RE: Leaking

We have had to redesign some components to make our rotary joints more reliable. Of key importance make sure that the washpipe does not deflect off center when pressured resulting in loss of seal energization and eventual leakage from the lower seal. The second area to pay attention to is the surface finish and coatings used on the lower seal. You need to minimize the friction generated when the seal is energized or running dry.
