Why you should use an Eco-Friendly Variable Speed Pool Pump

When deciding to replace your existing pump with a more energy efficient pump you should look for a pump that uses variable speed technology. Variable speed pumps are Eco-friendly and energy efficient products that take advantage of the Pump Affinity Law to deliver incredible energy savings.

The Pump Affinity Law describes the relationship between the flow, speed, and power of centrifugal motors commonly used in swimming pools, spas, and water features. The key points of this law are listed below

  1. A pump at full power (100% Speed) will deliver 100% flow
  2. A pump at half power (50% Speed) will deliver 50% flow
  3. A pump running at half power will reduce resistance in plumbing by 75%
  4. When the speed of a pump is reduced to 50% power the power consumed is only 1/8 of full power

 

Here is an example of how this law would apply in simple terms:

Conventional Pump

  1. Pump running full speed at 3450 RPM
  2. Pump is flowing 80 GPM
  3. Power Consumed (22) 100 Watt Light Bulbs or 2.2 kilowatts per hour
  4. Run time 8 hours per day for total of 17.6 Kilowatts hours per day
  5. Cost of power at .15 cents per kilowatt hour equals $2.62 per day to operate

 

Intelliflo Pump Using The Pump Affinity Law

  1. Reduce speed to 1735 RPM
  2. Pump is flowing 40 GPM
  3. Power consumed down to (2.75) 100 Watt Light Bulbs or .275 kilowatts per hour
  4. Run time 16 hours per day for a total of 4.4 Kilowatts hours per day
  5. Cost of power at .15 cents per kilowatt hour equals .66 cents per day to operate

 

This example shows a savings per month of $58.80. That’s almost a 75% reduction or $705.00 dollars per year in cost of operation.

The real benefit here is that depending our you application you can further reduce the speed an experience even greater savings using the Intelliflo pump and applying the principles of The Pump Affinity Law.
