321968 Teflon Packing

Introducing the 321968 Teflon Packing by Blackmer

The 321968 Teflon Packing Blackmer is a high-performance sealing component designed for use in positive displacement and sliding vane pumps. Manufactured from PTFE (polytetrafluoroethylene), this Teflon packing offers excellent chemical resistance, low friction, and high temperature stability, making it suitable for demanding industrial applications. The packing is engineered with a durable braid construction, ensuring longevity and consistent sealing performance over extended periods of operation.

• Materials: Polytetrafluoroethylene (PTFE) fabric braided with stainless steel wire core for enhanced strength and durability.
• Dimensions: Typically available in rings measuring approximately 1 inch (25.4 mm) in diameter with a 1/8 inch (3.2 mm) cross-section, compatible with standard pump shaft sizes. Exact measurements may vary based on OEM specifications.
• Temperature Range: -100°C to +260°C (-148°F to +500°F), suitable for high-temperature pump environments.
• Chemical Compatibility: Resistant to acids, alkalis, solvents, and most aggressive chemicals, ensuring reliable sealing in various process fluids.
• Sealing Efficiency: Provides a tight and consistent seal, minimizing leakage and extending pump service life.
• Operational Use: Ideal for sealing pump shafts in systems handling chemicals, oils, and corrosive fluids.

Use Cases and Suitability

The 321968 Teflon Packing Blackmer is suitable for use in demanding chemical processing, oil and gas, and pharmaceutical systems. It is especially effective for applications requiring high chemical resistance and low friction sealing. This Teflon packing is designed for pumps that operate under moderate to high pressure and temperature conditions. It is an ideal choice for replacing worn packing in existing pumps or integrating into new pump installations where reliable sealing is critical.

For budget-conscious operations, this packing offers durable performance at a cost-effective price point, making it a preferred option for maintaining pump efficiency and reducing maintenance costs.

Included in the Package

The package includes the 321968 Teflon Packing ring(s) as specified for your application. Notably, other pump components, such as shafts or gland fittings, are not included and must be purchased separately.

Care and Maintenance

To ensure optimal performance, regularly inspect the Teflon packing for signs of wear or degradation. Periodic lubrication or adjustments may be required based on system conditions. The packing can typically be cleaned with compatible solvents or in situ during scheduled maintenance. No specific warranty is provided; replace as needed after service life or if leakage occurs.
