Choosing the right swimming pool filter pump

Published by Margaux Artigaud

The pump plays an essential role in a pool's filtration system, ensuring clean and healthy water is constantly circulating. However, an unsuitable choice can lead to major problems: cloudy and unbalanced water, excessive energy consumption, and higher maintenance costs.

Key takeaways:

  • On average, the flow rate of a pool pump varies between 6 and 18 m3/h.
  • The pump must be able to filter the entire volume of the pool in 4 to 6 hours.
  • Pool pumps account for approximately 30% to 40% of the pool's total energy consumption.
  • A variable-speed pump can reduce energy consumption by up to 60% compared to a single-speed pump.
  • A well-maintained pool pump can last between 5 and 10 years.

 

What is a pool pump for?

The main function of a pool pump is to ensure efficient water circulation and filtration. It keeps the water in constant motion, thereby facilitating the removal of impurities and the distribution of treatment products.

Key elements to consider when choosing a pump are:

  • Flow rate: the amount of water processed by the pump over time (m3/h)
  • Power: the pump's ability to create enough pressure to circulate water through the filtration system.
  • Energy consumption: the pump's energy efficiency, which directly impacts long-term operating costs.

Determine your pool's specific needs

How to choose a pool pump?

It is necessary to equip your pool with a filtration pump adapted to your pool and your needs. Several criteria need to be considered:

  • The volume of your pool: a small pool does not need as powerful a pump as a large pool.
  • The filtration flow rate: this flow rate must allow the entire volume of water to be filtered in 4 to 8 hours.
  • Your additional equipment such as heating and automated treatment systems can influence the choice of pump.

How to calculate the necessary power of a pool pump?

The power of a pump is calculated mainly based on the flow rate required to filter the water. The pump must be able to filter all the water in a maximum of 4 to 6 hours.

Flow rate (in m³/h) = pool water volume (m³) / filtration duration (h)

This means that for a 40 m³ pool with a 6-hour filtration cycle, the recommended flow rate is 6.7 m³/h.

What pump power do I need for my pool?

Pump power is expressed in HP (horsepower) and must correspond to the required flow rate:

  • Pools < 40 m³: 0.5 HP to 1 HP pumps
  • Pools between 40 and 80 m³: 1 to 1.5 HP pumps
  • Pools > 80 m³: 1.5 HP pumps or more.

 

Making the choice: fixed-speed or variable-speed pump

Why choose a classic filtration pump?

Fixed-speed pumps are the most common because their initial purchase cost is lower, and they are simple to install and maintain. However, their energy consumption is higher, and there is no possibility of adjusting the power according to your needs.


Why choose a variable-speed pump?

Discover the advantages and disadvantages of a variable-speed pump:

Advantages:

  • Energy consumption reduced by up to 80%.
  • Less noise when operating at low speed.
  • Increased longevity.
  • Adjust power according to your needs.


Disadvantages:

  • Higher purchase price.
  • Sometimes more technical installation.

 

Evaluating eco-responsible pump trends

What is the typical energy consumption of pool pumps?

Consumption depends on several factors:

  • Pump power (generally between 0.5 and 3 HP)
  • Operating time (varies depending on the season)
  • Annual usage duration (typically 4 to 6 months per year)

To calculate the precise consumption of your pump:

Power (kW) x Operating hours x Days of use

What are the advantages and disadvantages of eco-responsible pumps?

Advantages:

  • Reduced consumption for limited environmental impact.
  • Long-term payback through energy savings.
  • Innovative technologies: more efficient motors, recyclable materials.

Disadvantages:

  • Higher initial cost.
  • Sometimes more limited compatibility.

FAQ

Where should the filtration pump be placed to minimize noise?

Place it in a stable, sheltered location away from living areas. Variable-speed pumps, which are quieter, are ideal if the technical room is close to frequently used spaces.

Are filtration pumps compatible with salt treatment?

On Poolplanet, all offered filtration pumps are compatible with salt treatment.

Which pump to choose for a small pool or an above-ground pool?

Opt for a low-power pump, suitable for a sand or cartridge filter. For inground pools, prefer a pump with a large body to store more debris.

Can a single-speed pump be converted into a variable-speed pump?

Yes, thanks to an Isaver +, a speed controller to be installed between the control box and the pump.

What are the main criteria for choosing a filtration pump?

The criteria are maximum flow rate, filtration quality, and noise level.

How to reduce pump energy costs?

Use a variable-speed pump to adjust the speed to your needs. Otherwise, run it during off-peak hours and perform regular maintenance.

How often should the pump be run?

Run the pump to filter the entire water once a day, for about 8 to 12 hours, depending on the pool size and outdoor conditions.
