Rated 3 out of 5 by 2reviewers.
Rated 5 out of 5 by Had this pump for over 2 years now. Boosts the pressure in our plant cooling water loop through a heat exchanger to get the correct volume/flow. Set to start automatically and it just sits there and runs. No leaks, overheated motor or faults of any kind. Our process water is treated which gunks up a fair amount of our metal plumbing, but this pump has been unaffected so far. Fairly quiet, too. February 25, 2016
Rated 1 out of 5 by I've had this product installed for less than one year, and it began to leak. The manufacturer (Grainger# could not supply one #of three# parts for me to purchase, in order to repair the unit. Unfortunately, I purchased the unit well before installation, so I am beyond my warranty period. And also unfortunately, without having one of the potentially necessary replacement parts available, I may not be able to repair the unit.I would recommend researching and purchasing a unit with high reliability, and where the manufacturer can supply repair parts easily #and perhaps take out the extended warranty).
