In my search for a new employer I am sure to come across manifolds
using a 'roughing pump', D-pump and a final vacuum pump. As I am only
familiar with a single pump, can anyone give me some insight on how to pump
with one of these systems?
I've got a pretty good idea how to make poor equipment work, but
am lost when it comes to a good system. Thanks in advance.
Best Wishes,
Sean
