Operates at low differential pressure, reducing gas consumption! The self-centering design minimizes wear even in abnormal conditions.
The "TYPE 93FR" is a non-contact design carbon bush designed to protect the dry gas seal from the intrusion of bearing oil. The segments have a special design that prevents oil intrusion. Separation gas (usually nitrogen or air) is injected between the two segmented bushes, effectively forming a pressure barrier between the bearing and the dry gas cavity. Additionally, advanced materials and design eliminate wear during normal operation, achieving a long lifespan. 【Features】 ■ Non-contact seal that achieves long lifespan, improved reliability, and low heat generation ■ Operates at low differential pressure, reducing gas consumption ■ Specially designed segments further reduce gas consumption ■ Suitable for flowing nitrogen separation gas regardless of the dew point *For more details, please refer to the PDF document or feel free to contact us.
