2hp Spindle Pump and Flow Indicator

Post by ffloyd »

I have been using the 2hp spindle on my HD520 for about 2 years. Today when I turned on the system, the flow indicator would not spin. Further I am detecting an unusual sound from the submersible pump. On inspection, there is water moving through the system as the return line does have water coming out of it. I am in Southern California, so cold weather is not much of a problem. I have distilled water running through the lines with a little bit of RV anti-freeze.

Anyone had similar problems? If so, what is the solution?

I bought a new pump and new flow indicator. The problem apparently was the flow indicator as it would not turn around even though water was flowing. I replaced both pump and flow indicator. The problem is now resolved.

The old pump still works, so I saved it for the next disaster. The flow indicator was no good. That piece is available on Amazon Prime. I purchased another one to have on hand to avoid production delays.

Today, the pump stopped pumping (again) and the spindle has overheated. Now it is still spinning up but making excessive noise. I suspect the overheating caused damage to the spindle motor. Time for a replacement????
