Top 5 Reasons to Convert Your Pool Pump Motor to Variable Speed
The benefits of upgrading to a variable speed pool pump motor are a win/win for pool owners and the environment
In-ground residential pools in the United States consume around $1.5 billion in energy costs per year, making pool pumps one of the biggest energy users in a home. Single-speed pumps typically run at high speeds and around the clock, over-circulating water and wasting precious energy and money. A variable speed pump motor can circulate water at the minimum turnover rate for water quality at lower speeds, thereby greatly reducing the energy needed by up to 80%.
1. Energy Savings
For a relatively small investment, a variable speed pool pump motor can pay for itself in energy savings alone. The Pump Affinity Law can be used to explain the relationship between motor speed, flow rates, and energy consumption. As motor speed is reduced, the flow rate is as well. This relationship to energy consumption (watts) is not linear, though. When motor speed is cut in half, the flow rate is cut in half. However, the power consumption is reduced to 1/8 of the original consumption. Table 1.1 shows the dramatic energy savings associated with running a motor at lower RPM’s.
States, such as California through its Title 20, have recognized the energy saving impact that variable speed motors can have on the environment. Variable speed motors are increasingly preferred by regulatory agencies, over single and two-speed motors, for their ability to conserve energy. Additionally, the U.S. Department of Energy has mandated that pool pump replacements after July 2021 be variable speed.

2. You Don’t Need To Replace The Entire Pump
Variable speed pump replacement motors can be installed on existing single-speed pumps. Upgrading to a variable speed motor is all that is necessary to convert pools into high-efficiency systems. Service technicians should select the variable speed motor that is appropriate for the size of pool, plumbing and pump. Installation is simple without the need for additional plumbing or wiring.
3. More Affordable Than A Pump Replacement
Upgrading to a variable speed motor on your pool pump is more affordable than replacing the entire pump. Motors on a pump can be replaced without the need to remove the existing pump. This simplified approach saves the service technician time and you money.
4. Variable Speed Motors Are Quiet
The slower circulation rates of a variable speed pump equate to a noticeably quieter motor. A pump running outside of a bedroom window or during a pool party will no longer be the loud nuisance that you may have come to accept as a normal part of pool ownership.
5. Variable Speed Motors Are Built To Last
Operating at lower speeds also lowers the temperature of the motor, extending the life of the motor. A variable speed motor’s totally enclosed fan cooled (TEFC) construction equates to a longer life and less maintenance compared to a traditional open drip proof design.
The VGreen® line of variable speed replacement pump motors by Century Motors offers an integrated user interface with fully programmable schedules and overrides. Using the VLink® Wireless User Interface that connects the VGreen motor allows you to use your mobile devices to set, adjust, and monitor pump motor schedules. The program flexibility allows the you to monitor and manage energy consumption as well as set custom overrides for parties and cleaning.
Upgrading to a VGreen variable speed motor will lower the cost of pool ownership through energy savings of up to 80% without replacing the pump. These motors run cooler, quieter and last longer. Owning a pool with a variable speed motor just became more affordable and is better for the environment.
