Granite City ==> vacuum pump 1

This is a small pump for general laboratory work. Very useful in evaporation and distillation work. Comes without oil (requires oil). This pump has a vacuum gauge (no glass on the gauge though).

Testing: The pump works fine when started, on the last picture you can see the pump gauge showing about 12 PSI when the pump is operating and the inlet is closed. It has a 1/2 HP continuous duty induction type motor by Century Electric. It looks relatively clean and it seems like it has seen little use.

Requires SAE 30 oil.
