Is this a self priming pump? If I lose elecricithy and then, will the pump pull water and keep cool or will run dry, overheat and burn out?

This pump is not self priming. Nor is it auto auto turn on/off. If you leave it running dry it'll run and burn out.

I don't think the pump turns off if the well goes dry. I don't have it near an open window and it's fine. I have other issues with mine and even sent it in to get it fixed and some of the features still don't work (can't set my timer for sleep mode). It's great if you just want a fan. I think it does chill up a small room really well. I cheat and fill up the well with 90% ice and just a little water. Good to clean out the fridge automatic ice maker.

First off, cool car! The pump works fine for continuous use. However, I would suggest wiring it with a relay and a toggle switch. When in heavy traffic or idleing for a long time the pump can overheat. Try to mount it in a place where it gets plenty of airflow. Also be careful starting it in extreme cold because the condensation can freeze and cause it to self destruct.

This is a quote from the manual: "DO NOT RUN THE PUMP DRY. The pump depends on water for cooling and lubrication. Operating the pump without water may cause the motor to overheat or cause damage to parts of the pump. It may also shorten the life of your pump."

There is no need to worry about weather or not you tap a line with or without a water sofener. The main concern is that you have suffecient flow to make the pump create a vaccum. The higher the flow the better. I think the minimun flow requirements is 5 gallons. It would be better to get it before the softener because it reduces to available flow to the device. Maybe you can increase to pressure on the system. I have a question for you, do you have a back up generator? It sounds like your on a well system.

itself suppose to be self priming-however I found if the head /suction is like 14 feet -it does need to be primed to help it along-if you don't hear the water flow through hoses within a 10 seconds stop and prime or you will burn out the impeller. I've found there is generally no problem when I transfer from 55 gallon barrels all the time. I don't know how large your burn piles are-but i don't believe this pump will give you the pressure your looking for. it works well but- sounds like you need a pump that i use in my camper-there're pricey but do the job 2gal a minute and 40 psi depending on the model. as far as fitting in to the barrel should be no problem just uses a standard garden hose-will fit through a 2 inch no problem. camper pump sounds like what you need-where you could put a garden spray nozzle on the end.

Yes. It recommends putting a little vegetable oil into the inlet ( I guess for initial lubrication) then submerge the end and start it up. Even if it looses prime during use, it will self prime and pick back up. This is an awesome little pump. Pumped alot of water from under my house in recent heavy rains

There is plastic inside and the friction creates heat. I think it relies on the liquid being pumped to cool it down and not melt the plastic. I would not use it to pump anything more then luke warm.I pumped more than 100 gal of heavy liquid 8' high in few hours and it's still working.

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

if your pump fails to start or gets clogged or runs to slow or..... If your salt chlorinator continues to run it could burn out.

You have to keep the intake clear of debris, like any pump, and keep the water level high enough, or it can burn out.

I have used mine for hrs at a time w/o rest pumping 100s of gallons from my pool. It has not gone off and on like you say so I don't know. I have pulled it out of water for a moment. It went off. Then it was immediately back on once it is back in the water.

the pump is not self priming. it is rated for out doors ,but build a shelter over it.

No, The pump motor gets hot if you uses it several times in a row. It would overheat after a few minutes.

Thanh,Yes, rhere will be damage. The pump has a plastic impeller that rotates and moves the water. If the pump runs for hours without moving water the plastic impeller will get very hot melt or bend and break. Also, there is a seal on the rotating shaft that will get very hot and be damaged. Sorry for the bad news but you must be very, very careful with the installation and make sure all connections do not leak.

I have 2 thoughts. 1) I just run my chlorine pump when my deep well pump runs and I don't see any problems. 2) The relay action you need is time delay on release (drop-out).

This pump primes itself when switched on ; then only runs if you trigger the sprayer wand. I've had no trouble with mine after spraying pesticides and weed killer.
