AIGI 2318A Dual Rotary Cartridge Seal
The AIGI 2318A is a dual rotary cartridge seal built on AIGI's internationally patented Cyclone seal technology. Two rotary seal faces come pre-assembled in a single cartridge, combining the self-cleaning, particle-ejecting Cyclone design with the added security of a barrier-fluid dual arrangement. It is aimed at demanding slurry and abrasive pump service.
Product Benefits
- Self-cleaning cyclone flow: The patented cyclone geometry induces a fluid flow that keeps the seal faces clean and cool while rotating particles back toward the pump.
- Flushless slurry sealing: That flow supports operation without a flush, doing away with the external flush water that conventional slurry seals depend on.
- Dual-seal security: The dual arrangement adds a second line of defence: if the process-side faces are challenged, the barrier-fluid side keeps the seal secure.
- Cartridge convenience: Everything arrives as a pre-assembled cartridge, so installation needs no delicate on-site setting of seal faces.
Where It's Used
- Slurries with particles: The 2318A is intended for slurries and abrasive media containing particles.
- Where single seals fail: These are exactly the services that destroy plain single seals.
- Typical industries: Pulp and paper, mining, metals processing and power plants are its usual homes.
Good to Know
- Rotary-face member: This is the rotary-face member of AIGI's dual Cyclone cartridge family; the companion AIGI 2318T uses stationary seal faces instead.
- Selection depends on duty: Choosing between the two depends on the equipment and operating conditions.
- Built to specification: The double Cyclone configuration is supplied to specification: dimensions, materials and operating limits are defined per application.
