Can I make my wfe-6 a 2 speed pump?

The WFE-6 comes with a 073129 impeller.

Impeller......Total HP.
073126.........0.95
073127.........1.25
073128.........1.65
073129.........2.20
073130.........2.60
073131.........3.45

The total hp is the rated hp x the service factor.

The new motor would need to be at least 2.2 total hp.

I would suggest a variable speed motor.

If your pump is old or in poor condition, you should replace the whole pump.

I am adding a circipool swg, and I have to replace the pool pump. (previous post Can I make my wfe-6 a 2 speed pump?). In researching recommendations I ran across the circupool combo deal (Part Number: COMBOC-CORE55-SF1.5P). The price looks appealing at $2112. What are these pumps like? Are they reliable? Are they a well made product? Are there any benefits to staying in the circupool family of products. (I may go with the rj line of swg and I still have to nail down the right size pump, this is just an example of the combo deals offered). Thanks for the help.

Any SWG can work with any pump. No special reason the SWG and pump should be from the same vendor unless you intend to connect it to that vendors automation.

I have not seen much mention of the pumps. I think they are fairly new product. Probably manufactured in Asia like most pool equipment is and have the Circupool brand put on them.
 
I am adding the circupool rj 60 swg and I need a new pump. I guess it comes down to intelliflo vs tri star. The pool is 18x36, holds about 27000 gallons, (new liner going in next month), 1 1/2 piping, and a rheem 33000btu nat gas heater. I have always had a 1 speed pump (1.5 hp whisperflo) paired to a simple clock timer. I need to find out what hp pump I will need, what flow rates will I need to activate the heater and swg. What are the chances the new pump will drop in and mate with my existing pipe setup? Will the heater kick up the pump to meet the demand when heating is called for? Could you recommend any other equipment that I might want to add at this time. Thank you.

The Intelliflo VS should be a drop in depending on if you have pump unions.
You also will need 240V electrical service.

Automation will run the pump at a higher flow rate if heat is called for. With the Intelliflo pump, you would need a Pentair automation.
The Circupool SWCG cannot be controlled by automation. It can be set up to be powered off when the pump is not running, which is important, by using a relay in the automation system. But you will not be able to adjust the % generation via the automation.

Sorry bout that.
I have the 240 volt .
I saw the new style unions on the tube and will look into it. But after reading the specs for the pump I don't think I have enough pipe between the pump intake and the diverter valve. I have the room to slide the filter over a few inches but I will have to re-pipe it from the filter to the heater.
I suppose its best to go with the higher horsepower pump, it's only a few dollars more.
Thanks again.

The suction side distance is not all that set in stone. Only really comes into play if you must run the pump at high rpm , say for a spa or water feature.

It is. But it’s not always that simple. A higher HP VS pump can run slower speeds to move the same volume making it a long term energy savings. That does not help the person paying for it now.

I recommend stalking the online sales and jumping if you see something good. (*if* it’s available, ****if****. It’s actually available and not just normally available directly from the manufacturer. 2 of my 3 recent purchases got kicked back immediately after purchase with being backordered).

Yesterday I had an electrician out for a build quote and he commented that he loved the intelloflo. He asked if it cost me $1300 and I told him that it went up to $1500 and I was GLAD to pay it a few weeks back. Afterwards I looked it up and Amazon had it for $1850. Yikes.
 
The Hayward tristar vs W3SP3206VSP is my final answer, unless there's something you know that I don't. (really, let me know.) I was planning on installing it myself, until reading through the rebate requirements at pseg. They require an approved installer do the honors. That takes half of the rebate, but not nearly as expensive as my first 5 wives :) I would like to thank everyone who offered advise and information. I couldn't do it without you.

Thanks to all the members of tfp who helped me through. I installed a new liner, a sta rite vfp pump and a rj-60 swg. I have been up and running for about 2 or 3 weeks now and all is well.
I went with the company who originally installed my pool 30 years ago and they did a good job. I paid a little more but they did the job right and I qualified for the $425 rebates from pentair and my local power company.
I have a couple of questions- I have the pump set to run at 2700 rpm for 4 hours, then 1700 for 20 hours. Seems to be ok so far, is that a reasonable schedule? I do like the slow flow in the pool on the low speed, and I read a post that said don't worry about turning over the water so many times a day like they used to say.
Is my heater less efficient with the lower volume of water running through it?
Thanks again.
 
Rheem natural gas heater 336k btu (new 2015).

The heater needs a minimum of 35 gpm.

Anything less will cause the heater to overheat.

Anything more won't make any significant difference in efficiency.

I would target about 40 gpm when the heater is on or about 15 to 20 gpm when the heater is off.
 
Is this your new pump?

If yes, can you go to the control panel and find the flow at the following speeds (1,500 rpm, 2,350 rpm, 3,110 rpm and 3,450 rpm)?

Don't go to full speed if you think that it will create too much pressure for your system.

From the keypad, you can get the total system psi and gpm as shown in the below video.

X = water temperature going into the heater from the heater water temperature display.

Y = Water temperature coming out of heater from the SWG temperature reading

Z = Temperature rise = Y – X = Z

Run the pump at the following speeds and record the following information.

RPM........Filter PSI....Pump PSI.....Pump GPM......X.........Y...........Z

1,500......_________...._________.......__________........_____..._____..._____

1,725......_________...._________.......__________........_____..._____..._____

1,925......_________...._________.......__________........_____..._____..._____

2,350......_________...._________.......__________........_____..._____..._____

2,730......_________...._________.......__________........_____..._____..._____

3,110......_________...._________.......__________........_____..._____..._____

3,450......_________...._________.......__________........_____..._____..._____


Once you get the information, you can plot the gpm on the pump performance curves to get the system curve.

Below is an example of two system curves. The steep left curve is a poorly designed system and the one on the right is a well designed system.

Most system curves will hit the 3,450 rpm curve between the two arrows.
