Leybold Trivac D8B

We need a roughing pump for our turbos. I bought this unit a while ago, and it works, but it also makes funny noises.

Plan

It needs to be opened up. I may have to fabricate and/or purchase some new parts to get it back to a more usable state.

Teardown / Rebuild

  • Fully disassembled pump module

Link to the STL for the shaft seal driver.

For those who wish to replace the shaft seals without being extorted by Leybold, they are regular FKM GR 15x24x6.5 SS 304 spring oil seals. Available as a general commodity item.
