Advantages of KXT P307 Over Standard Packings

Why Choose Aramid

Performance Advantages

  • Superior lubrication — less wear on the shaft and higher shaft speed capability
  • Very dense packing — suited to high pressure and high speed applications
  • Extremely durable and abrasion resistant — handles granular and abrasive media
  • Lasting resilience — maintains gland pressure between re-tightenings
  • Low thermal expansion — stays in place through temperature cycling
  • Low coefficient of friction — reduces running temperature and shaft sleeve wear

Application Advantages

  • Impregnated with PTFE dispersion — improved chemical resistance and lower friction
  • Silicon-treated for quick and easy break-in — reduced commissioning time
  • Excellent replacement for PTFE-impregnated asbestos packing — no asbestos handling risk
  • Works with most chemicals across the full pH 0–14 range
  • Suitable for rotating and reciprocating equipment, mixers and agitators
  • Recommended for superheated steam, slurries, petroleum derivatives, solvents and liquefied gases

Frequently Asked Questions

Buyer Q&A
What is KXT P307 aramid fiber packing used for?

KXT P307 is a braided gland packing for rotating and reciprocating equipment in abrasive and granular service. It is used on centrifugal, rotary and reciprocating pumps, valve stems, mixers and agitators. Common industries include pulp and paper mills, petroleum refineries, chemical plants, caustic soda production, mines, quarries and sewage treatment plants.

What pressure and speed can KXT P307 handle?

Rotary pump service: 80 bar. Reciprocating pump service: 200 bar. Static sealing: 300 bar. Maximum rotary speed is 20 m/s. For mixed-motion equipment, use the lowest applicable limit. Send your operating conditions and Kaxite will confirm the recommended cross-section and ring count.

What is the temperature and pH range?

Service temperature range is −100 °C to +280 °C. pH range is 0–14, suitable for acids, alkalis, solvents and general chemical service across the full pH range. Density is 1.4 g/cm³.

Why choose aramid over PTFE or graphite packing?

Aramid fiber offers extremely high tensile strength, lasting resilience and excellent abrasion resistance — a combination that PTFE and graphite packing cannot match. That makes KXT P307 the preferred choice for granular and abrasive media where a standard packing would wear out quickly. It is also an excellent asbestos-free replacement for PTFE-impregnated asbestos packing.

What media is KXT P307 suitable for?

Superheated steam, slurries, petroleum derivatives, solvents, liquefied gases, water, oil, diluted acids and lyes, paints and varnishes, and general chemical media across the pH 0–14 range. It is not recommended for strong oxidizing agents or media that attack aramid fiber at high temperature.

Can I get a free sample before ordering?

Yes. A free sample of the exact cross-section is available for qualified buyers so you can run it through your own gland and check braid tightness, break-in behaviour and surface finish before placing a production order.

Do you provide material certificates and quality documentation?

Yes. Each shipment includes a material data sheet covering fiber type, impregnation, construction, density, pressure, speed, temperature and pH range, plus batch traceability and a dimensional inspection record. Third-party inspection can be arranged on request.

How do I request a quotation?

Send your cross-section size, shaft diameter, stuffing box dimensions, working medium, operating pressure, temperature, shaft speed, quantity and destination port. Kaxite replies within 24 hours with a factory-direct quotation, lead time and packing details.
