Dry running seal
The “RRG30” is a dry contact containment seal that has been designed in compliance with flushing plan No. 70 under API682.
The sealing face is grooved for the purpose of load reduction, and special carbon of enhanced dry running resistance is used. Thus, this seal takes measures for longer service-life in terms of structure and material. It ensures sufficient sealability and high strength even in emergency situations, such as inner seal fracture, etc.
Pressure: Operation is enabled at 4.2 MPaA for at least 8 hours in an emergency.
Peripheral velocity: 25 m/s max.
Shaft diameter: φ30 to 130 mm
