Why Choose FLUITEN Standard Mechanical Single Seal BL3X?
The BL3X is a balanced , bidirectional , multi-spring component seal with a Type X pinned stationary seat , engineered for large-diameter shafts on medium to high-pressure equipment. Its robust design resists vibration , mechanical stress , and dirty or toxic fluids , making it ideal for heavy-duty machinery like multistage pumps , agitators , and boiler-feedwater systems.
Typical Applications
Multistage pumps , boiler-feedwater pumps , agitators , and other large machinery
Handling dirty , toxic , flammable , or abrasive fluids
Equipment requiring leak-free sealing and mechanical durability under bidirectional rotation
Retrofit or OEM systems with high mechanical and operational demands
Additional Features
Balanced design limits face loading and heat generation
Springs positioned outside fluid to prevent clogging
Type X pinned seat ensures precise axial and rotational alignment
Dynamic FLUIGAM O‑ring provides reliable contact sealing
Modular material options for seal faces and secondary seals (e.g. , SiC , TC , PTFE , FKM)
Double-component cartridge version available to reduce axial footprint and support gas-tight applications
