We have had an on-going issue with our WP pump making rattling/vibration noises straight out of a horror film. I have tried replacing seals, loosening/tightening the body, and trying different speeds with the VFD.
It takes almost 8mins for any momentum to build-up to create a spin. Still there is slow spin. Kettle finings have been dialed in according to the manufacturer recommendation, but our trub pile is complete dog crap. No structure, flat as a pancake, very unappealing.
The whirlpool pump outlet, into tangential inlet seems to be the source of the rattling/vibration. When we choke back the valve at the tangential inlet, the rattling goes away. However, the trub pile becomes egg-shaped. Some folks who have tried to help say the issue could be cavitation, but I can't figure how to alleviate that issue.
I will be able to upload videos shortly, and I will post them here.
This is running at 7/10 on my VFD
