Hi David,
I've never used a Duo3 but as long as the power configuration is the same as
the 2.5 - it should be fine.  We've moved our pumps out of the Delta-V
cabinet since it tends to be a bit cramped in there and the pumps get pretty
hot.  Double check the dimensions to make sure the Duo3 will fit to allow
for cooling, head space for attachments, etc.

Subject: [ISOGEOCHEM] Duo 2.5 replacement on the Delta V

Dear List,


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.
