Pool Pump Motors

While keeping the pool’s sanitation, free of debris and clean, the pool power pump motor pumps the water from a pool, all the way through the filter and then circulate it back into the pool again.


Pool operations

It is strongly recommended by the pool builders to run your pool pump at least for two cycles per day. This act is essential to keep the water sanitation high. It is important to determine one cycle duration as accurately as possible using the steps outlined below.

Total Head – this is the length of the pipe from the pump to the pool. You will be required to use your tape measure to determine the length or ask for assistance from the pool builder or the pool service technologist. Once you calculate you add 10% to the buffer.

Determine The Pool Water Volume
Pool Volume Calculation

Use Pool Volume calculators

Or The Manual Way

For Constant Depth pools: Rectangular or Square. This is calculated by multiplying the width by the length to give you the surface area of the pool. When multiplying the surface area by the depth, you get the volume in cubic feet. And since you know that there are seven gallons of water in a cubic foot, then by multiplying the pool’s cubic feet by 7.5 you will arrive at the volume of the pool expressed in gallons.

To Determine the Water Flow: this depends on the horsepower of the pump that typically ranges from 60 – 100GPM (Gallons per Minute). You will be required to refer to the manufacturer’s chart.
A common pool holds 18,000 to 20,000 gallons of water. By taking 20,000 gallons and 80 GPM( 4800 gallons per hour, here is the calculation.
20,000 / 4800 – 4.16 hours per cycle and this can be rounded off to 4.5 hours.


Most pool providers recommend that the pump is run for a duration of between 6-8 hours per cycle through experience. This will sound overemphasized if you are trying to save on electricity energy bill, minimize the pool pump noise level for you and your neighbors. Considering the duration mentioned above, you are likely to save almost a half in electric bill and length. To save more money, you will be required to contact the utility company to determine the peak time and avoid them as much as possible.

Ensure to check the pool pH to maintain a proper cycle duration. In uncontrollable conditions like rain will require the pump to run for one extra hour.

Pool Pump Motor Vibrations

1. Closely monitor your pump motor as it runs. Try to look for movements and vibrations along the pump base. If you find loosened bolts on the pump, use an adjustable wrench to tighten them and secure the pump to the concrete pad underlying it for noise reduction.
2. Ensure you place our vibration pads beneath the motor pump base to isolate the concrete pad from the pump is essential for noise reduction.

Clean The Pump’s Basket Motor Skimmer

1. Turn off the pump power
2. Remove the transparent lid to expose the pump motor strainer basket.
3. Pull the strainer basket from the pump and clean it free of any debris and dirt. A small debris inside will cause vibration and increase pool pump noise levels.
4. Replace the lid and fasten it
5. Turn the power pump on.
