6095 Issue- Buzzing

[fishnugget]

When one of my 6095 ramps up from 30 -60% it buzzes. My other pump does not. This happens every 30 seconds or so.

Any ideas?

These pump are only 5 months old and have been cleaned recently

Either the disk is loose or missing, or the propeller assembly (drive unit) fits too loose. I would try swapping drive units between pumps and see if it follows the drive unit. Air in the pump can also be a cause right after service, it can take a few days to purge all the trapped air.

They have never been out of tank. No Service done. What disk are you speaking of?

What is the drive unit.

Sorry

You said they were cleaned recently in your first post? At 5 months old they are due for a full tear down and cleaning in vinegar and water, this needs to be done at 4-6 month intervals depending on Calcium and KH levels. Part 6055.740 is the disk I am referring to, it is at the base of the shaft down in the pump and is a wearing surface within a shock absorbing cup (black disk in a blue cup) the propeller spins on this surface. It can fall out or stick to the bottom of the propeller, it is a critical part and the pump will be noisy or have trouble starting without it.
