What Are the Pros of Using a Variable Speed Pool Pump?


After this date, if you need a new pool filtration pump (more than 1.0 Total Horsepower), you must use a variable-speed pump. There are many advantages of variable speed pumps, sometimes VS pumps. The money you save is enough to recoup your investment quickly. You should buy variable-speed pool pumps for these reasons.

Energy Savings on a Grand Scale

The Department of Energy has shown swimming pool pumps are among the top five residential energy drains. Conserving energy benefits, not just the planet but also your bank account. Low-speed motor operation of a variable-speed pump results in reduced amp and wattage consumption, resulting in cost savings. By operating the pump for a more extended period each day at lower speeds, you may reduce energy consumption by 50–80% compared to a single-speed pump. The beauty of pools with variable-speed pumps is that you may adjust the pump’s speed to match your specific system. You may optimise your energy savings by adjusting the VS pump’s settings to run cleaners, heaters, water features, and even connected spas.

Effortless, Near-Silent Function

Since a variable speed pump’s permanent magnet motor operates at lower speeds, it is quieter. At lower speeds, a VS pump may be almost inaudible. Higher pump speeds do not significantly increase the noise level of a VS pump. Compared to regular pumps, which generate about 60-70 dB of noise, the quieter variable speed pumps register between 40 and 50 dB due to a variation in motor design. Worn-out bearings cause the majority of cases of excessive motor noise. In contrast to the standard pump motor bearings, the inverter duty bearings used in VS pumps are far more robust and long-lasting.

Maximum Productivity for Intended Uses

Filtering, heating, cleaning, and operating spas and water features may all be optimized with the help of variable-speed pumps. There is just one speed (3450 RPM) available on most typical pump motors, which limits your ability to customise your pool’s settings. One of the main benefits of variable speed pumps is the ability to “tune in” the ideal speed for various applications. Specific water flow rates are optimal for water features. Similarly, reduced flow rates improve heating systems and pool cleaners’ efficiency (and cost-effectiveness). Even though filtration flows slower than the pump’s other capabilities, it nevertheless generates sufficient velocity for some skimmer suction.

Increased Capacity for Water Filtration

When filtering water, slower speeds are preferable. Slowing the flow velocity makes it simpler for the filter medium to capture and hold onto the tiny particles. There may be some filter bypass or tiny particles returning to the pool unfiltered for pools with a conventional pump running continuously at 3450 RPM. If the flow rate is lowered, your filter might perform better with less pressure drop. Filter media wear out more quickly when subjected to the everyday stress of increased flow rates; therefore, reducing the flow rate helps to preserve it for longer. Keeping your pool clean and preventing the water from becoming stagnant is easy when you have a VS pump working virtually continuously at modest rates.


Timer clocks or switches mounted on a pole near the pump are the most common means of automation for ordinary pool pumps. However, modern variable-speed pumps include an embedded computer instead of the traditional mechanical time clock, enabling you to navigate menus to set the desired pump speed and schedule its use. Having a variable speed pump comes with several advantages.
