A local thrift store was shutting down and we bought a large Sanborn 500b compressor (5hp) they had - we thought we were getting a deal, but we weren't really. It was virtually used, but soon after we got it hooked up, the pump section froze.
We bought a replacement pump for $200
But, the thing will not fill the tank from empty. It overheats and we have to unplug it (it has no on off switch), let it cool, and start it up again. I'm guessing this is a 50% duty cycle pump - but the compressor has no way to limit run time to 50%, so it just cooks.
If we wanted to replace this pump with a decent 100% duty cycle pump appropriate for 5hp motor, what would I get. They are available all over at a wide variety of prices.
