Replace Your Variable Speed Pool Motor

by Pool Builders on 07-07-2013 in Articles

Are you tired of your noisy, old, inefficient pump? Are you looking to upgrade to a new swimming pool pump? Then there are a few things you should know before deciding which one to get.

First things first, you need to make sure your pump is the right fit for your pool. While most high-end variable speed pool pumps can be adjusted to achieve the optimal flow rate, you will need to know the size of your plumbing (1-1/2", 2" etc.).
And this decision is NOT all about horsepower. Many pumps can achieve the maximum GPM (gallons per minute) required for your pool, but may still run inefficiently because of your system's dynamic head. If you don't know how to read a pump curve chart, then don't hesitate to seek help from a professional. This is a big investment, and any reputable brand or local store will be happy to get you going in the right direction.

Additionally, horsepower isn't always an accurate display of a unit's efficiency. Most of the motors in high-end variable speed pool pumps, like the ones made by Jandy and Pentair, have horsepower that has been limited by their controllers. And just because a motor is potentially more powerful than another, doesn't mean it is handling the power it is using in the most efficient manner. In most cases you won't need the extra power, so you should focus on compatibility and kilowatt usage per hour. At the end of the day, these are what determine your costs, and how well your filtration system works with your pool.

Next, be prepared for the costs of upgrading. If you are coming from an older system, it may not be compatible with your new technology. Be ready for the cost of installation, as well as any new equipment you may need.

As a rule of thumb, try to use filtration products like pumps, filters and controllers from the same brand. Incompatibility issues tend to arise when trying to combine controllers, filters and pumps from different companies. For example, use a Hayward pump with a matching D.E filter and control panel.

Use a name you can trust. The longer a brand's products have been in the field, the easier it is to find replacement parts. Keep this in mind, because you do-it-yourselfers can save a lot of money buying and maintaining used pumps. Variable speed pool pumps with sealed permanent magnet motors have a reputation for durability, as well as a long shelf life. Without having to worry about the motor dying, the rest is just replacing bearings, fittings, and other small pump parts. It's not as hard as you think to repair or replace pump parts, and there are many tutorials and videos online that can help you.

Don't go with the cheap alternative.

I know the price of a new variable speed pool pump can be expensive. But it's a price that comes with a great ROI, and a good pump usually pays for itself within three years. And in addition to that, power companies across the nation are offering rebates for installing energy-efficient pool pumps. Don't look at the initial cost, look at how much you will be spending over the next five years if you move forward with another energy-draining pump.
