AIGI 22SC Silicone-Core High-Temperature Packing
AIGI 22SC is a high-purity carbon-fibre gland packing built around a single resilient silicone-rubber core. The elastic core gives the braid better memory, letting it follow radial shaft motion and vibration while keeping leakage under control. It is designed for high-temperature pump and valve applications.
Product Benefits
- Resilient core memory: The silicone core lets the packing spring back instead of taking a permanent set, so it maintains excellent leakage control with minimal gland adjustment.
- Less maintenance: Fewer maintenance visits to the stuffing box are needed, and the packing is genuinely easy to use.
- Protects the equipment: Consistent, moderate gland load protects the machine: 22SC controls leakage effectively while drastically reducing shaft damage.
- High-temperature fibre: The heat-resistant, high-strength, high-purity fibre keeps performing at temperatures that defeat ordinary packings.
Where It's Used
- Hot pumps and valves: 22SC is intended for high-temperature pumps and valves handling steam, water, solvents, acids and alkalies.
- Wide pH tolerance: Its broad pH range makes it suitable for a wide spread of process media from a single stock item.
- Rotating and reciprocating: It serves rotating shafts at high surface speeds as well as reciprocating equipment.
- Higher valve pressures: On valve stems it withstands substantially higher pressures than in pump service.
Good to Know
- Black single-core braid: The black braid combines carbon and graphite fibre with a single silicone-rubber core.
- State the duty: Rated pressure depends on the motion involved (valves tolerate far more than rotating pumps), so state the duty when selecting.
- Multi-core upgrade: For equipment with more extreme radial motion or heavy vibration, the multi-core AIGI 22MSC offers even more resilience.
- Natural default choice: The single-core 22SC is the natural pick for typical high-temperature duties with moderate shaft movement.
