Pump Types

With all the different types of pumps available on the market today it can be a confusing and frustrating task to select the right pump for your water feature or pond. We will take a look at the 2 main types of pumps available and what you will need to look for when selecting a pump.

 

Submersible pumps

These are most commonly used in water features and smaller ponds. The pump is completely submerged in the water. The suction of the pump is usually positioned on the side or bottom of the pump. The water is then sucked through the pump and out through the outlet through a pipe or nozzle circulating the water. The smallest submersible pumps available will pump a flow rate of +/- 200 litres per hour and a height of 25cm while the larger pumps will deliver 25000 litres an hour and pump a height of 10 meters. Submersible pumps are the most economical pumps to run.

It is South African law that all submersible pumps used outdoors are fitted with an earthed 3-core 10-meter cable.  A submersible pumps suction area needs to be cleaned regularly to avoid the impeller becoming blocked, causing the pump to burn out.

                       

External pumps     

The most common external pump used on water features is the swimming pool pump. These are ideal for larger water features and ponds that require a high flow rate of water. There are various sizes of pool pumps available with smallest delivering 5000 litres per hour and the larger pumps delivering up to 40 000 litres per hour.

You will need to draw the water from a point in the feature, usually a bottom drain or weir. The water is sucked through pipe to the pump and then pumped back to the pond or feature. It is important not to install the pump to high above the water level (Max 1.5 meters).

Select the right pump for the job

Selecting the right pump is important.  Most pumps are designed for a specific purpose e.g. pond, waterfall, drainage etc. Check with salesman that the pump is the right pump for your application.

Pump Selection

There are various factors one needs to know before a pump can be selected for a water feature. You will need the following information when selecting a pump for a water feature or pond:

• The head of the water feature

This refers to the height of the fountain or water feature from the water level that the pump will need to reach. This information will be available on the box of the pump or from the salesman in the shop.

·         The Volume of water required

The volume of water required at the outlet of the fountain. Usually calculated in litres per minute or per hour (m3)

Some water features and fountains will require vary little water to operate while others will require thousands of litres.  This information should be available from the shop you purchase the fountain or on the packaging of fountainheads.

When in doubt, always go for a bigger pump as these pumps can be choked to reduce the flow.

·         The size & length of the pipe.

This is a very important factor. The common belief is that the smaller the pipe the more pressure will be achieved, when in fact it is the complete opposite that is true.

Larger pipe is better as there is less friction loss (the loss of flow and pressure) in larger pipes. You will achieve a far greater flow out of a larger diameter pipe. 12mm pipe is usually ok for small water features that do not require a large flow of water but larger water features & streams will require pipes of 25,40 & 50mm depending on the flow required & distance the water needs to be pumped.

·         The width, length and depth of any streams, waterfalls or over flows.

 

If you are planning a stream or overflow this is very important. The wider and deeper your stream or over flow, the more flow is required. A chart calculating this is attached for you.

Pump Selection (Continued)

From the above example we see that we will require a pump that can deliver 6000 litres per hour at a head of 2.8m We can now use a pump graph to select a pump that will meet these requirements

The graph above shows the performance curve of a range of pumps.

The left axis of the curve shows the litres per minute and the bottom axis shows the head (height)

By drawing a line from the head we require we can see that an h12000 pump will deliver the flow and head that we require to operate the water feature.
