I have a colleague that recently replaced the Duo 2.5 in a Delta V with an Edwards EM 1.5 and he has been very happy with the alternative. The Edwards is much quieter, runs cooler and seems to perform just as well. The physical size is comparable to the duo.

The Duo 2.5 roughing pump on my Delta V failed and I need a replacement. Pfeiffer no longer sells that model. Can I use their Duo 3? Peiffer wasn’t sure if there were any modifications needed for use on the Delta V.
