What setting should I use to avoid stripping gears and causing wear? I have a Variable speed pump 1.5hp, should i use 3000, 2500, 1500 rpm?

Theres a yellow marker on one of the wheels that you watch and count off 10 revolutions. 10 - 19 seconds is too fast and damage will occur. 26 to 50 seconds is too slow and you will have poor performance. The ideal number of seconds for 10 revolutions is between 20 - 25 seconds. Set your flow accordingly.

10... When set at the lowest RPM8... When set at the highest RPMThis is quite an excellent pump. When you are not swimming in the pool, it is quite sufficient to leve the pump running at a low RP!

i have done a lot of research on bilge pumps.the #1 insurance claim for sinking is pump failure.if i had only ONE pump say 6 or 7 amps,i would use #14 min with a higher rated fuse than the pump

Previously, I had a Hayward single speed pump (3000 rpm). Now, with my Hayward SP2300 VSP, my energy consumption is reduced by approx. 55 to 75% (running at 2200 to 1500 rpm). This means that my new pump will pay for itself within approximately 12 months of continuous usage! If you plan to use your pool in the next few years, it is worth it to replace it now. You may want to calculate the energy savings using your local electricity rate to see how long it takes for the pump to pay for itself. When you do this calculation, you will wonder why you didn't replace the pump sooner!

I believe that there is a 2 HP pump that will work for you just fine, but a single speed will never compare to a variable speed pump. A lower hp will only put more work on the pump since you would probably have to run it longer to have proper filtration of a pool that size. I certainly would NOT go with a lower HP but I would go to variable. Additionally, even if the other Pentair pump at a lower HP had 2" fittings you can come out of the pump with 2" and reduce to 1.5 as I had to do in order to tie into my existing system.

Yes and No! When you first turn on the pump, it thinks for a while, then goes to its Prime speed. After a time it switches to V2, its second speed, and runs at that speed for a long time, before switching to V3. You can set the amount of time it runs at V2, as well as the speeds it runs at for the various speeds.If your power goes off, it starts back at Prime (3000 RPM) and repeats the cycle. Most people like a timer to shut the motor off at a chosen time, and restart it the next day, or whenever. So, I recommend you have a timer, but it is not essential.

I recommend a low RPM motor that has a 5/8 shaft with keyway. You can get 5/8 bore pulleys at a hardware store. You may have to order the pulley that goes on your mill since I could not find that size at the store. My system is configured with a 5" pulley on the motor and a 3" pulley at the mill with a 30" belt to get an RPM from 83 to 133. Your motor doesn't necessarily have to be that low of RPM but you do want to crush your mill any higher than 200RPM. I spoke to Todd Millar, the inventor of this product and he recommends no more than 200. Wether you have to reduce or increase your speed, go to this site to figure out what pulley size you need to achieve your desired RPM: blocklayer.com/pulley-belteng.aspx

It is a variable speed, it works flawless, right now i am using 93% less energy. It depends of the size of your pool, mine is a 26,000 Gallons, the maximum amount of water that can go trough my 1.5" plumbing is near 42 GPM and i do it in a 1300 RPM basis on that pump, and it is using only 170 Watts per hour. Regards!

It's not expensive for a 1 1/2 hp pump that is 110/ 240 v when I shopped around I found the MSRP was false and varied end user prices were much closer. Watch for shipping fees pump is heavy. Use ground if possible

Even if the bolt pattern and the shaft are the same size allowing the pump to physically connect to the engine, you will probably not have enough power to run the pump. I made a similar mistake by putting a 3000psi pump on my engine which came with a 2400psi pump and the engine was heavily strained. Stick with the correct psi pump that came with the pressure washer for best results.

There are two speed settings. When set on 2, the higher rpm setting,it's rated at 1400 rpm.

Variable speed from 5,000 - 20,000rpm (no load)Hope this helps ! Best wishes.

No, I would not. The gears use grease seals, and the grease comes out into the stream over time which is why vacuum diminishes. When you first start using these pumps, you can sometimes see a sheen on the surface of water that has been pumped. Yuck.

It does not matter here. The gears will strip long before the motor will fail which nearly caused a potential disaster in my jack.

I've heard that 2-3 continuous horsepower is needed especially if you're going to be using the treadmill for extended period of time at low (walking speeds). It is actually more taxing on the motor when you are going slowly, unless you are walking at an incline.

There is a speed switch on the Grundfos that I bought. I think it is 3 speeds, but I only use the full speed setting. If I were trying to rig up a thermostat to the pump, I suppose I would look online at Omega. It would be a pretty simple matter to rig up a relay to a therm switch to turn the pump on and off. Good luck

I use a 1.5 HP pump. I am not certain of a min. pump spec, but feel certain that 1HP would be sufficient, also.
