Pressure: 2 bar
shaft size: 55mm
rpm: 1500


Should be used a metal bellow seal?
Double seal or simple with quench?
Elastomers? Viton is Ok or it is too tight?

1. If cost is not consideration, metal bellow seal will be better. It avoids dynamic elastomer. API Plan 11, 62.

2. Pusher type seal with viton elastomer also will be OK. If pump has jacket cooling Plan 02, 52 will be OK.

Plan 62 with steam water?

Regarding the plan 52, with barrier fluid would be appropiate? The same oil to low temperature?

You should use single high temp metal bellows with API plan 02 & 62 (LP steam or N2. Using pusher seals is on the border line for viton buy you can use perfluoroelastomers. Plan 02 because VP should be very low. plan 62 to stop coking.
