I got the pump surplus about 20 years ago.  The pump body is mounted on a 
steel plate and a 1/2hp electric motor drives the pump via a flex coupling.

Your best bet would be to go to an air conditioning supply house and get one 
of the pumps they use to evacuate A/C systems.  Those pumps are designed to 
pull a good vacuum and run all day and they would cost _much_ less than a 
pump from a laboratory supply company.
