Bought a used 250GPH CDL RO from a well known dealer in NH. It was a "couple years old" with new membranes. When I got it, turned out to be an '02 model. But I couldn't send it back, I HAD to start processing. So I'm up the creek. About 1000 gallons into it, she started making a loud screach when the pressure pump was turned on. I called CDL and they said "bearing needs replaced" but it was "ok" to run. Shortly after, she started sparking and quit. The motor will not turn at all and dims the lights real bad.
Anyone experience this problem? I don't know what I need to replace, but I would consider overnighting each possibile part it could be. Is it designed with a coupler? We tried to drop the motor but it only seperated about 1/4" from the pump frame. What is the secret? Did we heat the motor shaft up and weld it to the bearing? We need help bad as we just expanded our operation and we need to process syrup to pay for the investment. Funny this is, I could have paid $1000 more for a new one. I will never buy used again.
