Sump pump

[Earl Grey]

A friend was checking out a submersible sump pump, and found there was oil in it, and he dumped it out. I think the oil is in them to dissipate the heat from the windings to the case, to keep them cool. Anyone have any knowledge on this, what kind of oil and how much? Thanks!

Quite likely coolant. The oil would be as recommended by the manufacturer. Guessing would be unlikely to work well. Seek info from the maker. I do believe in submersible pumps, and they are compact.
With pump operation as frequent as described, I would consider putting effort into repairing the foundation to make the structure more usable and less dependent on electricity to prevent flooding. Jim

Our house was built in 1995. We moved bought it in 2014. It sits on top of a gravel hill. It has footing tile which dumped into a sump with a sump pump. One of the first things I did, after moving in, was to add a tile, outdoors letting gravity to drain the water away, even if we lost electric power.

That’s nice!

Dielectric oil should be used in it. Not only is it used as a coolant. It also serves as an insulator.

How much.. I will have to say it needs filled to the full mark or enough to fully cover the windings since no one has a clue when it comes to the make and model.

Yes, that is a dielectric oil. Keep it in there. Dissipates head as well a lube.

"Drain to daylight"... good for both water and radon. Sump pumps don't pump radon very well.

Hide all of your buddy’s tools and enroll him in knitting classes instead .

And tell him he can pick up a 55 gallon drum of dielectric oil for a couple grand. Change the oil every 3,000 gallons pumped, every 3 months, or every 3,000 miles, whichever comes first.
