What water pump do I need?
Water pumps come in a variety of models and sizes and can be used for a number of situations. In principle, every type of water can be pumped as long as the appropriate model pump is used. This brings us to the major question: What pump do I need?
Which water pump is most suitable for which situation?
First, you need to be clear about the pump’s intended use, because every water pump has a specific purpose. Every action with the corresponding ranges of pumps is described below:
Draining / pumping dry
Surface drying / puddle pumps
Spraying / irrigating
Filling a pond or a swimming pool
Transferring water
Increasing water pressure
Supplying water to a fountain
Circulating water
Indoor rainwater use

We will be happy to help you find the appropriate model. Please refer to the pump selector (green button at the top of this page). If you specify your wishes and requirements, the selector will work out which pump best fits your situation, and you will be assured that you are choosing the right one.
Draining / pumping dry
Generally, a submersible pump is used if a certain space needs to be drained as a result of flooding or other causes. A submersible pump is immersed in the water source, using a discharge hose to drain the water to the required location. This pump is capable of processing clean water as well as dirty water that contains solid particles. However, the most important aspect of a water pump is the size of the solid particles it allows to pass through. A submersible pump can be used for draining flooded cellars, wells, rain barrels, manure pits, and much more.
Surface drying / puddle pumps
If the area needs to be drained practically 'mop dry', a puddle pump is your best option. These pumps drain a surface dry to about 0-2 mm, and are therefore only suitable for processing clean water or rainwater.
Spraying / irrigating
You can opt for a garden pump to irrigate your garden, greenhouse, or allotment. These come in different models, and the main difference is their delivery head, suction depth, and pump capacity. The deeper the pump needs to draw water from, the more water pressure will be lost. Every pump we supply has a chart that indicates what water pressure can be supplied at which depth.
Filling a pond or a swimming pool
When filling a pond or a swimming pool, you need a water pump that is able to process clean water and transfer water under high pressure. Generally, a garden pump is used in this situation.
Transferring water
If you need to transfer clean or dirty water, you need a self-priming pump, which is fitted with both a suction hose and a discharge hose. The suction hose is placed with the self-priming pump in the water source so that the water is transferred through it into the pump. The water is then drained through the discharge hose. Usually, a garden pump is used in this situation.
Increasing water pressure
Booster pumps, also known as water-pressure increasing pumps, are mainly used in houses where the water-pipe pressure is considered to be too low. They are ideal in old houses with old water pipes and maisonettes or apartments, but also for use in houses with an extra shower, toilet, tap, or washing machine.
Circulating water in a swimming pool
Pond water needs to be circulated so that no substances can develop that may harm its habitat. Water circulation also contributes to a better absorption of oxygen and carbon dioxide, which keeps the water healthy. The same applies to swimming pools, which need circulating water to ensure that the water in which people swim remains healthy.
Indoor rainwater use
You will need a rainwater pump if you want to use rainwater within the house. These pumps ensure that rainwater, as well as clean water, can be reused: for example, to flush the toilet, during which 13,000 litres of water are used per person per year. With a rainwater pump, this amount of water could partly be reduced by reusing rainwater, or wastewater from a washbasin or shower.
