Divide the pool volume by the number of hours that you would want the pump to be running, so that would be 65,947.5 divided by 6. This would give you 10,991 which means your pump should be able to turn around this much water in 6 hours.
Consequently, how do I calculate my pool volume?
Length x width x depth x 7.5 = volume (in gallons)
Length times width gives the surface area of the pool. Multiplying that by the depth gives the volume in cubic meters. If you’d like to find the pool volume in gallons, multiply your results by 7.5, as there are 7.5 gallons for each cubic foot.
Accordingly, what is the flow rate of a 1hp pool pump?
How do I calculate the gallons in my pool?
Length x width x average depth x 7.5 = volume (in gallons)
Length times width gives the surface area of the pool. Multiplying that by the average depth gives the volume in cubic meters. If you’d like to find the pool volume in gallons, multiply your results by 7.5, as there are 7.5 gallons for each cubic foot.
Beginning with ‘SP’ followed by four numbers, sometimes ending with a suffix of numbers and letters, is how Hayward identifies most of their products. After you’ve found and copied down this number enter it into Inyo’s “Keyword or Part #” search, the result will be the direct replacement for your pump motor.
You might think bigger is better in terms of pump size, but a pump that is too big can cause serious problems. In the example above, the pool’s average depth is 8 feet. Now use the formulas below to determine the volume of water in your pool.
This product by Hayward is a 1.5hp pool pump designed to pump up to 90 GPM in most pools. It requires less maintenance and is highly efficient.
For each 1.5 inch intake line, the maximum flow into the pump will be 42 gallons per minute (GPM).
A Worthwhile Investment
Even at a higher initial cost than single-speed pumps, the best variable speed pumps are the superior investment because they offer prolonged filtration, more water turnover, and lengthier sanitation durations. These benefits make it easier to maintain your pool.
For a relatively small investment, a variable speed pool pump can reduce pool pump energy use by 50% to 75%. The majority of the savings is derived from a variable speed pump’s ability to reduce the rpm of the motor, thus reducing energy use.
HOW MUCH WILL YOUR NEW PUMP COST YOU TO OPERATE?
|Pool Size||Required Flow||Cost Per Hour|
|16,000 gallons||25 GPM||2.6 cents|
|24,000 gallons||35 GPM||3.65 cents|
|30,000 gallons||42 GPM||5.0 cents|
|36,000 gallons||50 GPM||8.3 cents|
30,000 gallons ÷ 24 hours = 1250 gallons/hour.
Pool owners often mistakenly believe if they choose a 2 HP pump over a 1 HP pump, they are getting double the performance. This is simply not true. In this scenario, you will get only about 15% more flow from the 2 HP model. But the amp draw of the larger pump will be significantly higher, raising your electric bill.
30,000 gallons ÷ 24 hours = 1250 gallons/hour.
So to answer the question, yes, you can replace your 1hp pool pump with a 1.5hp pool pump, but only if your situation calls for it. If you’ve determined that your current pump is too small for your pool, then we’ll suggest replacing it with a larger ECO pump like the Water TechniX Pump Alpha ECO.
A 15,000-gallon pool needs about 20 GPM output if we want to run it 24 hours per day. Most people run their pool on an 8-hour on/16-hour off (stagnant) cycle.
Calculate Flow Rate and Turnover
Flow rate is the number of gallons the pump moves per minute, and turnover is the minimum about of time to circulate all water through the filter. Your 25,000-gallon pool needs an output of 52 gallons per minute to circulate the water once every eight hours.
Number of submersible well pump stages determine pump lift capacity
|Table of Submersible Pump Stages vs HP vs Total Dynamic Head vs. GPM Flow Rate Capacity|
|Water Pump HP||Nr. of Pump Stages||GPM Flow Rate Capacity|
|1 1/2 HP||11||4 – 40 GPM (varies by TDH)|
|2 HP||14||4 – 42 GPM (varies by TDH)|
|3 HP||19||4 – 43 GPM (varies by TDH)|
Round Above Ground Pool:
For pools up to 24 Ft Round, use a 1 HP pool pump. For pools over 24 Ft Round, we recommend using a 1.5 HP pool pump.
When it comes down to it, both pumps have their own strengths and weaknesses. The Hayward EcoStar has better energy efficiency and the Pentair IntelliFlo has a reputation for longevity with a proven track record. It’s a close battle between the two pumps and it really comes down to personal preference.
However, it is important to note that a variable speed pool pump should ideally be running 24 hours a day to ensure proper and optimal water circulation. When your pool pump is not running, the water is sitting stagnant in your pool allowing bacteria to survive and grow.
The filtrations system can operate at low water flow with typical motor speeds around 1000 RPM or less depending on the size of your pool and how long you want to run the pump. Suction cleaners typically run at around 2200-2400 RPM.
