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
Title: overheating?

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

but I tried running it, sometimes after 5 minutes it shuts down, sometimes not so its no really reliable. My other one pulls safrole at 82 so I dont worry too much about this one for now
