Want to upgrade pump to save $

[GaryT]

I CAN source the Pentaire SF-N1-3/4FE It appears to be the single speed version of the one you recommended Mark.
1 1/2 in plumbing & high efficiency, but not 2 speed. Could I run it for 8 hours per day and get most of the benefits?
Would this be your "second" choice for me?

I don't have answers, but I do have a question: can US suppliers not ship equipment across the border?

(I knew about problems with chemicals and testkits, but I hadn't considered gear.)

[GaryT]

Some will. Brokerage fees can kill. Often 20% extra.
Sometimes I drive across boarder for bigger items.

If you can't find someone to ship to Canada, then my second choice would be the 1 HP version SF-N2-1A (340042) which should be similar to your current pump. If that worked fine for you, then the 1 HP should be fine as well although it is probably a little bigger than required.

But this place has the 3/4 HP I just don't know if they ship over the boarder but I think most online places will:

Also, the Sta-Rite SuperMax is exactly the same pump (PHK2RAY6D-101L):

This company looks like it ships worldwide:

Here is the 1 HP version:

One additional consideration is the line voltage. The 3/4 HP is 115v and the 1 HP is 230v so that may override any other consideration if it would be difficult to change.

Mark, I just installed the Whisperflo 1/2hp WFE-2 because it was the only reasonable choice I could get in time to replace the 1 hp Sta Rite I sold.
As it was I was pumpless" for 48 hours.

The Whisperflo seems to run a lot cooler and pump about the same volume. Pressure dropped to 15.5 from 17 psi.
Since the SF on the 1HP Sta Rite was 1.25 would you have any idea how much I might save with the new WhisperFlow running 8 h per day.
Cost of electricity is $0.20/kwh

Thanks for your help, Gary

ps. I am in the habit of backwashing into a 55 gal drum. The old pump took 62 seconds to fill it. I will be able to compare pump volume easily when I back wash with the new pump.
BTW I gravity feed the back wash water back into the pool after it settles and clears. Essentially I use only a gal to back wash my pool

Interesting. I'll have to try that sometime.

Depends on your plumbing and which pump you got (WF vs WFE) but as a rough estimate, your old pump probably used around 1400 watts while your new pump uses around 1300 watts. So you are probably saving 100 watts per hour of operation or $0.02/hour.

Sounds more or less like a homemade separation tank.

It is the HALF HP WFE-2 Mark.
Would it really use the same KWs asatheist 1 HP.
Thanks.

The WFE-2 is a little better at 1200 watts. The Whisperflo series are very large pumps. The WFE-2 has the same power/flow of some full rated 3/4 HP and 1 HP uprated pumps which is what you had. Downsizing a pump based solely on label HP alone may not always give you better energy performance. This is the primary reason I suggested going with a two speed pump in the Superflo series.

[GaryT]

Thanks Mark. I prefer the 2 speed you recommended also.
Horner said they would ship to Canada. I could order it, install it and THEN sell this Whisperflow if you think the savings would be worthwhile.
If you have time could you compare the cost of running this WFE-2 to the Superflow 2 speed.
BTW, this 1/2hp Whisperflow took 64 sec to fill the 55gal drum on backwash, The StaRite did it in 62 sec.
