The Ultimate Guide to Style 50/50 Braided Mechanical Packing

Finding the right braided mechanical packing for your pump or valve is crucial. When dealing with harsh conditions, mechanical instability, or abrasive materials, you need a packing that delivers strength, heat dissipation, and durability.

That’s where our Style50/50 stands out.

In this post (and in the video below), we’ll show you why this is the go-to packing for high-particulate, high-mechanical stress environments.

What Is Style 50/50?

Style 50/50 gets its name from its unique composition, a 50/50 blend of Kevlar (aramid yarn) and fiberglass. This combination creates a packing that is both incredibly strong and able to dissipate heat efficiently.

Kevlar is known for its toughness, while fiberglass helps distribute heat, preventing excessive wear and tear on your equipment.

Why Does the Blend of Kevlar and Fiberglass Matter?

In traditional stuffing box applications, many braided packings have uneven densities due to the way the fibers are woven.This can create air pockets and weak spots, leading to premature failure.Additionally, Kevlar alone is not heat-conductive, which means it traps heat at the shaft, potentially causing damage.

We solve this with our Style 50/50 packing by pre-twisting the Kevlar with fiberglass before braiding. This process creates amore uniform yarn structure, eliminating gaps and ensuring even density throughout the packing.

The result? A mechanically stable, high-performance packing that lasts longer and withstands extreme conditions.

What are the Benefits of Style 50/50?

●     Unmatched Strength: Kevlar fibers provide high tensile strength, making this packing resistant to tearing and abrasion.

●     Superior Heat Dissipation: The fiberglass component allows heat to spread evenly, preventing hot spots that can degrade packing materials.

●     Dimensional Stability: The uniform braid structure prevents shifting, rolling, or deformation during operation.

●     Ideal for Tough Applications: Designed for pumps, valves, and stuffing boxes that handle high-pressure, abrasive slurries, and extreme mechanical forces.

Where Can You Use Style 50/50? Ideal Applications

This packing is ideal for demanding applications, including:

●     Slurry pumps

●     Dredge pumps

●     Sand and gravel pumps

●     Washers

●     Certain valve applications

Style 50/50’s rugged construction and advanced braiding technology make it the go-to choice for industries that demand reliability.
