Excessive Vibration/Noise in pump

[selectstar]

It is bolted to the concrete. Here is the youtube I posted. It is not a good indication of how loud this really is, but you'll get the idea.

When depressing the plastic pump it is quieter vs the electric motor which tells me most of the vibration seems to be coming from that part of the pump.

That sounds like normal high speed (3600 RPM) pump noise, amplified by direct contact with the slab. Unfortunately, standard 3600 RPM pumps ARE intrinsically noisy.

Unbolt it, and slip a door mat under it. I think you'll find that greatly reduces the noise.

But, if you really want it to be quiet, convert to a two speed pump, and run on low most of the time. Low speed, on most pumps, uses ~1/4 the electricity, but moves ~1/2 as much water . . . and is much, much quieter.

I'll try the door mat suggestion. Converting sounds nasty, is it an involved process?

Actually, I did mean convert in place -- you have to replace the motor, seal, and possibly impeller. Usually, you have to add a heavy duty switch, or timer.

I never know how advanced the DIY skills are, of various posters here. Conversion in place is a moderately advanced job, costing a DIY'r ~$300 - 400, but possibly saving you $100 - 200 per year.
