CM15B/19B

Back-to-back high pressure pusher seals

Performance capabilities:

● Pressure: MPa 0~4.0
● Temperature:-40~260 ℃
● Speed:≤25m/s

Descriptions:

√Pressurized double seal, ideal for flammable, explosive or toxic medium with high pressure and high safety requirements
√ Prevent medium leaking into the atmospheric
√ Recommended applications: hydraulic turbine of refinery hydrogenation plants, and rich amine liquid of desulfurization plants
√ Adapt fluctuation of positive and negative pressure difference and pump housing evacuation condition
√ Prevent media leaking into the atmospheric, micro barrier fluid will get into pumped media
√ Back-to-back arrangement, short axial dimension and compact designs

Features:

√ Multiple springs, rotary
√ Internal balanced+ high pressure
√ Dent drive

Recommended applications:

√ Refining & petrochemical
√ Coal chemical
√ Chemical
√ Hydraulic recycle turbines
√ Amine rich turbines

Piping plans:
