New pump and motor consideration. What do you think?

[Charlie227]

I have and old, leaking, tired, what looks like a Home Depot pump and motor. It’s 13 years old and ready for replacement. I am considering the single speed 1.5 hp Pentair SuperMax (Sta-Rite). I am not considering a VS unit due to cost. What do you think? Good choice? Thanks.

How long do you run your pump daily? What is your electrical cost per kwh?

Look at PureLine Pool Pumps - INYOPools.com and see if a VS pump fits your budget.

You should look into a VS pump anyway- the energy savings will pay for it in short order. Also check with your electric company as many are offering rebates.

Pump runs 10.5 hours a day. Kwh cost is 12 cents per. This is a Florida pool and the pump runs 12 months a year.

I’ll check it out. Thank you.

A VS pump running at low speeds can save you $30-$40/month. $360-$480/year.

How about a two speed?

Its a shame you are so far away. I’m taking a pump and motor to the dumps next trip.

Ok, you folks have me thinking about a VS Pump now. A couple of questions. I have a salt pool.

Does the reduced, longer flow make any difference to a SWG? It seems as though I could turn my SWG down to a lower % if the pump is running longer?

At a lower rpm setting on the VS, am I getting reduced water pressure to the filter?

Are the return jets pushing water back to the pool at a reduced rate?

If the turnover rate is alot less, how long do I need to run a VS pump for my size 12000 pool?

Thanks for your comments.

AS long as your rpms give enough flow for your SWG flow switch you are good. Typically that is around 1500 rpm.

Yes, you can run your pump longer, at less cost, and lower your SWG % to get the same daily FC output.

At a lower rpm setting on the VS, am I getting reduced water pressure to the filter?

Yes, and the filter works fine at lower flow rates.

Are the return jets pushing water back to the pool at a reduced rate?

Yes.

If the turnover rate is alot less, how long do I need to run a VS pump for my size 12000 pool?

Turnovers are a myth and meaningless.

Determine Pump Run Time

To figure out how many hours you need to run your pump, you need to know how fast your pump works. You can find this here.

Thanks Allen. Great advice.

I went with the Pentair SuperMax VS. It was installed this morning and is working great. Thanks for the good info here.
