The SunSun CW-120 circulation pump is one of the most efficient pumps in the aquarium hobby.

When comparing the power consumption of the CW series with other aquarium pumps, it becomes clear that the trend towards energy savings has been correctly recognized and implemented. Aquarium pumps are designed for continuous operation, and every watt saved is a relief for any budget.

Circulation pumps play an important role in aquaristics, especially in saltwater aquariums, as corals and some fish cannot do without a natural current. The purpose of circulation pumps is to simulate this natural flow in the aquarium. Often, circulation pumps are installed in opposing directions to create a diffuse current. The currents generated by the aquarium pump limit the settling of unwanted sediments on the aquarium's substrate. The control of this wavemaker pump features a light sensor that allows for automatic switching between day and night modes as light conditions change. The daylight sensor ensures a natural reduction of the waves as darkness falls.

The SunSun CW-120 wavemaker circulation pump can be swiveled 45° in any direction when mounted on its bracket. The outlet nozzle of the circulation pump also allows for a 45° swivel in any direction. The pump performance ranges from 700 to 8000 liters per hour, with a power consumption of only 20 watts. The low-wear ceramic shaft ensures a long lifespan for the aquarium pump. The rotors of the aquarium circulation pump are designed based on the construction of a ship's propeller, which produces a smooth and wide current with minimal power consumption.

All electronic components are encapsulated in epoxy resin, providing optimal protection. The SunSun CW-120 circulation pump with controller is suitable for aquariums measuring 70 to 120 cm.
