The Best Pool Pump: Our Choices

Guide: Questions you should ask yourself before buying a pool pump

Who is a pool pump suitable for?

In general, anyone who owns a pool should buy a pool pump. It helps to remove dirt and clean the pool thoroughly. Only if you have a small children's pool where the water can be drained daily, you can do without a pool pump.

A pool pump sucks in the water and then sends it to a filter. The filter catches all the dirt as it passes through and cleans the water. Afterwards, the water flows back into the pool.

In addition, a pool pump has the function of chemically cleaning the water. In doing so, it distributes chemicals in the water that remove other dirt such as sweat or urine in the water.

If this process is not carried out regularly, algae can form in the pool.

To support your pool pump, it is also worthwhile to install a practical pool cover. This prevents coarse dirt such as leaves from getting into the pool in the first place.

Where do I install a pool pump?

The pool pump should always be dry and well ventilated. It is best to install it either in a technical room by the pool or in the garage or cellar. However, the installation must not be too far away from the pool.

The filter system can be placed either 3 metres above or below the water level. It is also important that the surrounding temperature does not exceed 40°.

If the pump is to be installed above the water surface, however, you must buy a self-priming pump and make sure that there are non-return valves in the hoses.

In addition, drainage should be possible in the technical room so that the pump does not get wet and get damaged.

Which sand should I use for a pool pump?

If you have decided to buy a sand filter system, you will certainly want to know which sand is best to use. It is generally recommended to use quartz sand.

In addition, it should comply with DIN 12904 for drinking water treatment, which ensures that the sand does not contain any harmful substances. However, this is not specified for all products.

In addition, there are also different grain sizes that you need to consider. Basically, the finer the sand, the better the filtering result. However, if the sand is too fine, it may be backwashed.

Of course, you should always follow the manufacturer's instructions, as some systems are not suitable for finer sand.

Optimal filtration is achieved by using several layers of grit. Three layers are recommended as the most effective. From the bottom to the top, the sand should become finer and finer.

In the following table we show you the recommended grain sizes for each layer.

Layer
1st layer 3 - 4mm
2nd layer 2 - 3mm
3rd layer 0.4 - 2mm

What does a pool pump cost?

The price of a pool pump can vary greatly. Most pool pumps range in price from €30 to €350.

However, you can sometimes spend over €1000 for a high-quality and powerful pool pump.

The performance of a pool pump is the most important factor for the price. The materials also play a role. Some materials wear out more slowly, which is why you usually have to pay more for them.

The type of pump is also important when it comes to the price. Generally, self-priming pool pumps or pool pumps suitable for sand filters cost a little more.

Type price range
Cartridge filter system 30 € - 150 €
Sand filter system 65 € - 350 €
Self-priming pool pump 80 € - 300 €

What are the alternatives to pool pumps?

If you own a pool, unfortunately you can't get around a pool pump. It is important because it cleans the pool of dirt.

However, there are filter balls for sand filter systems that you can use instead of sand. These last longer and are therefore definitely cheaper.

As an alternative to a pool pump, a practical pool robot can also help keep your pool clean.

Decision: What types of pool pumps are there and which is the right one for you?

In general, you can distinguish between three different types of pool pumps:

  • Sand filter system
  • Cartridge filter system
  • Self-priming pool pump

These different variants have individual characteristics that come with specific advantages and disadvantages.

Different types of pool pumps are better suited for different circumstances. In the following section, we want to help you find the right version for you.

For this purpose, we will present the types just mentioned in more detail and explain their respective advantages and disadvantages.

What distinguishes a sand filter system and what are its advantages and disadvantages?

In a sand filter system, the water is passed through sand and thus purified. Quartz sand is often used for this purpose.

Sand filter systems have a high cleaning capacity and are therefore particularly suitable for larger pools. However, this is also reflected in the price, as they are somewhat more expensive to purchase.

The sand in such a filter system should be cleaned once a week. To do this, the water only has to be directed in the opposite direction. In addition, most systems have a pressure gauge that indicates the degree of contamination, so you can easily see when the filter needs to be cleaned.

Advantages
  • Easy sand change
  • Suitable for all sizes
  • High performance
Disadvantages
  • Higher purchase price
  • Regular sand change is necessary

What are the characteristics of a cartridge filter system and what are its advantages and disadvantages?

In a cartridge filter system, the water is cleaned with the help of paper filters. This is also passed through the filters, where the dirt gets stuck.

As these filter systems have a lower capacity, they are particularly suitable for smaller garden pools. This also makes them significantly cheaper.

However, the filter cartridges must be replaced more frequently than with sand filter systems.

Advantages
  • Convenient cleaning
  • Convenient handling
  • Less expensive
Disadvantages
  • Lower performance
  • Frequent filter replacement is necessary

What distinguishes a self-priming pool pump and what are its advantages and disadvantages?

Self-priming pool pumps are powerful and can circulate large amounts of water, making them ideal for larger pools. In addition, the water is cleaned regularly with the help of the automatic system.

Depending on the size, the water is sucked out either with a skimmer or an overflow. Due to the high circulation capacity, chemical cleaning agents can be distributed very well in the water and help to clean the pool.

This pump has the option of connecting a pool vacuum cleaner, which is often compatible with a pool heater.

Advantages
  • Regular, automatic filtration
  • Suitable for large amounts of water
  • Compatible with pool heater
Disadvantages
  • High purchase price
  • Greater power consumption

Buying criteria: You can use these factors to compare and evaluate pool pumps

In the following, we will show you which criteria you should consider and help you decide between the various pool pumps.

The factors you can use to compare pool pumps include:

  • Power output
  • Flow rate
  • Delivery head
  • Diameter connections
  • IPX4 water protection
  • Max. Water temperature

In the following sections, we explain in more detail what the individual criteria are.

Power output

Among other things, the power output determines the general performance of a pool pump. In principle, the higher the power consumption, the higher the performance should be. However, this is not always the case.

With a high output or a large pool, a pool pump can significantly increase electricity costs. However, the power output should not be too low either, because then the cleaning agents are not distributed properly in the water.

A good pool pump should be able to completely circulate the water in the pool in 6 hours.

In addition, the best pool pumps have a good balance between their power consumption and their circulation capacity.

Flow rate

The flow rate of a pool pump indicates how much water it can circulate within one hour. The higher the output, the shorter the pump has to run and the pool can be used more often.

A pool pump should have a capacity of at least 10 cubic metres, i.e. 10,000 litres, per hour. For larger pools, 15 - 20 cubic metres per hour are recommended.

When choosing a pool pump, you should therefore be guided by the capacity of your pool in order to find the right performance.

Head

The delivery head also gives an indication of how high the output of a pool pump is. It describes the height to which the water can be pumped after cleaning.

With the help of the delivery head, you can control how much water you want to fill into the pool after cleaning. (Image source: 123rf.com / 52684760 )

The greater the difference in height and the distance, the lower the pump's output. The speed at which the water can be circulated therefore decreases.

When buying, you should note that manufacturers usually base their specifications on operation with a small difference in height. Sometimes, however, a performance diagram is included, which indicates how strong the pump performance is at which height.

Diameter of connections

The diameter of the connections also plays a major role in the selection of a pool pump. If they do not match, you will not be able to connect the pump at all.

To do this, you need to look at the connections of your pool and the filter tank. Many pumps have two different sizes of hose connection.

IPX4 water protection

This water protection indicates the protection class of a pool filter system. More precisely, it describes how high the protection against water is for electrical devices.

The IPX4 classification means that there is protection against splashing water. If the pump has a protection class of IPX5, this means that the pump is protected against jet water.

Nevertheless, we recommend installing the pool pump under a roof to avoid the risk of a short circuit in the event of rain.

Max. Water temperature

Since some pool pumps react sensitively to hot water, the manufacturers often specify a maximum water temperature. If this is exceeded, the unit can suffer damage.

However, water in Germany does not usually exceed 35°C. If you either own a whirlpool or would like to buy one, you must of course place more value on the highest possible water temperature.

To keep your pool pleasantly warm at all times, it is worth buying a solar-powered pool heater.

Facts worth knowing about the pool pump

How long should I run a pool pump?

There is no concrete answer to this question. The running time depends on the size of the pool and the power of the pump.

It is sometimes recommended to run the pool pump up to 8 hours a day. However, the running time should be well observed, as otherwise the electricity costs are unnecessarily increased.

In general, it is recommended to run the entire water through the filter system twice a day. For orientation, you can then take the capacity by the circulation rate.

For a pool size of 20 cubic metres, 40 cubic metres would have to be circulated. With a pump capacity of 10 cubic metres per hour, you should then run the pump for 4 hours per day.

It is best to divide this between morning and evening. So run it for 2 hours in the morning and 2 hours in the evening.

How often do I have to backwash a pool pump?

You can tell when it is time to clean the pool pump by the decreasing pump performance. Basically, you should backwash the pump at least once a week.

The process does not take too long (5 to 20 minutes).

If the pump is used a lot in summer, it is recommended to clean it 2-3 times a week. You can also see more precisely on the pressure gauge when the pressure is dropping and the pump should be cleaned.

You should also change the sand in the filter system every 2-3 years.

Do I have to switch off a pool pump during a thunderstorm?

In general, as with all electrical appliances, it is better to unplug the pump during a thunderstorm to prevent overvoltage. However, if the pump has sufficient water protection, you can leave it running.

It must have at least IPX4 protection. However, it is better to have IPX5 protection. In addition, you can also buy a tarpaulin or box that protects the pump even better from the water.

The power cable must also be made of rubber. Otherwise it could be damaged by the rain.
