Look under products, rotary vane pumps
You will find specs for those pumps.
The e2-m2 isnt there anymore but the e2-m1.5 is so I guess it would be around that

I wish I could tell you its a good pump but I dont know since the one I have sometimes stops for no reason, so I cant really use it. Id have to get it repaired, but the fact that I have another one and that I dont like to answer questions for technicians who, for some reason here, always want to meet with you, makes me change my mind

      overheating?  Bookmark   

maybe it's overheating?  try putting a fan blowing directly on it, and see if it still happens.

There's some good information on repairing vacuum pumps on the web page linked to in Post 420877 (lugh: "Vacuum Pumps", Chemicals & Equipment) and some very good advice from a long time hive bee that has worked for SWIL more than once in Post 245579 (lugh: "Re: Welch Duosel Vacuum", Chemistry Discourse) smile
