Calculate pond pump - that's how it works
The correct dimensioning of pond filter and pond pump is one of the most difficult tasks in pond planning. How to correctly calculate the necessary pumping capacity of the pond pump, and which factors must be taken into account, can be found in our article.
Dimension pond pump and pond filter
In our special article we have already talked about the correct dimensioning of the pond filter. It is much more dependent on the amount of contaminants entered than on the actual pond volume. So the type of pond is especially important, and less the size.
Again, other criteria apply to sizing the pump - some of the factors that already mattered to the filter (such as the type and quantity of fish stock and the amount of food that is introduced) also play a role here.
circulation cycle
The most important criterion when calculating the pump is the circulation cycle.
This means nothing more than the frequency with which all the water in the pond is sent from the pump through the filter. Next to it is also the Delivery height of the pump an important criterion for selection. It is reduced by long lines and directly influenced by the cross-section of the lines.
The correct circulation cycle can only be determined by several factors:
benchmarks
For fish ponds, the circulation rates are relatively high, which means that even high pumping capacities are required.
Usually one assumes at least one revolution within three hours. In some cases, much higher circulation rates can be recommended - up to half-hourly changes. Even higher are circulation rates only in aquariums.
For swimming ponds, the circulation rates can be significantly lower - once in three hours is the maximum, but in most cases, the realistic value will be significantly lower.
Garden ponds need no upheaval at all, and in many cases this is rather counterproductive because it overrides the self-cleaning of the pond.
calculation
Based on the circulation rate, you can easily calculate the pump capacity:
With a circulation in two hours and a pond volume of 10,000 liters, the pump can easily afford 5,000 liters / h.
Tips
Be sure to get detailed advice on fish ponds if you are not familiar with them. Without a specialist errors will inevitably happen here and can hardly be avoided.
