Pool Pump – The Heart of the Pool System

The pool pump can be likened to the heart of the pool system—a component that must operate continuously and reliably to circulate the water and enable filtration. A high-quality, dependable pool pump is therefore invaluable. Although there are many budget options on the market, we have carefully evaluated and excluded several pool pump manufacturers due to recurring quality issues. We have kept only the brands that consistently deliver reliable products to ensure our customers enjoy trouble-free operation and can enjoy their pool without unnecessary interruptions. Investing in a quality pump is a long-term solution that minimizes maintenance and maximizes swimming enjoyment. Whether you are planning to buy a pool or already have one, choosing a robust pump is critical for optimal performance and cleanliness.

What should I consider when choosing a pool pump?

Pool pumps are matched to a specific water flow at a given distance. The rule of thumb is that all the water should be filtered within a maximum of 4 hours. If you have a 4×8 pool with 1,5m pool depth, the water depth is 1,4m. You then calculate the total water volume as 4x8x1,4 = 44,8m3. Divide that by four to determine the minimum flow the pool pump must handle: 44,8 / 4 = 11,2m3.

The pool pump for a pool with a volume of 44,8m3 should therefore handle at least 11,2m3. After that, review the pump performance curves.

If the pool pump is 1m above the water surface and 9m from the skimmer, a KSE75 is sufficient according to the curve above. However, you must account for all the elbow fittings in the system. Each 90-degree bend adds approx. 0,5m, so a KSE100, i.e., a 1 hp pool pump, is recommended for 4×8 m pools with 1,5m depth.

What types of pool pumps are there?

Just as pool heat pumps are available as inverter, i.e., stepless models, there are also so-called variable-speed pumps—VSP pumps—on the market. By running at a lower flow for a longer period, you save on electricity costs. The pump still has the power you need to backwash the filter. The cost of VSP pumps will pay off after 4–5 years of use, and it is important that the pump is of good quality.

Should you run the pool pump around the clock?

The answer is no. Although filtration is beneficial for pool water, you should turn off the circulation pump overnight. The reason to turn off the pool pump is that you do not want to mix the water—especially if the water is warm and it is cold outside. Otherwise, the water will cool during the night.
