Black PTFE aramid packing for plunger pump
PTFE Aramid packing combines tightly braided aramid fibers with PTFE lubrication to create a dense, low-friction sealing material in a durable black finish. The structure offers strong resistance to heat, abrasion, and chemically aggressive media, making it suitable for pumps, valves, mixers, and other rotating equipment. Its balanced design limits shaft wear, maintains steady sealing performance, and helps extend maintenance intervals in demanding industrial environments.

Made of graphite impregnated PTFE mixed with used to enhance the corner line aramid to obtain excellent per-formance filler. The cormer wires are reinforced with aramid impregnated with PTFE, creating a synergistic composite material that fundamentally addresses aramid's inherent lubrication deficiency while simultaneouslyelevating the me-chanical strength and structural integrity of the PTFE matrix.This advanced construction effectively prevents wire rup-ture and extrusion under extreme high-temperature and high-pressure condtions, while delivering exceptionallubricity for reduced friction and superior thermal conductivity for optimal heat disipation during demanding operations.
Key Features & Benefits
- · PTFE Aramid provide outstanding mechanical stability, allowing the packing to hold shape and seal effectively even under fluctuating pressure or vibration.
- · PTFE dispersion reduces heat generation, supports smoother shaft movement, and minimizes risk of scoring or sleeve damage.
- · The ptfe aramid packing tolerates gritty slurries, fibrous pulp, and abrasive chemical media, making it suitable for demanding process industries.
- · Resists degradation in hot water, mild acids, alkaline solutions, and many process chemicals, ensuring steady sealing quality.
Typical Applications
- 1. Process pumps handling contaminated or abrasive fluids
- 2. Mixers, agitators, and rotating equipment
- 3. Pulp & paper, chemical plants, wastewater treatment, and general industrial services
- 4. Valves operating under elevated temperature or medium pressure conditions
Installation Recommendations
- · Ensure the shaft or sleeve surface is clean and free from scoring before installation.
- · Install rings evenly and compress gradually to avoid over-tightening.
- · Allow a short break-in period for the PTFE surface to seat properly.
- · Periodic inspection ensures the packing maintains its optimal sealing load.
