I just installed this pump. After letting it run for about 10 minutes I noticed that the exterior of the pump motor is very hot. Is this normal?

It seems to run very hot, I could almost fry an egg on it! Btw- it's nit supposed to be exposed to direct rain.

Yes this is normal. It will be hot to the touch but I don't think it will cause blistering. When you install it the pump to the filter, make sure you breathing room at the bottom vent.

It can get pretty hot. As long as it is not making a lot of noise (bearing) and it is pumping water, it should be fine. I would just keep an eye on it for a while.

No, it isn't normal. Mine will do that for a couple of pumps until it is primed after being empty. After that, it is a pure stream of water with the range depending on how fast you pump it. On a fast pump, it will go 20 feet or more.

Mine is quite new. I don't have a flow issue at all. I do know that the style of an old farm pump dictates a lower than normal flow. As it is not aerated, the pure water flow if faster would be quite messy. I have read on other review sites that had a similar complaint and the solution was to remove or punch a hole through the screen at the flex hose inlet on the hot side will help the hot side. It was felt that the screen holes were restricting under expansion from the heat. Please note that by opening the screen, you are allowing any potential solids that could be lurking in your pipes to enter the valve and cause leaks and/or damage. To sum it up. I happen to like the lower flow as it does look like a cool old pump. Good luck, Al

I asked the same question to manufacturer; they said yes it was normal. Sometimes my fan would not even start until there was enough heat generated for it kick in. I can only surmise that the machine is smarter than me!

Hi Paul H,Is there any update ? Have you talked to your technician ? It's almost a week and that pump is still not doing anything, I really want it to work.Thank you.

Mine has not been hot. It if did get hot would depend on how long you had it on, what you were inflating, and the PSI needed.If you are going to inflate a tractor tire it may take a while.

it should not get very hot or smell hot , make sure it matches old motors specs ie. amp draw ,horsepower, & correct voltage & rotation

I've not actually experienced this. You might have a defective pump, although I can't be certain.

Mine ran "hard" for the first few hrs--maybe the 1st day?? But it was hot-summertime. If I change the temp/open the door it ramps up for a few min but otherwise very quiet. I'd say you might have a little issue. (You may want to check the venting space, make sure it has enough space behind/around to vent. I only say this cuz I helped kill another cooler w/ a lack of vent space.) Good luck w/ it!

Mine gets very warm/hot, but I can still touch it. I only run my vac for about 10 min at a time.

Mine was quite noisy and I thought it had a bad bearing. Technical support told me to check the end of the pump that was perforated since it can be bumped and become cocked and lets the fan hit the housing. He told me to remove it to see if it helped. I could see that it wasn't sitting properly and moved it and it ran with just a hum of the motor turning. Was quite happy.

++the blue dot red dot on the plug makes it hot running or cool runingg. It in the manual to show you which way for plug service.. good luck..hope i could help..

I believe this pump has a thermo disconnect. If it runs dry and over heats it will shut off. My problem with them was that a winding probably shorted out and the pump would over heat and shut down. When the pump cooled off it would start again. There was also oil in the pond so the cooling oil probably leaked out some also. The thermo disconnect is like an emergency brake on a car. It shouldn't be use as a normal mode of operation. I used this Little Giant model for a lot of years in my pond. I no longer use them because they do not hold up to continuous use now. They probably work okay for sump pump use but I would not let it run dry if I could help it. Hope this helps. I believe this pump has a thermo disconnect.

My best guess is that the pump circuit is very dry and it needs to be primed with an EXTERNAL hand pump. They are avaiable for a small sum.

I'm not an expert, but it sounds like something is preventing the motor from running. It could be an obstruction in the impeller, or the motor might have rusted in position--especially if it hasn't been run for a while. If you can, you should remove the pump and take it to any shop that repairs electric motors. Even if they have to rebuild it, it would probably cost less than a new pump. Good luck!

I would like to give you some input but just brought it out to the shop to test. i had purchased other pumps that claim to be high temp but failed within hours and in cold water. My desirefor this pump is to circulate water or coolent exchange for winter water heating and space heating. Looking at this pump with x-ray eyes has determined that the configuration is much like oil pumps in the industry. First seen it on the old VW's. Looks reliable so long as the motor is bearinged and not bushinged. Mark

This could be a problem with the on/off switch on the handle or the main motor. If you have the main switch on and water is spraying out the bottom from either pump (there are separate wash and rinse electric water pumps) then there's a problem with the motor. If not then it could be anywhere between the electrical outlet and the motor (plug, cord, switch or internal wiring)
