What to consider when selecting a suitable fountain or pond pump?

Step 1 Determine the pond’s volume (Liters)
- To determine the cubic meter of the pond, measure the length, width and depth of the pond.
- Use the following formula: m (Length) x m (Width) x m (Depth) = m3.
- To work out the liters, multiply the m3 by 1000. 

Step 2 Work out the circulation rate required
- The rule of thumb is that the total volume of the pond needs to circulate every two hours.
- Use the following formula to work this out: Liters x 0.5 = Circulation rate per hour.

Step 3 Measure the pump height required
- The pump height is determined by measuring the height, starting from the ponds surface, to the top/ highest point where the water must be pumped to.

Step 4 Work out which pump size you will need
- Look at the curve diagram provided (an example is on each box).
- Plot the height and draw a horizontal line on the diagram.
- Plot the litres per hour and draw a vertical line.
- Where the two lines meet, the pump to the right side of the intersected lines is the model best suited for your requirements.

Step 5 Check the pump dimensions
- Check to ensure that the pump you select will fit into the pond where it will be installed. The pump needs to be fully submerged at all times, or it will burn out.
