Water Pumps

Water pumps come in all shapes and sizes. The technologies used to pump water are varied and have been developed to satisfy specific issues relating to flow, pressure, driver and purpose or duty. For the simple water pump to irrigate a garden from a rain water tank to a more sophisticated submersible water pump to drive a sprinkler or a decorative fountain in a water feature. In this section we concentrate on the water pump which is specifically designed for water pressure systems, water transfer from one tank to another or from a  river, stream or dam to a storage tank or reservoir.

Here we concentrate on the two major ranges in our product portfolio, products we stock and are able to ship to users either on the same day or within 24 hours.

Ebara water pumpsThere are a number of factors one needs to consider when selecting a water pump for domestic use.

Firstly, where will the pump draw water from? A tank above the ground, a tank or sump below the ground, a river, stream, dam? This section of our site is predominantly for a duty where the pump will draw from a tank above the ground. For below the ground sumps please click on our tag for self priming pumps, and for submersible pumps on that tag.

Secondly, what is the highest point or what pressure does the duty call for? If you are considering pumping from a storage tank above the ground to a house, the operating pressure of the geyser as well as the highest point of the delivery pipe will need to be considered.

Thirdly, what volume in litres per minute will be required?  When one considers a normal household tap requires between 9 and 14 litre per minute at 2.5 to 4 bar, the best way to determine the flowrate required is to estimate how many taps could run at any one time.

For example a bath is being drawn (2 taps = 18 litre per min) a toilet is flushed (1 tap = 9 litre per min) a washing machine is running (1 tap = 9 litre per minute) and a hand basin is being used to wash hands (2 X 9l/min =18 l/min) total possible taps at any one time is now 54 litre per minute.

Fourth, what power is available to drive the motor, 220 volt single phase or 380 volt three phase?

Once you know this information the next step is to select the correct pump based on the flow rate or volume in litres per minute and the head at that flow rate.
