How to choose the right pump
This may seem a difficult task as there are so many on the market.
All pond pumps work on the same principle: when submerged the electric motor runs the impeller (the only moving part in a pump). As the impeller turns, water is drawn through the inlet and expelled via the outlet. It's as simple as that!
To get the best performance from your pump you need to choose the correct size for your pond's requirements. It is always better to opt for a larger model than stated in case you want to add more accessories.
WHAT SIZE PUMP DO I NEED?
As a general rule of thumb you should aim to turn over at least half of the full capacity of the ponds volume per hour.
i.e. if your pond is 1000 Litres then you want a pump that produces 500 - to - 1000 Litres Per Hour
WORKING IT OUT:
Roughly calculate the size of your pond using this formula:
Measure in metres, length x width x average depth = volume in cubic metres
Multiply volume by 1000 = Pond size (litres)
Measure in feet/inches, length x width x average depth = volume in cubic feet
Multiply volume x 6.23 = pond size (gallons)
ESTIMATE WATERFALL HEAD HEIGHT:
This is the vertical distance between the surface of the pond and top of the waterfall.
A waterfall requires 1500 litres per hour, flow rate for every 6 inches of width of the waterfall
The pump you choose should be capable of turning over half of the volume of the pond, through the filtration system every hour. e.g. 18000 litre pond, would require a 9000 litre per hour pump.
