Graphite
Graphite Gland Packings: for high temperatures
Extreme operating conditions: designed to work stably in the presence of high temperatures, significant pressures, and severe duty cycles.
Dimensional stability and stuffing box adaptability: they maintain their structure over time, compensating for tolerances and ensuring a constant seal without frequent adjustments.
Self-lubrication and low wear: pure graphite and carbon fiber reinforcements guarantee an absence of seizing, minimal wear on shafts and bushings, and reduced energy consumption.
Effective leakage and emission control: designed to reduce fluid dispersion and improve plant safety, even in critical applications.
- Reinforced corners
- Minimizes leakage
- High pressure
3333/4G
Gland packing reinforced with carbon fiber corners
Every single graphite strand and the corners are reinforced with carbon fiber, without the use of additional reinforcements. In pumps, it eliminates the need for flush water and minimizes leakage. It is self-lubricating and does not cause wear on shafts or bushings.
Applications
Universal: paper mills, specifically for pulp and paper, agitators, refiners, pulpers, and condensate pumps. Also suitable for high-pressure steam valves, hydrocarbons, thermal, and nuclear power plants.
Max operating temperature: +450 °C
Min operating temperature: -240 °C
- Anti-extrusion
- For abrasive fluids
- Reinforced corners
3333/4K
Anti-extrusion with Kevlar® corners
Special packing with exclusive construction for pumps handling abrasive fluids. Core made with individual graphite strands reinforced with carbon fiber and diagonal braiding. External carbon fiber reinforcement with Kevlar® yarn corners.
Applications
Used as an anti-extrusion ring to reduce stuffing box tolerances and to protect other packing rings from fluid abrasion. Generally, only one ring (the first ring on the fluid side) is installed in the stuffing box.
Max operating temperature: +280 °C
Min operating temperature: -100 °C
- Patented yarns
- Reinforced graphite
- API 6FB Fire Test Certified
Slade 3300/G
