Variable speed pool pumps and drives

What is variable speed filtration?

Variable speed filtration is based on a simple principle: adapting the pump's rotation speed to the needs of the pool. Unlike conventional pumps that run at a fixed speed, these models allow for speed variation to optimize energy consumption and improve filtration quality.

Thanks to a permanent magnet motor, the pump adjusts its speed according to the situation, expressed in revolutions per minute (rpm). At low speeds, water circulates slowly, allowing for finer and more efficient pool filtration. At faster speeds, particularly during backwashing or periods of heavy pool use, the pump operates at full power for peak cleaning.

Some pumps are equipped with a touch control panel allowing for easy adjustment of speeds and filtration programs. These models can be single-phase or three-phase, depending on your pool's electrical installation.

Variable speed filtration is therefore an effective solution that allows for significant improvement in several aspects: energy saving, noise reduction, and better efficiency of the filtration system.

Why choose a variable speed pump?

A variable speed pump can achieve up to 80% energy savings compared to a traditional fixed speed pump. This type of pump automatically adjusts its flow rate according to filtration needs, thereby reducing electricity consumption.

In addition to savings, variable speed technology improves water quality. By optimizing filtration speed, it ensures homogeneous circulation and better water flow through the filter, which more effectively eliminates impurities.

The other advantage is noise reduction. Unlike conventional pumps, which run at full speed constantly, a variable speed pump often operates at a reduced speed, thereby decreasing noise pollution.

Finally, it extends the lifespan of your filtration system by limiting equipment wear thanks to smoother operation that is better adapted to the actual needs of the pool.

How to choose a variable speed pump?

The choice of a pool pump depends on several essential criteria:

Pool volume
It is important to choose a pump capable of filtering all the pool water in approximately 4 to 6 hours. To calculate the required flow rate, divide the volume of your pool by 4. For example, a 40 m³ pool requires a pump of approximately 10 m³/h.

Energy performance
Opt for a pump with a high-efficiency motor to maximize energy savings and better filtration quality. Some pumps display a performance label that certifies their low consumption.

Features
Some models offer advanced programming, intuitive control interfaces, or even home automation connectivity allowing you to control the pump remotely from your smartphone.

Noise level
A quiet pump improves user comfort, especially if your pool is close to your home or your neighbors'.

Note that a silent variable speed pump is generally more expensive to purchase than a fixed speed pump.

What is the electricity consumption of a variable speed pump?

The consumption of a pool pump depends on several factors:

• The motor power (expressed in kW)
• The daily operating time
• The filtration speed used

A fixed speed pump generally runs at full power (1,500 to 2,500 W) continuously, while a variable speed pump adjusts its consumption between 100 and 1000 W maximum according to needs --> guaranteed energy savings!

On average, a variable speed pump consumes between 100 and 200 kWh per year, compared to 600 to 1,500 kWh for a classic pump, which represents significant electricity savings on your bill.

How does a variable speed pump work?

Unlike a traditional pump that operates at a single speed, a variable speed pump has a variable frequency motor that allows it to adapt the impeller's rotation speed.

The user can choose from several operating modes:

• Low speed: ideal for daily filtration, it consumes little energy and optimizes water quality.
• Medium speed: recommended when using a hydraulic cleaner robot or on a sunny summer day.
• High speed: used occasionally for filter backwashing or when the pool is heavily used.

This real-time adaptation allows for more efficient operation while enabling you to save electricity.

What variable speed pump models are available?

There are several brands and models of variable speed pumps, each offering specific features.

At Poolplanet, we offer you the best variable speed pump that is efficient, economical, and accessible: the Pentair Swimmey VSE. On our website, you will find brands such as Aquagem and Pentair, recognized for their quality; these silent and high-performance pumps are benchmarks in variable speed technology.

For all owners of fixed-speed filtration pumps, it is also possible to connect a speed variator to adapt the motor speed to your needs. This device is the Isaver+ and is compatible with all available classic filtration pumps, allowing you to achieve real energy savings by switching to variable speed filtration. With Isaver+, it's also possible to make your current filtration pump quieter.
For all tech enthusiasts, it is also possible to connect your variable speed pump to your smartphone, so your pool's filtration time and speed can be easily programmed from anywhere. For this, you will find the Antea VS, a Vigipool antenna that continuously sends your pump's data to the Tild VP control box.

What is the lifespan of a variable speed pump?

A pool pump has an average lifespan of 8 to 12 years, depending on several factors:

• The quality of the electric motor and components
• Regular maintenance of the equipment (pre-filter cleaning, seal inspection)
• The installation environment (reliable shelter, guaranteed weather protection, technical room)

Variable speed pumps have a longer lifespan than conventional models because they operate at reduced power most of the time, thereby limiting the wear of mechanical parts.

How to install a variable speed pump?

Installing a variable speed pump is relatively easy and can be done in a few steps:

1. Cut the power supply to avoid any risk of electrocution.
2. Dismantle the old pump by unscrewing the hydraulic and electrical connections.
3. Install the new pump by positioning it on a stable support and connecting it to the filtration system pipes.
4. Electrical connection: follow the manufacturer's instructions for a secure connection.
5. Speed programming: adjust the speed according to the pool's needs.

For optimal installation, it is advisable to call on a professional who will ensure the correct sizing of the components to guarantee easy access to your pump. Configuring a variable speed pump remains accessible by referring to the manual.
