How does this product work with variable speed pumps. I run mine at low speeds for 24 hours a day. Will I still get good circulation?

I honestly can't give you the answer you are looking for. Better to use the contact info on the web site.

I own a variable speed pump, the circulator barely works at low speeds. The 1st one I purchased didn't work, the 2nd one worked for about 5 months and it has stopped. I contacted the company months ago and NO RESPONSE! Don't purchase it.

Based on my experience with these devices, running on variable speed should only change the flow rate in GPH. I run a 3/4hp pump on mine 8 hours a day in the off season and 12 hours a day in the summer. I can say that these devices make your pool more efficient in regards to how much turnover the pool has with the water. Hope this helps.

It does not have a speed control. You would mount a ball valve on the output side of the pump and control the flow with the valve.

Sometimes mine can take up to a few minutes but rarely longer. Is the pump mechanism installed correctly? Is the water level high enough? (Sorry to ask dumb troubleshooting Qs)

I use this pump to drain ponds and do water changes. I have never run it continuously except if a pumpgoes out in by ponds. I just use it to keep water moving until I can put in a new submersible pump. It isa powerful pump though. May ask the manufacturer if it can be used on a continuous basis..

I've got about a 350 gpH pump and I have to dial it down. I have 90 total system gallons. I'm tumbling npx balls in it and they like a nice slow tumble.

I have one that I installed myself a month ago and so far I haven't had any problems. I'm most pleased with the circulation pump. No waiting for hot water.

It should pump .. period. It is hooked up wrong(No Offense)or it is defective. My advice? Just send it back .. FWIWFinal, I was unempressed with mine .. Just got rid of it in part .... because I took to long to qualify for a refund.

Sorry, can't help you with this. The simple solution may be to just not pump as much.

yes, It is working fine for me. tun the power off before connecting. suitable for small pumps for house circulating pumps. I hope this helped.

Big savings come if you can run the pump around 2100 RPM where it will be drawing approx 2-2.5 amps. My 16 X 32 pool is kept clear with pump running at 1940 RPM 24 Hrs a day. (410 Watts or 1.8 amps at 230 Approx). Your situation will be different but any setting that will allow you to run the pump at less than full speed might result in savings over a single speed motor.

I use this on a 20 gallon tank. It does not seem to have a very strong flow for its size I would not recommend using this in a small tank such as yours. The unit itself would be too large for your tank and too strong. If you have a good filter pump for your tank I would think that it would be sufficient for circulation.

Carl G I would like to know why you needed an oil lubricated pump? Changing to wet rotor may be an issue because of the clearances...if it stops it might only a small particle...I once had some system "goo" hat stopped one...it took washing it out with diesel to get it back running. Both engineering submitals indicate the NRF22 is about 2GPM less than the LR20BF at 10ft head...so here's the thing...depending on what system youre installing it on...most systems were designed for 160f DHW or 180f HWH water so by putting this in (I dont know your system but I would do it) you'll have a slighting lower flow rate...in DHW who cares as its no big deal...BUT in a HWH system your control valves will open more and this is a seriously good thing in modulating valves. There will be a larger delta T so I'd also lower my boiler temperature by at least 20f assuming youve some form of condensing boiler...this will help ensure youre in condensing mode. Circulate fluid...not temperature and you'll save a lot of money. Make sure your side stream filter is clean and check it a few times in the first 1-2 months because the more flow means the more crud is likely to get back to your HEX...if there isnt one put a Y strainer in and add a "sock" on the screen for a month or 2). A possible problem is how many zones open/ resistance decreases across too many different circuits/ zones...too many and there wont be enough. The system I installed this on it is actually the primary circulator through a 2xwall HEX serving the HWH off the DHW system...it works so well Ive been promoting it/ its been installed on 3 systems in this last year (its not my J.O.B but I do design energy and conservation projects as is my profession). Last, make sure the expansion tank is on the pump inlet side/ the return (DHWR or HWHR)...these high speed pumps cannot handle even a minimal bit of cavitation. All the best

That is a hard one to answer. I had one that only lasted a few months but general I would say they last two to three years. Some definitely work better than others. I would think that the hours that you run the pump daily would be a factor. Good luck.

Hello J. Taneri, I've never really pumped any distance with mine the only info I could give you is what I have done with mine-I've pumped from a stream- with the pump drawing the water from about 8 feet down to a barrel in my Jeep and the discharge hose is app 12 feet long. It took awhile to fill the 55 gallons maybe about 3 gal per minute. Maybe I was over exerting the pump the way I was using it??? I failed to prime the pump one time i got too impatient and burned the impeller. I got a replacement and it works fine again. any other questions please ask. jerry mayers Hello J.

Hi... i used a regular pump like the one you use for bicycles. Just be mindful of the air pressure limits.Enjoy!

I am actually using mine for the same purpose, but I do have a second pump for my chiller which provides additional flow, as well as two power heads to mix up the currents. It is recommended with pump size ito turn over the total volume of water 10-15 times per hour.

No, it would not do that. It can smooth out pressure pulses over very short periods of time. 10-20 seconds typically. Most gravity fed systems don't have enough pressure to make an accumulator work well. This should be used on pump systems of 40-60 psi.
