Pump Packing Material — Seal systems

Description

1. Product Overview

This pump packing material is a precision-engineered sealing solution designed for centrifugal, rotary, and reciprocating pumps in heavy industrial environments. Its primary use is to control leakage along the pump shaft while minimizing wear and heat generation. The key value proposition is extended service life under high-pressure, high-temperature, and chemically aggressive conditions. Strategically, it reduces unplanned downtime and total cost of ownership — a critical lever for asset-intensive industries.

2. Key Specifications & Technical Characteristics

• Chemical composition: High-purity PTFE / graphite / aramid fiber blend (or carbon fiber reinforced, depending on variant), with proprietary lubricant impregnation

• Purity level: ≥99.5% active seal成分, no fillers that degrade thermal stability

• Physical characteristics: Square-braided dense profile; color-coded per grade (black – graphite, off-white – PTFE); density 0.9–1.5 g/cm³; cross-section sizes 3mm–50mm

• Packaging options: 1 kg, 5 kg, 25 kg sealed spools or coils; bulk master cartons with desiccant

• Shelf life: 5 years in original, dry, UV-protected packaging

3. Core Industrial Applications

• Primary industries: Oil & gas, chemical processing, power generation, marine, pulp & paper, mining dewatering

• Operational use cases: Main shaft seals in API 610 centrifugal pumps, slurry pumps, boiler feed pumps, and rotary gland steam valves

• Performance advantage: Lower friction coefficient (≤0.08) than asbestos-based or pure PTFE alternatives, enabling higher shaft speeds (up to 25 m/s)

• Efficiency / durability benefit: 3x longer packing life in abrasive media vs. generic die-formed rings; reduces flush water consumption by 15–20%
