Yes.

I'm a little baffled. I noticed the K2 1hp uses 3.2 amps.

Where did you see that?

So if I get the K2 1hp and run it at 1400 rpm, it would be more efficient than the Xtremepower 1.5 hp 9.5 amp running at 800 rpm achieving similar flow rate? I used this calculation, K2 3.2x1200=4480, Xtreme 9.5x800=7600. I thought the bigger pump would be more energy efficient at lower rpm?

At 800 RPM the Xtreme is not going to pull 9.5 amps.

I don't know what data you are looking at.

Under specifications in here. Says 3.2 amp

K2 1 HP Variable Speed Pool Pump PPV10001SPK - The Home Depot

The K2 1 HP Variable Speed Pool Pump is self-priming and suitable for inground swimming pools. The DOE and CEC compliant 230-Volt motor operates at low, medium and high speeds. The permanent magnet, totally

So to clarify, when they say 3.2, 5.0 or 9.5 amps, precisely what does it mean?

The amperage rating on the motor data plate is for maximum RPM.

I don't know what 3.2A means since they don;t specify what voltage the pump is - 120V or 240V?

The specs say the K2 will flow 65GPM with a 10ft head. If that is the maximum performance it is very low.

It can do 65GPM with 25 ft head at 2400 RPMs.

Inground pools have more then 10ft of head for the pump to overcome.

This is the specs on the K2

The K2 has a 230-Volt permanent magnet, totally enclosed fan cooled (TEFC) motor. Is that good?

I see the Xtreme VSP has the 1.5 HP motor that runs on single phase 230-Vot 60 Hz current. Isn't that an old style motor?

Also the Xtreme has a discharge flow of 92 gpm at 10 feet. Is that sufficient?

I did a little measuring. My pump is 8 feet from the pool and skimmer, 13 feet from the 1 main drain and about 23 feet from the 2 return jets.

That is like caring if it takes a 4 cylinder engine or an 8 cylinder engine to do 80MPH on the highway?

I don't care and you should not either.

Sufficient for what?

The Hayward pump above can do 140GPM with a 10ft head.

Distance is not what feet of head is about.

Yikes. I can't have a 140 gpm pump. Remember, I have the older 1 1/4" pipes. It'll put a strain on them.

In the old days, a 1 hp single speed pump is all I needed. Nowadays, the VSP has confused me a bit hence why I'm being inquisitive before I buy one.

So bottomline, forget about the 1hp VSP regardless and get a 1.5 hp VSP, as it'll be more efficient and fine for my 1 1/4" pipes?

Sure you can. Just because your car and speedometer can go up to 120MPH does not mean you operate your car at that speed.

Back to the original discussion. When you run that 140gpm pump at an RPM to give you the 30-50 GPM your pool needs it will be running slow and using litlle electricity.

The cheap pumps do not supply the pump curve data to evaluate pump performance.

This is what I found in the manual. Does this help?

Comparing those performance curves tells me that pump is lower performance and will use more energy then the Hayward I posted above.

I feel silly asking this. Some of you have posted the curve charts. How do one compare the charts? What do we look for?

Look at the head on the left. The higher numbers are better. The ones you posted are 10-20 max. The ones we are posting are into the 80s.
 
I'm new here, but since it was mentioned I thought y'all should know that as of Monday morning, the Calimar 3hp was backordered with 8-12 weeks estimated arrival, but then Poolsupplyunlimited actually received a shipment of them on Monday and they're still in stock as of right now, so get one while you can. I had ordered one Sunday but cancelled it once I found out the lead time. They actually called me Monday to tell me they had come in.

Hi again. I pulled the trigger and bought both pump, the K2 1hp VSP and Xtremepower 1.5hp VSP with a 3 year extended warranty.

I have 90 days to return them to Home Depot so I'm going to do a little experiment. I'd like to share with you all.

Before I pulled out my old 1 hp single speed pump, I turned all the power off and the house meter is pulling 1.076 kw which is about right.

I have the K2 1hp hooked up now. It's pulling 0.95 kw at 3500 rpm and got 9" of vacuum at the navigator head with 10 psi on the cleaned cartridge filter. I needed to make sure I'd have enough vacuum to run the cleaner.

At 3300 rpm, 0.87 kw, 7.5" vacuum and 8 psi.
At 3000 rpm, .82 kw, 7" and 5 psi.
2500 rpm, .57 kw, 4.5" and 2 psi.
1400 rpm, .38 kw, 0" and of course 0 psi at this low speed. Pretty quiet here.
1200 rpm, .36 kw, 0" and 0 psi
1000 rpm, .34 kw

Are these good numbers?

Keep in mind, I have 1 1/4" pipes with 2" dedicated vacuum line.

I don't know how many GPM it's flowing as I don't have a flow meter.

What other data should I check before swapping this out to the Xtremepower 1.5 hp pump?

Thanks all
