I have a Little Giant coolant pump that is rated 3A 110v. This is a centrifugal pump with a separate motor compartment and separate impeller compartment. This pump spent about a month in the back of my truck before I started looking at it. The motor compartment, which has a seal around its cover, was filled with fluid that looked like a mixture of oil with water.
My question is, are these compartments supposed to be empty, or filled with oil, for lubrication and motor cooling purposes?
I found that the pump runs (it had something minor out of order, such as loose setscrew that holds the impeller on the shaft), and I would like to try to run it for a couple of hours, but I am not sure what do I need to do with this motor compartment, is it supposed to be dry or not.
I have a use for this pump in mind, so it would be great if I could use it.
Thanks
