I'm currently running 2 5975s, one coupled with a pfeiffer duo3 and the other with a duo2.5. The 2.5 is leaking like crazy and I'm looking for an alternative with longer lifetime. Our duo3 is going great and has been for maybe 4 years. If you had to swap out a 2.5 for something more reliable, what would you choose? Older rotary vane pumps? Dry scroll? I'm weighing options and would love to hear what others would do.
