CM19B/1B
Tandem spring pusher seals
Performance capabilities:
● Pressure： MPa 0~6.0
● Temperature：-40~260 ℃
● Speed：≤25m/s
Descriptions:
√ Applied in high pressure medium, like, light hydrocarbon, aromatic hydrocarbon, ethylene, propylene ,etc
√ Prevent medium leaking into the atmospheric, usually micro leakage inside should be discharged into the flare system
√ High pressure seal in process side, the unique design of the primary ring is beneficial to reduce the deformation of seal faces and increase the heat dissipation area
√ Short axial dimension and compact designs
Features:
√ Double seal with tandem arrangement
√ High pressure seals in process side
multiple springs, rotary
√ Torque transmitted by lugs
Dent drive
Recommended applications:
√ Refining & petrochemical
√ Coal chemical
√ Chemical
√ General industry
Piping plans:
√ Process side:API682 PLAN 11, 21, 32
√ Atmospheric side:API682 PLAN 61, 62
