A Welch dry vacuum pump with a single-phase AC motor that powers on and hums but cannot be fully tested for actual vacuum output or leakage. Resells to lab equipment refurbishers and research-facility maintenance teams who diagnose and repair vacuum systems. Test the pump for oil mist in the outlet and listen for any internal grinding, which would indicate bearing wear or a seized rotor.
Estimated flip margin and comp range available with Pro. Summary may occasionally contain inaccuracies; check the full description before bidding.
