My water pump keeps getting quite hot after each use. Everything seems to be working properly, except I think that the heat may cause it to burn out and that would cause a huge problem. My pump pulls water from a ground level water tank and pushes water up three flats to the part of my house used for living quarters. The pressure setting is set to cut out at 40psi and cut in at 25psi. What can I do myself before calling in expensive experts?
Probably needs new motor brushes.
might be bearings in the motor or could need a good cleaning and reapcking with heavy lithium grease or maybe get some kind of colloing fan or raditor system to keep it cool !
You have an air volume problem and the tank is water logged. When this happens the pump motor short cycles and creates more heat than it can dissipate. A device inside the motor windings cuts the power until it cools again. You can cut the power off,drain the tank, then start all over, it will give you1/3 air pressure volume over 2/3 water. They have an air volume control that may not be operating properly. I use an air compressor on my pump and pump air into the tank about once every two months. It all depends on how much the pump runs.
You need to be more clear.. is it the pump thats getting hot or is the motor that drives the pump. If its the motor, well that may be normal cause motors are made to work. depending on how old the motor is the windings in it may be losing their insulation. the more insulation is lost the hotter it will get and eventually come to the end of its life. If its the pump only getting hot then it could be that something got inside it and is causing it to run hot. Usually its some debris that got inside of it. If you can, open it up and inspect it. There are many types of pumps so which one you have i can not say but this should lead you to the source of the problem. Was there ever a time when the pump ran cooler or is this something you just discovered? It may be normal for it to run hot. Motors are workhorses and they just work.
