The NYOS® VIPER pumps are the ideal feed pumps for your aquarium. They have been adapted especially for the hard conditions in seawater aquariums. Particularly robust components such as durable high performance ceramics made from zirconium dioxide are used. This means that the pumps are almost maintenance-free. The energy-saving yet powerful devices are very quiet in operation and in addition are decoupled as standard by rubber bases. The flow rate of each VIPER pump can be regulated manually and thus adapted to the individual aquarium conditions. NYOS® provides a three-year guarantee on all VIPER pumps. The complete VIPER pump series carries the TÜV SÜD safety seal.
