For example, if the required motor speed is 900 rpm and the nominal speed is 1,000 rpm, the answer is 0.9. Multiply your answer by the nominal flow rate for the pump to give the converted flow rate. For example, if your answer is 0.9 and the nominal flow rate is 4,200 GPM, the converted flow rate is 3,780 GPM.
Herein, what is a good schedule for a variable speed pool pump?
Variable-speed filter pumps should run longer, based upon the operating speed. Most pool owners run their variable-speed pump 12 hours per day (3-4 hours on high speed for the pool cleaning system and 8-9 hours on low speed for filtration).
Furthermore, how long should I run my Pentair IntelliFlo pump?
The rule of thumb is generally 8 hours, although it could be anywhere from 6-12 hours, depending on your pool’s size. Each pool is unique, so to keep your pool pump efficient and effective, you need to figure out exactly what your pool’s turnover rate is.
How do I find the GPM of my pool?
Divide the total gallons of water in the pool by the turnover rate in hours. Ideal turnover rate is between six and eight hours. To run the pump less time each day, lower the turnover rate. This will give you the gallons per hour or GPH.
What is the formula to calculate GPM?
The formula to find GPM is 60 divided by the seconds it takes to fill a one gallon container (60 / seconds = GPM). Example: The one gallon container fills in 5 seconds. 60 / 5 = 12 GPM.
How fast should Pentair pump run?
Generally, I run my equipment at 1700 RPMs for 10 hours. I run this with the saltwater generator set at 50% for 10 hours. In my case, 1700 RPM’s is the minimum I can do to reliably activate the saltwater generator and filter the pool.
How many rpms should I run my pool pump?
Suction cleaners typically run at around 2200-2400 RPM. Heaters require 20 to 40 Gallons Per Minute (GPM) so might run at around half speed or a little higher. You would probably want to run your Spa at up to full speed, 3450, for maximum effect.
How many RPM should a Pentair pool pump have?
For example, for the first few days, you might run the pump at 2500 RPMs to see what your pool looks like. Next, you might dial it down to 1600 RPMs. If after a few days your pool starts to look cloudy or hazy, you can set the pump to run at 2000 RPMs.
How do you calculate the flow rate of a hydraulic pump?
Theoretical flow is calculated by multiplying the pump’s displacement per revolution by its driven speed. So if the pump has a displacement of 100 cc/rev and is being driven at 1000 RPM, its theoretical flow is 100 liters/minute.
How many gallons per minute should I set my pool pump?
Turnover Time – time to move entire capacity of pool through filter. Flow Rate –
| Pool Size (US Gallons) | Turnover (Hours) | Minimum Flow Rate |
|---|---|---|
| 35,000 | 10 Hours | 58 GPM |
| 24,000 | 8 Hours | 50 GPM |
| 24,000 | 10 Hours | 40 GPM |
| 18,000 | 8 Hours | 38 GPM |
What size pump do I need for a 30000 gallon pool?
So, for a 30,000-gallon pool that runs continuously (24-hours), the formula is: 30,000 x 2 ÷ 24 ÷ 60 = 41.6 or rounded up it’s a 42 GPM minimum flow rate. To establish the max flow rate needed for your swimming pool, I like to go by filter surface area.
How much power does a Pentair pool pump use?
IntelliFlo operates at an average of just 1/6th of a horsepower, using about 200 watts of energy. Exclusive, variable speed capability builds potential savings up to 85%.
What size pump do I need for a 15000 gallon pool?
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.
What is RPM in pool pump?
Most pool pump motors operate at 240 volts and generate 3,450 rpm when running at full speed (based on standard U.S. electricity, which is 60hz). A variable-speed pump motor offers an operating range of 172 rpm to 3,450 rpm.
How do you convert GPM to RPM?
Output Calculation
The ratio is 1 gallon for every 10 RPM, or 1:10. Now if you measure the pump’s output and find it has pumped 2.3 gallons in one minute, you can estimate its RPM is 2,300.
How many hours should I run my variable speed pool pump?
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.
How do you calculate the GPM of a hydraulic pump?
How to calculate a hydraulic pump fluid flow rate
- Flow (GPM) = (RPM x Disp) / 231.
- RPM = Rotations Per Minute.
- Disp = Pump Displacement in Cubic Inches.
- GPM = Gallons Per Minute.
How do you calculate pump speed flow rate?
How long should a variable speed pool pump run?
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.
What are the best hours to run your pool pump?
The best time to run your pool pump is during the warmest hour of the day; however, keep in mind that this means you will have higher energy consumption, which may lead to an increase in your electric bill. If you want to save on your energy costs, you can run your pool pump at night to avoid peak hours.
