Metallic coupling

[pzesco]

I am supplying a centrifugal multistage pump. My customer is asking for a metallic coupling with spacer. Could I offer him an elastic coupling with spacer and rubber blocks? Cast iron coupling is also accettable?
Thanks

Horizontal or vertical pump?
Carrying thrust load or not?
Rigid or flexible?

What HP, RPM and pump shaft diameter?

I would offer something like the Thomas DBZ series, that's likely what he wants.
