A pond water pump can serve many purposes whether purely for aesthetics or for a specific function. Some transfer water to feed other ponds, streams, waterfalls and fountains. Some help to aerate the pond water while others recirculate the water through filters or water treatments.

Choosing the best pond water pump.

Quality is important, as is the serviceability and lifespan of your pump. Don't make the mistake and assume that if you have two pumps with the same power output, that they will have the same water output.

For example, a pump made in China may say that it has a power output of 120watts and pumps 1000 litres per hour. If this pump breaks down, there may be no option but to replace it with a new one. A more expensive pump made in Germany (with a five year warranty) may also pump 1000 litres per hour but only need half the power to do the same job. The savings in purchasing the cheaper pump, will end up costing you in the long run through higher operating costs and serviceable life.

Pond water pump sizing is important, as oversized equipment can cost much more, through excessive power consumption.

As a guide we recommend that for a natural looking water fall you need to allow 2000 litres of water per hour for every 10cm in waterfall width. Therefore if you want a waterfall 50cm wide then you need a pump that produces 10000 litres of water per hour.

Fountains and water jets have specific needs to get the correct look. You need to look at the height that you wish the jets to push up to and then the flow rate required for the outlet. These specifications are found on manufacturers reference charts.

Pond aeration helps to improve the water health for most pond life.
