Finding the right garden pump – that’s what it’s all about

Garden pumps can often be found in households that have a garden with a pond, fountain or rain barrel. There are different types of garden pumps that optimally master the requirements for each other task. There are also differences in the quality and accessories of the individual garden pumps. So what should be considered when buying a water pump for the garden?

For an optimal garden irrigation you need a suitable pump.

Fields of application of the garden pump

There is a lot of work to do with your own garden. Especially in the hot summer months can not be expected with sufficient rain for all plants and other irrigation methods must be used.

With the garden pump, the whole garden can be supplied with water. Some garden pumps also manage to dry ponds or flooded cellars. Likewise, this aid is often used to clean the patio or balcony. The domestic waterworks supplies the house and the garden quickly and with water as needed.

How does a garden pump work?

With a water pump, water can be transported from one place to another. It can be poured with plants and it can be aspirated water. The latter is often done in floods to keep the plants from drowning.

Water pumps are powered by electricity. The pump is simply connected to the power line of the house. Incidentally, the water pump is also referred to as a flow pump. Inside is namely an impeller, which is driven by nozzles and finally creates a strong negative pressure. This creates a strong flow and a suction force, with which it is possible to absorb water.

Purchase criteria for a water pump

A garden pump for private use in the garden, for example, does not have to be expensive. There are good garden pumps already for under 100 EUR. For large irrigation or drainage projects, the price of a suitable water pump can already be 300 EUR.

Whatever matters is the performance. But this is not true, more is more. Higher performance is usually accompanied by a longer conveyor length. The power does not have to be as big for a low well as it is for a deeper one, which eventually causes the pump to be larger. The correct head, also known as the conveyor length, can be opened up when it is clear how far the distances between the water surface and the outlet of the water are.

A delivery height of 40m is usually absolutely sufficient. The suction height of people who want to pump from a well should be at least 9m. To pump out a pool, a garden pump with a suction height of 6 or 7m is sufficient. Likewise, when buying it should be noted that the flow rate is large enough. The largest flow rate is found in devices with high performance.

An output of about 4000 liters is the benchmark for a pool. If you want to irrigate your garden with rainwater from a ton, you can also use a water pump with a flow rate of about 3500 liters.

Overload protection is now integrated in almost all garden pumps. If the device overheats, it will shut itself off, so it will not break. Another purchase criterion is the accessories. In most garden pumps the necessary small parts such as connection adapter and attachment for the hose are included in the package of the product.

Types of garden pumps

Most garden pumps are actually talking about irrigation pumps. The flow rate of an irrigation pump is about 2000 to 4000 liters and the head is usually set to 9m. This garden pump can be easily used for the Sprenkelanlage.

The perfect helper to water a large garden.

Another type of garden pump is the submersible pump. This is often used to vacuum the water in a flooded basement. In contrast to the other garden pumps, this works with very little pressure, which is why the water pump is not suitable for the lawn sprinkler and also has no high head.

Apart from the dipping and irrigation pumps, some houses have their own domestic waterworks, which should ensure the adequate supply of water, regardless of the urban water supply.

The domestic waterworks are mainly found in houses in whose garden there is a well. It has, unlike the other water pumps, an electronic pressure switch. For pumping out large water points, such as ponds, for example, dirty water pumps are often used.

A normal garden pump became clogged after a short time due to stones and other larger dirt. This is not the case with the dirty water pump , because this is far less prone to it. Who wants to buy a dirty water pump, must pay attention to the maximum grain size. This allows greater contamination of the water when it is itself large.

Garden pumps manufacturer

It is worthwhile to buy models of well-known manufacturers when buying a new garden pump. Renowned garden pump manufacturers include Gardena, Einhell, EDE, Makita, Metabo and Homa.

Why are garden pumps with pressure switches available?

Not all garden pumps have a pressure switch. It is above all domestic waterworks that are equipped with a pressure switch and can react quickly to “changing pressure”.

In addition, a pressure switch can be mounted on many garden pumps. The pressure switch responds to increasing and decreasing pressure by switching the garden pump off and on. In this way, the water is transported evenly.

The desired water pressure can be adjusted before using the garden pump. Pressure switches are relatively expensive, so before purchasing a particular model, you should be aware of some criteria, such as turn-on and turn-off time, material, dry-running protection, and operating pressure.

Garden pump and domestic waterworks – What is the difference?

A domestic waterworks is used, for example, when using the washing machine when operating the toilet flush. In contrast to a garden pump, the house water system switches on or off by itself, depending on how high the water pressure is. The domestic waterworks therefore has its own pressure control, through which the water can be provided within a very short time, without having to pump for a long time.

Another difference between these two types of water pumps is mobility. A garden pump can be easily transported, while the house water plant is a permanently installed water supply system, so can not be transported.

How strong must the pump be?

How strong the pump must be depends on the depth of the water surface. If it is a well from which water is to be pumped out, a high suction height and adequate power is required. Most garden pumps have a suction height of about 8 meters and a power of about 3000 watts.

What does the suction height mean?

The suction height describes the distance between the pump and the water surface. Usually good garden pumps have a suction height of eight or nine meters. The suction height plays an important role especially when buying a new garden pump, if wells or low-lying water points are to be pumped out.

How to connect a garden pump?

A suitable suction hose with coupling is connected to the garden pump. It is advisable to use a hose with a check valve or to buy a check valve if this is not included in the scope of the garden pump set. The garden pump itself must be connected to a suitable power source.
