The SunSun CW-160 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 saving 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 marine aquariums, as corals and some fish cannot do without natural currents. 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 floor. The control of this wavemaker pump features a light sensor that allows for automatic switching between day and night modes when light conditions change. The daylight sensor ensures a natural reduction of the waves as darkness falls.

The SunSun CW-160 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 1,700 to 20,000 liters per hour while consuming only 60 watts. The low-wear ceramic shaft guarantees a long lifespan for the aquarium pump. The rotors of the aquarium circulation pump are modeled after the design of a ship's propeller, producing a smooth and wide flow with minimal power consumption.

All electronic components are encapsulated in epoxy resin, providing optimal protection. The SunSun CW-160 circulation pump with controller is suitable for aquariums measuring 150 to 200 cm in size.
