Water Pump

Which pump do I need for my project? Choosing the right garden pump

There are several types of pumps, each with their own specific uses. Which pump is right for you depends on the water source and your needs. We'll explain what types of pumps there are and what you should consider when choosing a pump for your garden irrigation.

Submersible pump vs. domestic waterworks: operating under water or outside the cistern

Submersible pumps are immersed in the water and pump it. They are typically used for wells or cisterns. The great advantage of a submersible pump is that the liquids can be placed under pressure directly, without suction and without air. Therefore, these pumps are very popular in irrigation systems. Depending on the performance of the pump, a submersible pump can also be used in projects where very high pressures are required or the water is to be pumped from great depths. Domestic waterworks have a maximum suction height of about 7 metres. Therefore, in contrast to submersible pumps, these garden pumps tend to be used as water pumps in more shallow conditions. The great advantage of domestic waterworks is that they are always easily accessible in the house or cellar, as the pump is not submerged in the water. These pumps are usually operated with 230V and are self-priming. A waste water pump is intended for other applications.

Products for garden irrigation: properly sizing the pump

To ensure that the pump in your garden has the right fit, the planning of the irrigation system and the sizing of the pump should be done at the same time, if possible. You can begin from two possible angles.

Checking the characteristic curve of the pump to determine the available water quantity

From the characteristic curve of a pump you can fairly quickly determine the amount of water that can be delivered at a certain pressure. For example, the Hunter MP Rotator requires an optimal operating pressure of 2.8 bar. Assuming we have 0.5 bar of friction loss in the pipes and 0.2 bar of friction loss in the valve, then the characteristic curve of the pump must be read at 3.5 bar or 35 m pump height. On the X-axis you will then find the water volume that the pump can deliver at this back pressure.

Determine the total consumption of your garden irrigation - divide into valve circuits and select a suitable pump

An alternative to the approach described above is to search for the right pump on the basis of the required volume or the pressure conditions. One looks for the right pump for the required tasks, so to speak. If, for example, the circuits require a volume of 2 m³/h at 3.5 bar, you can select a pump that offers these specifications.

Pressure pumps are designed to increase the water pressure in your system. These pumps are usually operated with 230 V and can be used for either wells or cisterns.

When choosing a pump for your garden, you should consider the following aspects in context:

• The type of pump you need (submersible, suction or pressure)
• The power source (220V current or high voltage current)
• The flow rate (liters per minute)
• The maximum head (height in meters that the pump can pump the water)
• The warranty (how long the manufacturer will guarantee the product)

Now that you know the basics for choosing the right pump for your garden, it's time to get out there and find a pump that fits!
