The SunSun CQB-2000 pond pump, with a flow rate of 2300 l/h at 35 watts, is a highly efficient pond pump – delivering flow per watt.

When comparing the power consumption of the CQB pond pump series with other pond pumps, it becomes clear that the trend towards energy savings has been well recognized and effectively implemented. Pond pumps are designed for continuous operation, and every watt saved is a relief for your wallet.

For example: saving 5 watts means 43.8 kWh less per year; you know your electricity price.

Filter pump / pond pump: Let the advantages of these pond pumps convince you. To prevent overflow of the pond filter when using these powerful pond pumps, we recommend using a Y-adapter. When used as a bypass, it can also supply a UVC clarifier or another filter.

SunSun has incorporated an inflow control in the design of the pond pump: you can adjust the inflow to the pond pump infinitely.

The flow rate of the pond pump must be matched to the size of the filter. An excessively high flow rate can lead to filter overflow, which should definitely be avoided. The circulation cycle of the pond and the retention time of the pond water in the filter should also be considered.

Depending on the intended use, the optimal circulation cycle depends on various factors: fish stock, aquatic plants, desired water clarity. Of course, other components of the filtration system may also need to be coordinated.

Cleaning: To ensure the proper functioning of the pond pumps, it is necessary to clean them regularly.
