Gland Packing Chesterton 1740 - Extreme Abrasive Resistance & Anti-Extrusion
Product Information: Chesterton 1740 Interbraided Aramid
CV Mulia Jaya Packing presents the ultimate defense solution for pumps handling rough fluids and sludge: Gland Packing Chesterton 1740. This is a high-performance packing woven from Aramid fibers (the same base material used in bulletproof vests), providing exceptional tensile strength compared to other fiber types.
Each yarn strand in Chesterton 1740 is impregnated with PTFE and special silicone lubricants before being interbraided. This construction makes it extremely dense, resistant to high pressure, and impervious to destruction by solid particles like sand or paper stock. It is the premier choice for industrial products in heavy-duty applications where ordinary packing quickly disintegrates or extrudes through gaps.

Product Advantages
Why is Chesterton 1740 from CV Mulia Jaya Packing a mandatory investment for abrasive environments?
- Superior Abrasion Resistance: Aramid fibers withstand the scouring action of solid particles (sand, mud, crystals) far better than synthetic or natural fibers.
- Anti-Extrusion: Due to its strength, this product is often used as Bull Rings (backup rings) at the top and bottom of other packing sets to prevent extrusion through tight clearances.
- Strong and Tough: Will not break or tear during installation or operation under extreme conditions.
- Dual Lubrication: The PTFE and silicone content help reduce frictional heat, which is typically high in standard Aramid fibers.
Product Applications
Chesterton 1740 is specifically designed for heavy industries such as:
- Mining and Mineral Processing.
- Pulp and Paper Mills (Paper Stock Pumps).
- Slurry Pumps.
- Wastewater Pumps containing sand/solids.
- Agitators and Mixers for solid chemicals.
