It extends equipment reliability, even with variable process conditions, by addressing the fundamental challenges of low vapor pressure margin light hydrocarbons.
Its low face contact pressure means less seal-generated heat and less startup torque at the same low-emissions level of typical contacting seals.
It utilizes Flowserve Precision Face Topography with a wave pattern custom engineered for the physical properties of low vapor pressure margin light hydrocarbons.

It satisfies all API 682 design and qualification test requirements for unpressurized dual seal arrangements.
It is based on standard QBQ seals, so retrofits easily solve existing low vapor pressure margin problems and new applications start with minimal inventory impact.
Arrangement 2 QBQ LZ seal with dry running GSL containment seal provides near-zero emissions sealing.
