Rated 5 out of 5 by This pump was used in our pet washing machine that we use in our grooming shop. It ran trouble free for 10 years 5 days a week, The only problem was the auto switch went bad after about 10 years. I bought a replacement motor for the washer system, then changed out the switch in the original and kept for a back up .Now after another ten years I had to replaced the switch again, but instead of using my back up, I replaced the switch and re installed it and all is well, I believe the pump can run 20 years but the switch will fail after 10.

They are not the same and I am unsure why our search engine is brings up item #4UN55 when instead the Grainger number for this 8000-812-288 is #4UN56. The two pumps are very similar but there a a few differences.
