So yesterday the pump arrived refurbished from the manufacturer (for $3,500). yay!
I attached the pump to the chamber and tried it out. All good.
For about 10 minutes.
Then i start hearing this intermittant “not good” sound. But maybe it’s just some rattling right?
We’ll the rattle turned into a shriek. When the pfeiffer tech heard the sound on the phone he said to send the unit back.
What a drag.
