Single speed or variable speed pump – Which one to select?

Posted by John Smith on August 16th, 2019

The Energy Efficient Pool Pump is vitally important in the functioning of a swimming pool and is a key ally to guarantee a high quality of bathing.

Working many hours a day, the filtration pump ensures that the water is renewed and filtered.

It is possible to choose a traditional single speed pump or a new generation variable-speed filtration pump. The two options have different performances and entail a different initial investment, so it is important to consider your priorities to choose the filtration pump suitable for you.

The filtration pump is a vital organ of your pool:

The Variable Speed Pool Pump is responsible for water intake and discharge. It sucks the pool water through the skimmers and the main drain sends it to the filter where it is filtered, purified and then returned to the pool through the return nozzles. The impurities are trapped by the filtering material of the filter.

Variable speed pumps: What is the difference and how are they used?

A traditional filtration pump runs at a constant speed, which means that, regardless of the water cleaning or how often the pool is used, the energy consumption will be the same, and the noise level will be constant.

Equipped with a permanent magnet motor, the variable speed pumps can instead operate at different speeds, to adapt to the specific needs of your pool.

For example:

- For a backwash, high speed should be chosen.
- For a pool without swimmers and clean water, a minimum speed.
- For intensive use of your pool or during hot periods, a higher speed.
- If a hydraulic cleaning robot is used, the maximum speed to improve cleaning efficiency, etc.
