My question is: can you use this pump saver while the pump is filled with oil or while it is empty? Thank you in advance.

this clears the water from the water pump to keep it from freezing and splitting the pump. the oil in the engine can be full or empty -- makes no difference.

I used it while it was full of oil. That should not make a difference. The saver only flushes the water out of the pump.

While it is full. Give it a squirt every time after you use the pump especially when you store the pump for the winter

The oil in my pump is separate from the area where the water passes through, in other words, the oil is sealed away from the water. The pressure from the can pushes the anti-freeze liquid through the parts that carry water (which are, again, separate from the oil) and protects the pump from frozen water expansion. I wish I had this item prior to this year, as I had to replace the pump and I am certain it was due to incomplete removal of water from it during the winter. I just used it, and it was very easy to accomplish.

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

No oil. Mine doesn't require any oil to operate......just to store it in Winter....very important to Winterize the pump or freezing will damage it if water is left in the pump mechanism.

won't hurt, but most pumps come prelubed. just don't run it without water ever and oil.

No you cant leave it running 100% of the time its not meant for oil use. The Machine will give out if you leave it running for to long....Cycles are 5 min, 10 min, 20 min & 30 min cycles.

As a general rule, no pump likes to run dry. The water cools and may also help with lubrication. Sucking a little air might be OK but running dry is not, at least in my book, and that goes for any pump unless they expressly say it is. If you fix your leak, power on and and it pumps water without leaking around the shaft, you're probably OK.

We are pumping lapping oil with it and it doesn't seem to be phased at all by it. We however have it set up on a recirculating timer so it cycles on and off every few minutes. If this pump was run 12 hours a day, 5 days a week I couldn't see the pump lasting more than a month.

The pump has to be running to use it . Once the pump is off..it goes flat, but pumps back up in seconds when pump is on.

I think the problem with this unit is that when the pump is under full vacuum, the pressure that has built inside the unit you are sucking from, will pull the oil back down the line in the form of a vapor or fog. This is just my theory but this pump definitely has problems with the oil leaking, burning, coming back down the line, not good for making consumable products in my opinion.

Did you use just oil or have oil & spices? I've been using mine for months with no problem. I have to pump it pretty much every time I use it. Sorry yours doesn't work. I'd send it back.

I have done it both ways.....w/ oil and w/o......i think that it would be helpful if you are using in an area w/ lots of dust to help capture more of the particles, but, have found its not a issue since i change the filter and oil regularly.

It clearly states in the manual that it is not to be used with gasoline because there is not enough oil in gas to lubricate the pump. I only pumped diesel. I have no idea what would happen if I tried to pump gasoline.

Mine didn't come with one and this is the first I'm hearing about a filling funnel. I was wondering if there was an easier way to fill the oil canister. Good question I'm definitely going to research this.

Yes, it is a good idea to use it no matter where you store it. It is a lubricant for the pump.

After connecting pump saver to water inlet an injecting the pump saver until it exits the pump should be good enough, although I guess it wouldn't hurt to pull the cord a few times. Also the reviews on Amazon have some good suggestions.

I didn't try oil yet. But if I did I would suggest having the oil you want to dispose of at a higher level and pump consecutively and vigorously.

Try to warm the oil a little first. The cold, thick oil makes the pump very slow.
