Transcript:How to Choose the Right Pump for Your Swimming Pool

Hi, I'm Ron Coker, Jr. with Artistic Pools for About.com. We're talking today about different types of pool pumps and how to size them appropriately.

Single and Dual Speed Pool Pumps

There are basically three different types of pool pumps: you've got single speed, dual speed and variable speed. A single speed pump is just that. It has one speed and one horse power so it can service one application. A dual speed pump has two different settings. One is a higher setting to operate all the functions of the pool the other is a lower or more energy efficient setting which runs at a lower speed or horsepower to give you a little more energy efficiency and to be a lot greener.

Variable Speed Pool Pumps

The most efficient pool pump on the market today is a variable speed pump. You can program variable speed pumps in four different settings. You can also ramp up and down as it senses the flow resistance as the filter gets a little bit clogged and it adjusts itself to meet the needs of the desired program.

Sizing the Right Pool Pump

To size a single speed pump, you first need to determine the rate of flow and also the total dynamic head of the system. Rate of flow is based on the volume and turnover rate that you're looking for, which is the amount of time it takes one gallon of water to cycle once through the filtration system. The total dynamic head is the resistance to flow in the system and that's determined by pipe size, and also the length of the run and the number of 90's and 45's you have on the system. Once you have these two factors, you can go to a pump curve which graphs the two together and you can determine the size or horsepower of the pump needed to supply energy for the desired result.
