This brewing or circulation pump from our brand SunSun is ideal for freshwater and saltwater aquariums. The capacity of the pump is 2000 liters per hour with a power consumption of only 2.5 W. Circulation pumps play a particularly important role in seawater aquariums in the field of aquariums, since corals and some species of fish absolutely need natural circulation. Thanks to these pump-generated mixes, unwanted sediments are virtually no longer placed at the bottom of the aquarium. The pump rotor, designed at the base of a propeller, imparts wide and even circulation to water. In addition, our Wavemaker device can be rotated 45° in each direction. The brewing pump is attached using suction cups or a magnetic holder sold separately (item number 50239). Corrosion-resistant carbon steel shaft ensures a long service life of the pump. All electronic parts are encapsulated in polyepoxide for optimal protection.
