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.

Same issue here. I'm fairly sure that mine is overloaded (3/4 or 1 HP pump) and the Triac (electronic) switch inside gets too hot and fails to turn off. Unplugging it for a while to cool down makes it work again for a while. At low duty cycle (off a lot more than on) it works OK. I can't find one that works as well that is rated for lager pumps.

I don't remember it being hot. I would only worry if it was hot by the motor or plug. I have 2, been using for years without a problem.

I had this pump at the top of my waterfall. That point down the bottom of my pond is 7' 8". Huge volumes of air came out of this pump. I had four 1/4" hoses coming out of the pump and some of the runs on the bottom of the pond were in excess of 14 feet from the pump outlet. This pump is rated at maximum of 100 F. I live in AZ and the temperature can reach near 120. Even before it broke 100, the plastic air distribution unit melted. The motor runs very hot. It would cut out during the warmest part of the day. It finally just quit working during a stretch of 115 F days. It was always operated in the shade. I had this pump at the top of my waterfall. That point down the bottom of my pond is 7' 8".

Mine also runs quite hot. After a year of "continuous running" it still runs hot and has not failed.

I just overheated mine the other day, pumping 4 tires from nearly 0 pressure. Let it sit for a few hours, while I did other things, came back and finished the last tire.

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!

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!

I have ran my pump for 6 to 8 hours at a time with no heat problems! I did however upgrade the power cord to a 12 ga. wire.

it sounds like the water is puming out to fast for the water coming in. the pump is probably too big for your application. try reducing the outlet hose size to about 3/4" instead of the 1 1/4" it is set up for. if the float had about 8" of travel instead of 3" you would be fine. my pump works fine for me, i am happy with it.

I hate to be the bearer of bad news, I was very unhappy with that pump. I warmed up my boat engine for about 15 minutes and let that pump run for about 20 minutes and bearly got a quart out. Used a hand pump and got the rest out in about 5 minutes

If you feel uncomfortable with the units power transformer, then you should return it or just get a new one. I have measured my transformer heat output and at in house temptress of 75°F, it is around 95°F They are designed to get hot and have vent slots to allow cooling, unit is reducing your household current from 120VAC/60Hz/10VA down to 12VAC/6VA. That in itself causes the unit to get hot. A bad pump will also cause unit to over heat. My unit has worked fine for over a year, but I clean it monthly including build up that tends to clog pump.

Not normal! No motor noise, maybe just a hum. Unless the motor is not stationed firmly and is maybe vibrating, I would return. Mine is so quiet, I sometimes forget it is there until I here running water!

If it only did it the first time you ran it. It is normal. Burning off oil on metal from manufacture.

Carol it runs better with real good 12 volt voltage. I ran off of the twelve volt motor that lifts the trailer up and down. I ran it to a standard 120 plug. It looks like it is 120 but it is only 12 volts from the pump I pot a regular cord that plugs in. I marked it so I plug it in the same way each time. I think the pump will run back wards if you reverse the power. That should give you a good start. Have fun and your welcome

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
