Thanks Dennis, have you heard of such a product please ? I was told by regulating the running speed, it saves cost, which of course makes sense to me ,
but i am not sure what aspects i should consider when choosing a right one,hence my question....

I don't know of such a product but there are variable speed pumps on the market which do reduce your electricity cost substantially
I was told there was no way to slow a swimming pool pump motor electronically otherwise I would have bought one. I suggest that you investigate whether your pump is capable of being slowed down before you go ahead

That's very kind of you Dennis, thank you for your suggestion, a variable speed pump is kinda expensive for the moment, so we are considering installing a pump speed controller to go along with existing single speed pump, i was told by sales reps this could enable a pump run at set time and speed.

Hi Hsiao
Check by them that it is suitable for your pump and if you do go ahead please post back so that others may benefit from your experience. I got a smaller pump because I didn't think it was possible
Thanks

Hi, Newbie on this site but joined to answer this question. Yes you can control the motor speed of a single phase pump.
It will save you money but there are other things to take into consideration. If you slow the pump too much you won't filter that much water and skimmers don't function that well so I suggest care and a flow meter.
You don't say much about the size of your filter or pump, suggest you add those details and then we can take a look before you spend your money.

You are quiet correct that you won't filter so much water and skimming would be reduced
There is no pre determined about of water that should be turned over and pump run time and speed would be to
Mix chemicals
Clean and skim
Run SWCG
You would have to run it at various speeds for the correct operation

Hi Dennis & Teapot,
I am so glad i sought help from professionals, thank you soooo much for your advices, as I honestly haven't got much idea about technical things of a pool system,
it's a 1.5hp single phase pump we have, Qmax 350 l/min, Hmax 14, the pump speed controller as i was told enables a change from 1200 rpm to 2900 rpm and 4 timers available which allows you to set different time period so that your pool can run at different speed respectively within the time frame...
Best regards,
Hsiao C.

What is the size of your pool (gallons/Llitres)
The controller sounds excellent being able to time at different speeds
I went from a 1hp to a .5hp because my pump was pushing to much water through my sand filter to filter properly
My pool is 10k UK gallons 45000 litres
