the skimmers. 

The pump is made from selected materials. The shaft and plain bearing bushes are made of the toughest durable ceramic. The aging-resistant and vibration-damping silicone bushings, in which the plain bearing bushes are enclosed, ensure very smooth and quiet running. Aquabee manufactures the needle wheel from POM (Polyoxymethylene), also known as acetal, polyacetal and polyformaldehyde. The plastic POM has a much higher strength compared to other plastics. This makes the needle wheel extremely resistant.


Aquabee and OneCove have established deep cooperation relationship since 2010.  Onecove skimmers and calcium reactors are completely designed around the Aquabee line of needle wheel pumps. The high-performance pumps provide an important guarantee for our products.
