This is a GAST Vacuum Pump that I found at a Seattle area surplus sale. I believe it is a GAST 65 Series Rotary Vane Vacuum Pump Unit Model 0765-V8B-G32AX powered by a 1/3 HP GE Motor Model C157, #5KC36LN5GX (see pictures). The unit is in lightly used condition, tested, runs strong as intended, fairly clean (see pictures). This GAST 0765-V8B-G32AX Vacuum Pump Unit w/ GE 1/3HP Motor comes as shown in the pictures. Should be of interest to laboratory equipment models-accessories-parts & GAST / Whip Mix / GSE / Vacuubrand GMBH / Jelenko related pumps.
