What Pump Speed Do I Need To Run My Salt System?

From www.swimmingpo... - See an example of the minimum speed to run you variable speed swimming pool pump to generate chlorine with a salt water chlorinator. The exact RPM value needed to close the flow switch for a salt water system will change from pool to pool and pump to pump so the manufacturer publishes minimum flow rates (in GPM). Watch this video to see real world examples of the pump RPM needed for Hayward salt systems or Pentair salt water chlorinators to function.

Thanks Steve,
I am in the pool industry in Australia. We have a legal requirement that the chlorinator cell has to be installed in a gas loop. The cell is high with the pipes exiting the cell and going straight down. The idea is that if the pump fails or the flow is lost, the hydrogen gas that is created collects in the cell and the cell then reads "no flow" and about five minutes later the chlorinator switches the pump off avoiding damage. I find with uneducated customers they run the pump so slow that the gas builds up and switches the pump off. I get a call complaining about the chlorinator is not working and the pool going green. The cell will work until it is no longer submerged in water. I normally sell people like that a normal pool pump and only sell the muti speeds to people who have some tech savvy. Like a lot of things in the right hands multi speed pumps are great but in the wrong hands they are a nightmare.
Steve, THANK YOU for a straight and simple video on a subject I've been researching! I had a salt pool, went to chlorine tabs (which I had on other pools) and now want to make the switch back to salt. But, I installed a variable speed pump which messed up my inline chlorinator (not enough flow) and wanted to make sure that the minimum 1,400 rpm I run the pump at on the long, low runs would work...It should thanks to your information. Sub'd.
Thanks for the video Steve. However, if you add a Pentair Mastertemp heater and check valve after the heater, you would need around 1600 to 1700 rpm to reach the 25GPM for a Pentair Intellichlor SWCG with a 2” line. That’s my case. Once I bypass the heater and check valve, I can definitely reduce the speed lower than 1600rpm and turn over the pool water 3x in 24 hours.
Definitely. And if you add something more like a rooftop solar or another peripheral devi e like AOP this will walk you higher and higher rpm for that same 25 gpm. Compare resistance to flow on the pump curve put out by the manufacturers of each pump. Ypu can then see how different models with different hydraulic design and other size would perform under similar head conditions. Every pool is unique. Much to consider.
The best info on the tube. Thank you sir
With my variable speed Pentair pump and Intellichlor salt generator, the red flow light doesn't go off until I increase my pump to 1750 rpm. My plumbing is 2" as well.
JESUS, WHAT A SET UP, SHEESH, OUT OF MY BUDGET, THATS FOR SURE
Would've been nice for you to add the flow switch and see if it did close. Another item to consider, is that the salt cell calcium build-up appears to happen quicker with lower flows/ lower pump speed. Which means acid clanging the salt cell more then the typical 3-month frequency.
That is good point. I was thinking of running my swg at 1400 rpm for about 5 hours average. At which speeds are you having clearly more calcium?
Steve, just wondering if you could make a video discussing the Hayward Tristar XE pumps. I can not set rpm only percentage of pump speed. I was told this was the pump I needed to be able to keep my aqua link rs operational.
Very helpful. I'm just starting up my pool and my pool guy says we aren't generating any chlorine from my Intellichlor system. We just drained and refilled the pool. I'm only running the pump and chlorinator for 6 hours a day. I run the pump at 1,800. I think I'll back it down to 1,000 and increase it to 8 hours to see if that helps. The salt cell is only about 2 years old and I take it off during the winter.
You need a flow meter and also look up the minimum flow rate for your salt cell. I think it is 20 or 25 gpm. You should be running your pump 25 hours per day. A few hours at higher speeds, double that at mid speeds and the rest of the 24 hour day at low speeds. Ideally you want to be generating chlorine at medium and.jigh speeds. Low-speed also would be good but your output on the salt system would need to be dialed back
@@Swimmingpoolsteve Thanks so much! I'll do that. All five "percentage" lights are flashing at the same time. We're going to ensure there is sufficient flow. Your information has been really helpful.
Is It needed another chemical additional when having a salt water chlorinator? Thanks
I have a hayward tristar variable speed pump w3sp3206vsp and a penrair intellichlor can I use the timer on the pump to turn on and off the chlorinator ?
My salt cell (aqua rite) produces chlorine at 600rpm with a tristar 900 with 2 inch pipe. With a clean DEP 80 filter.
So basically idle speed and next to nothing for power consumption.
@@Swimmingpoolsteve I am not sure how it is doing it really. Most pools I see need at least 1000-1200rpm
whatS a good run time for my salt chlorinator ? is 8 hours good a day in FL?
not sure you are asking the right question -- as I have been running my pump high enough to keep the flow switch open... but pretty sure it is too low to keep my cells from getting calcified (or whatever that white stuff all over my cells is).
That calcification is a normal part of salt cell function. Just clean it when it is getting scaled up. It ypu might have a point, which is higher flow rates probably get rid of at least some of that
@@SwimmingpoolsteveI can also imagine a higher LSI violation inside the cell with reduced flow....higher pH and or higher temperature maybe?
Thanks for your videos! Have a question, I just installed the hayward super vs pump and also running the pentair salt cell that has a flow light on it, green good, red low flow.
I'm at 1500 ram's and still getting red light. If I have to run more ram's for the salt cell I may have wasted $1500 for a vs pump.
Your advice?
Why is 1500 rpm the magic number that saves you money? Give it whatever rpm it needs to operate. The difference between 3450 (max speed) and 3100 rpm is HUGE. so 2400, 2200, 2000, 1800, 1600 etc ALL are going to give you a tremendous amount of flow, and highly efficient flow at that, for very little electricity use. You will definitely still save money.
@@Swimmingpoolsteve Thanks for the quick reply sir! It seems my salt cell needs at least 1700rpm's to run correctly so here is my current set up for day 1:
1700 rpm's 2pm to 6am/ down 4 hours then 3000 rpm's 10 am to 2 pm.
I will see how this works for a few days then adjust accordingly.
Again, thanks for your help.
@@Swimmingpoolsteve So another update after running my pool for 24hrs at 3000 rpm's for 4 hrs and 20hrs at 1700. $2.28 savings on my electrical bill! Awesome savings and a cleaner pool! Thanks for all your help sir!
What percentage of chlorine production are you using with this 24hrs set up? 100%?
