Alcatel ADP 122L Vacuum Pump, only gets down to 8 millitorr - Parts

Current Stock:

Product Description

Manufacturer: Alcatel

Model: ADP 122L

Condition: For Parts or Not Working. This pump is in Good overall cosmetic condition with a few notable blemishes.  The EMO connector on the rear panel has broken plastic bits and a pushed pin, but still works for EMO bypass contact purposes.  There are a few scratches/dents on the removable covers. The hours meter reads about 69170 hours.  The insides look clean, and the water flow meter is clean inside also.  The oil is a little dark and we don't know when it was last changed, so you will want to do that at least before putting this pump into service. The photos show the exact item(s) the buyer will receive.

Notes: This pump is in Good working condition, but does not attain its rated ultimate pressure.  During our testing, initial pump-down was very fast but it only drew down to 8 millitorr on our gauge.  We are not sure if it needs just an oil change or some other service to achieve its rated ultimate pressure.  Operation is (reasonably) quiet. When water is not running, it sets a FAULT light.  The hours meter slowly counts up.  With the rear panel connectors wired for local operation, the switch on the top/front by the hour meter starts/stops the pump. Specifications listed are for 60Hz operation. No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
