Pool Pump Motors
If you have a noisy pool motor or a motor that is no longer working, we can repair or rebuild your existing motor. In cases where the motor may be beyond a realistic cost effective repair, we carry a full stock of install ready rebuilt add “new” motors. This will often allow you a less expensive option than replacing the entire pool pump assembly.
We also carry variable and two speed replacement motors that can be a direct replacement for your existing single speed motor. These motors work for most typical pool applications and offer tremendous energy savings over conventional old style motors. As a bonus they’re much quieter as well. So neither the price nor the noise will keep you up at night.
Your swimming pool pump is the heart of your pool’s equipment system. It plays a pivotal role in keeping your Arizona pool healthy, clean and sanitary. Without it, you would have nothing but a nice green swamp in your backyard! The pump is responsible for circulating the water from the pool, into the filter where particles are trapped, through the heater if equipped, and returning to pool.
A pool pump’s ability to move water is measured in horsepower (HP). There are several different HP outputs that can be used and the correct pump size is determined by several factors. The size of the pool, the other equipment or water features in pool and the plumbing size and length are all considered when sizing a pool pump. The goal with residential pool filtration is to run the volume of the pool through the filter at least once a day. Over-sizing a pool pump can result in not only excessive turnovers and wasted energy, but will also result in excess wear and tear on the equipment specifically the filter and heater.
The ideal sized pool pump will provide sufficient turnover of the pool while moving the water through the plumbing at a speed that will not create excessive friction or resistance. Resistance as water moves through the plumbing is referred to technically as hydraulic head and is measure in feet. The less feet of head resistance the more efficient our pump will perform as it will not overwork itself. This results in a pump that will last longer.
A standard induction motor single speed pump was once the most common type of pump used in the industry. They run at one set speed and consumed a good deal of energy. Although not as popular there are also two speed pumps. These two speed pumps also had an induction motor but had the ability to run at a very low speed as well as the normal high speed. These pumps running on low speed could run the pool for the bulk of the day and provide a real substantial energy savings due to a very low energy draw when on low speed setting. They were usually controlled by a second external timer to run a few hours on high speed to operate a suction cleaner or in floor pool cleaning system. The Pentair WhisperFlo was a popular two speed pool pump.
In about 2005 the first variable speed design pool pump was introduced by a company in California called IKERIC. While IKERIC did not stay around long, Hayward, Pentair and then Jandy all introduced their own models of VS pumps.
The variable speed pump used a different motor type called permanent magnet synchronous motor or PMSM for short. The PMSM could be controlled by a drive that had the ability to speed up or slow down the motor to any set point. This meant that the amount of water moved through the pool could be increased or decreased as needed. A wonderful benefit of these new variable speed pumps was that they could move the same amount of water as a larger horsepower single speed pump, but do it at a fraction of the energy use. Whereas the single speed pump may have used 2000 watts an hour, the variable speed pump would use less than half that to perform the same job.
As the speed setting on the VS pumps was further decreased, the friction or head resistance in the system is also decreased. Also, as the speed is decreased the energy use decreases to the point where a typical VS pump can move 40 gallons of water a minute at an incredible low 250 watts an hour. That’s a couple lightbulb’s worth of power and almost a tenfold decrease in energy use of a typical single speed pump. Since the water is running slower through the system, we can run the pump longer if needed and put less wear and tear on the equipment while still saving in our energy cost. A standard variable speed pump installation whether it is a Hayward EcoStar, Tristar, or a Pentair IntelliFlo typically saves $60 off the typical Scottsdale homeowner’s electric bill.
In 2014 Arizona passed the Title 44 Energy Standards Regulations. Part of these new regulations require any pool filter pump replacement over ¾ HP be of either a two speed or VS design. All licensed pool repair personnel must abide by this law.
While the VS pumps are a bit pricier, the installation cost is greatly offset by the energy savings garnered. Also in the Phoenix area both SRP and APS power utilities offer a $100 rebate on these pumps. If your current pump needs replacement but the cost of a VS pump is just a little out of reach, a good option would be to have a two-speed motor installed on your current pump to replace the dead motor. No external timer is needed on these newer two speed pumps as they come with a digital timer. The AO Smith 2Green motor is the one we recommend.
While they do not provide the same programming flexibility or energy savings as a VS pump, they still do save energy costs and comply with the Title 44 regulations as well.
Bottom line is that there are some great choices that will help you get the maximum life out of your pool equipment, and save you money at the same time. That’s a 360° win.
