main feature:

Meet API617 standard, adopt advanced fluid dynamic pressure groove design to ensure reliable sealing operation;

The use of a light-weight moving ring minimizes the impact of the seal on the dynamic performance of the compressor rotor. The moving ring adopts a floating structure design with metal parts for external circle protection to adapt to various complex working conditions.

With a tandem structure with intermediate comb teeth, the primary seal can withstand all process pressures. The secondary seal is a safety seal that operates under low pressure. When the primary seal fails, it can withstand full pressure operation. The medium leaked from the primary seal is completely carried into the torch by the buffer gas, and only a small amount of buffer gas leaks into the atmosphere from the secondary seal.

Sealed non-contact operation, energy saving, safety and environmental protection, reliable performance, simple operation, and life span of more than 5 years.
