What’s the Deal with Variable Speed Pumps?

With recent changes to DOE pool pump regulations and the ban of most single speed pool pumps, many people have been switching over to Variable Speed Pool Pumps. What’s the big difference between single speed and variable speed pool pumps?

Single speed pool pumps operate at a fixed speed, usually either 3,450 or 3,600 revolutions per minute (RPM), and use a lot of energy to move water through your pool’s filtration system. They are often loud and inefficient, resulting in higher energy bills and more wear and tear on the pump. Variable speed pool pumps, on the other hand, are designed to operate at different speeds, allowing you to adjust the flow rate to match the specific needs of your pool. This means you can reduce the pump speed during periods of low pool usage, which can lead to significant energy savings over time. Variable speed pumps typically run much quieter than single-speed pumps, and they also tend to last longer because they don’t have to work as hard.

In summary, the key differences between single speed pool pumps and variable speed pool pumps are that variable speed pumps are more energy-efficient, quieter, and offer more control over the flow rate.


There are many benefits that come with having a variable speed pump for your pool, including:

  1. Energy efficiency: Variable speed pumps are designed to adjust the speed of the motor to match the pool’s specific needs. This means that the pump doesn’t need to run at full speed all the time, saving energy and reducing operating costs.
  2. Cost savings: By reducing energy consumption, variable speed pumps can lead to significant cost savings over time. In fact, many pool owners report saving hundreds of dollars per year on their energy bills after switching to a variable speed pump.
  3. Longer lifespan: Because variable speed pumps don’t need to run at full speed all the time, they experience less wear and tear than traditional single-speed pumps. This can extend the lifespan of the pump and reduce the need for costly repairs or replacements.
  4. Quieter operation: Variable speed pumps often run at lower speeds, which can significantly reduce the amount of noise they produce. This makes them a popular choice for pool owners who want to enjoy a quiet backyard environment.
  5. Improved water quality: Variable speed pumps can help improve the overall quality of pool water by allowing for more efficient filtration and circulation. This can reduce the amount of time and chemicals required to maintain the pool and create a healthier swimming environment.

Overall, variable speed pool pumps offer a range of benefits that make them a smart investment for any pool owner looking to save energy, reduce costs, and improve the quality of their pool water.
