CHJ-2000/2500

The SunSun CHJ-5000 Pond Pump with 5000 l/h with 80 Watt is one of the pumps with the highest efficiency – Output per Watt.
Comparing the power consumption of the CHJ Pond-Pump Series with other pond pumps, you will notice that the trend to save energy was correctly identified and implemented. Pond Pumps are always in continuous operation, every Watt savings is a relief for every budget.
Pond- and Aquariumpumps are always in continuous operation.

Filterpump / Aquariumpump / Streaming Pump:
Convince yourself of the advantages of these pumps, depending on the power output per liter, the pumps are particularly suitable for ponds or aquariums.
In order to prevent an overflow of the pond filter in conjunction with these strong pumps, we recommend using a Y-Adapter. Used as a By pass, an additonal stream can be supplied. You also could use the by pass to operate another clarifier or filter.
SunSun has installed a Inflow Adjustment in the construction of the pump:
Adjust the flow to the pump- infinitely

Additional Strenghts of the CHJ Pond-Pump Series are the especially quiet engines and the suitability for Fresh- and Sea Water.

The capacity of the pond pump must be necessarily adjusted to the size of the pond filter. Any oversized flow rate will result in an overflow of the pond filter which is to be prevented at all costs. Moreover, you should take into account the pond´s circulation cycle as well as the period of time of the pond water in the pond filter.
According to the type of usage, the ideal circulation cycle depends on different factors: the fish population, aquatic plants, the quantity of sunlight or the desired water clarity. It goes without saying that, as the case may be, there are further components of the filter circuit that are to be coordinated, if necessary.

The following information may serve you as a guideline:
Koi pond / Fish pond:
• 1 cycle per 3 hours
• 2 circulations in 1 hour (without plantings and with large fish population)

Garden pond / Plant pond:
Regarding a pond without fish, there is less circulation necessary. One circulation in a day can be taken as a guideline in order to enrich the pond water with oxygen and to keep the water in constant movement.

Swim pond:
In this case the circulation cycle is highly dependent on the planting and the individual claim.
The upper limit is to be made at 1 x in 2-3 hours, the lower limit at “no circulation”.

Cleaning of the pond pumps:
In order to ensure a proper function of the pond pumps it is indispensable to clean them regularly.
SunSun has created the housing so that you don’t need any tools to open it (no screws).
With just one handgrip, you can pull the pump out of it.
