Product Detail

PAN Fiber Packing – PTFE Impregnated Square Braided Packing for Chemical Pumps and Valves | Model KXT P603

PAN Fiber Packing (Model KXT P603) is a square braided gland packing made from high-strength polyacrylonitrile (PAN) synthetic fibre, pre-impregnated with PTFE and a special lubricant, then re-impregnated during braiding. The result is a dense, dimensionally stable packing with excellent sealing, self-lubricating and chemical-resistant performance across a wide pH range.

It is a widely-used, cost-effective choice for chemical industry pumps and valves handling strong alkalis, strong oxidizers and general aggressive media — where the working temperature does not exceed the PTFE service limit.

QUICK REFERENCE

Model: KXT P603
Construction: Square braided, PTFE impregnated
Temperature: -40 to +260°C
pH range: 2 – 12

Performance Advantages

01	Multi-service capability Handles a wide variety of chemical media — from strong alkalis to strong oxidizers — within the pH 2 to 12 range.
02	Cost-effective Economical packing that reduces operating cost without sacrificing sealing performance in routine chemical service.
03	High extrusion resistance Dense braided construction resists extrusion under gland load, even in high-pressure service.
04	Self-lubricating PTFE and special lubricant allow low friction against the shaft, reducing wear and heat build-up.
05	Chemical resistance Good resistance to acids, alkalis and oxidizers across the whole pH 2–12 window.

Frequently Asked Questions

Q1: What is PAN Fiber Packing made of?

It is square braided from high-strength polyacrylonitrile (PAN) synthetic fibre, pre-impregnated with PTFE and a special lubricant, then re-impregnated during braiding for a denser, more stable structure.

Q2: What pressure and speed can it handle?

Rotary pump service up to 20 bar, reciprocating pump service up to 80 bar, and static sealing up to 100 bar. Maximum rotary speed is 20 m/s. All ratings apply within the -40°C to +260°C temperature range.

Q3: What media is it suitable for?

PAN Fiber Packing is suitable for strong alkalis, strong oxidizers, acids and general chemical media within a pH range of 2 to 12. It is commonly used in chemical industry pumps and valves.

Q4: What cross-sections are available?

Square cross-sections from 3 mm × 3 mm up to 25 mm × 25 mm. Supplied in 5 kg or 10 kg spools, or pre-cut into rings to match your shaft diameter. Custom sizes on request.

Q5: Can I get a free sample before ordering?

Yes. We offer free samples of standard PAN Fiber Packing so you can verify density, cross-section accuracy and braiding quality before placing a volume order.
