Edwards 18 E2M18 Rotary Vane Vacuum Pump -Parts

Current Stock:

Product Description

Manufacturer: Edwards

Model: E2M18

Condition: For Parts or Not Working. This pump is in Fair cosmetic condition.  The labels are all illegible except for the side plates.  There are some minor spots of surface rust at the corners of the motor and on the inlet fitting outside.  Judging from the physical dimensions and the Edwards 18 on the side, we are pretty sure this is an E2M18 pump.  There are lots of spots of residue from old adhesive labels and tapes outside, and permanent marker writing as well.

Please NOTE: the fan cover has ALL the mounting holes broken as well as a big crack on one side.  It stays on with just friction, but can be pushed to where it rubs the blades; but you may want to invest in a new fan cover.

Please NOTE: this pump has been drained and will ship WITHOUT oil.  You must refill the oil before returning this pump to service. The photos show the exact item(s) the buyer will receive.

Notes: This pump is in Mostly-working condition. During startup and shutdown, we noticed an unusual whirring noise that seems to come from the joint between pump and motor; we are not sure what caused the noise but that's why we're selling this lot AS-IS.  It pumps down quickly and our vacuum gauge eventually reads 1 millitorr (as close to 0.75 as we can measure).  The system buzzes and hums during operation like a vacuum pump.  This pump came to us with clear oil in the sight glass, and it drained out clear after testing, with only a small amount of very fine black residue at the very end of the draining.  No other testing was done. No manuals, cords/cables, or additional items are included if not listed or shown.
