1. Graphite Packing for Pumps: Reliable Sealing Under Extreme Conditions

Graphite packing for pumps is a braided or die-formed sealing material designed to withstand aggressive fluids, high temperatures, and mechanical stress. It is commonly used in centrifugal pumps, valves, and compressors.

Key Features:
Temperature Resistance: Up to 500°C (932°F) in oxidizing environments and up to 3,000°C (5,432°F) in non-oxidizing conditions.
Chemical Resistance: Resistant to acids, alkalis, and organic solvents.
Low Friction: Reduces wear on pump shafts, extending equipment life.
Flexibility: Conforms well to irregular surfaces, ensuring a tight seal.

Applications:
Oil & gas refineries
Chemical processing plants
Power generation systems

2. PTFE Graphite Packing: Enhanced Lubrication and Chemical Resistance

PTFE graphite packing combines the non-stick properties of PTFE (polytetrafluoroethylene) with the thermal stability of graphite, making it ideal for dynamic sealing applications.

Key Features:
Wide Temperature Range: -200°C to +260°C (-328°F to +500°F).
Excellent Chemical Resistance: Compatible with most corrosive media.
Self-Lubricating: Reduces friction and prevents shaft damage.
Low Permeability: Minimizes leakage in aggressive environments.

Applications:
Food and pharmaceutical processing
Chemical and petrochemical industries
Water treatment plants
