Swimming Pool Pumps

The right pool pump keeps your water clean, clear and properly circulated, working alongside your filtration and heating systems to maintain perfect swimming conditions all season long. We stock a range of domestic swimming pool pumps, including energy-efficient variable speed models and single-phase pumps for home installations.

Why Are Swimming Pool Pumps Important?

A swimming pool pump is the heart of your pool system. It circulates water through your pool filter, helping remove dirt, debris and microscopic contaminants. Without proper circulation, water quickly becomes cloudy, unbalanced and vulnerable to algae growth. A quality pool pump also:

• Distributes chemicals evenly throughout the water
• Supports heating systems for consistent temperature
• Prevents stagnant water and contamination
• Improves overall filtration efficiency

Running your pump correctly ensures your pool water remains fully sanitised and safe to swim in.

Types of Swimming Pool Pumps

Choosing the right pump depends on your pool size, electrical supply and efficiency goals. Below is a breakdown of the main types available.

Single-Phase Pool Pumps (230V)

Single-phase pumps are the most common choice for UK domestic swimming pools. They operate on a standard 230V household electrical supply and are suitable for the majority of home installations. Best for:

• Small to medium residential pools
• Standard 100A consumer units
• Straightforward replacements

Three-Phase Pool Pumps (380–415V)

Three-phase pumps are typically used in commercial pools, leisure centres and large residential properties. They require a higher voltage supply and offer smoother operation under heavy load. Best for:

1. Large pool systems
2. Commercial environments
3. High-demand circulation setups

Pool Pump Speed Options

Energy efficiency and running costs largely depend on the type of motor your pump uses.

Single-Speed Pool Pumps

Single-speed pumps run at one constant speed whenever they are switched on. They are simple and reliable, but less energy-efficient compared to modern alternatives. Suitable for:

• Basic pool systems
• Budget-conscious installations

Dual-Speed Pool Pumps

Dual-speed pumps offer both low and high-speed settings. The lower speed is ideal for daily filtration, while the higher speed can be used for backwashing or vacuuming. Benefits:

• Improved energy efficiency
• Greater operational flexibility
• Reduced running costs compared to single-speed pumps

Variable-Speed Pool Pumps (Most Energy Efficient)

Variable-speed swimming pool pumps are the most advanced and energy-efficient option available. Using permanent magnet motors, they allow you to adjust flow rates to match your pool’s exact needs. Advantages include:

• Up to 80% energy savings
• Quieter operation
• Longer motor lifespan
• Lower electricity bills
• Automatic flow adjustment

For most domestic pools, a variable-speed pool pump provides the best long-term value.

How to Choose the Right Swimming Pool Pump

Selecting the correct pump depends on several key factors:

• Pool size and water volume
• Required turnover rate
• Existing plumbing configuration
• Electrical supply (single or three-phase)
• Budget and long-term energy costs

If you're upgrading an older pump, switching to an energy-efficient variable-speed model can significantly reduce operating expenses.

Swimming Pool Pump FAQs

How long should I run my swimming pool pump?

For most domestic pools, running your pump for 8–12 hours per day is recommended. In warmer weather or during heavy usage, longer run times may be necessary to maintain water clarity and prevent algae.

Can I install a swimming pool pump myself?

Yes, if you are a competent DIYer you can easily install a replacement for your pump. It will involve some plumbing work on the pipes and connecting the electrical supply.  If you don't feel you are competent enough, contact us, and we can find a pool engineer to do it for you. 

How do I maintain a pool pump?

To keep your swimming pool pump running efficiently:

• Empty the pump basket weekly
• Check for leaks or unusual noises
• Inspect the impeller for blockages
• Ensure adequate ventilation around the motor
• Clean or backwash your pool filter regularly

Routine maintenance extends the life of your pump and improves system performance.
