Braided packings: LATTY expertise for your equipment
Since its creation, GROUPE LATTY has been recognized for the quality and performance of its braided packings and sealing rings. Thanks to its industrial expertise and constant commitment to innovation, LATTY develops reliable and durable solutions to meet the requirements of the most demanding applications.
A comprehensive range for all industrial applications
The result of several decades of research into technical fibers and lubricants, our range includes nearly 50 qualities of braided packings adapted to numerous operating environments. Our packings are manufactured from over 120 varieties of threads (aramid, PTFE, graphite, carbon, etc.) and over 70 types of impregnations to offer an optimal solution for every sealing need.
LATTY braided packings are designed for use in the stuffing boxes of many industrial installations. They are notably used in rotating machinery such as pumps, agitators, kneaders, mixers, and screw conveyors. They are also suitable for reciprocating machines, including piston pumps, homogenizers, and other equipment subject to similar stresses.
Thanks to the diversity of available materials and impregnations, LATTY braided packings meet the specific constraints of each application in terms of pressure, temperature, speed, and chemical compatibility.
Frequently asked questions about Sealing packings
What are braided packings used for?
LATTY braided packings are used in stuffing boxes to limit or control fluid leaks at rotating shafts or moving rods. They ensure the sealing of industrial equipment such as pumps, agitators, mixers, valves, and piston pumps. Their role is to guarantee the reliability of installations while protecting equipment against premature wear and production shutdowns.
What criteria should be considered when choosing a braided packing?
The choice of a LATTY braided packing depends on several operating parameters. These include the nature of the fluid to be sealed, the service temperature, pressure, rotational or displacement speed of the shaft, as well as the mechanical and chemical constraints of the installation. Compatibility between the packing, equipment, and fluid is essential to ensure optimal performance and a long service life.
Which fiber to choose for a braided packing?
The choice of fiber depends directly on the application. PTFE fibers offer excellent chemical resistance and are suitable for many industrial processes. Aramid fibers are particularly well-suited for environments subject to high mechanical stress and abrasion. Graphited or carbon fibers are preferred for high-temperature applications and demanding service conditions. Each material has specific characteristics that must be selected according to actual operating conditions.
What is the role of the FILCOAT® process?
The FILCOAT® process, patented by LATTY, allows for thorough impregnation of fibers before braiding. This technology ensures a homogeneous distribution of lubricants and protective agents throughout the packing structure. It notably improves chemical resistance, thermal conductivity, pressure stability, lubrication, and corrosion protection. The FILCOAT® process thus helps reduce friction, limit equipment wear, and extend the service life of sealing systems.
Are braided packings suitable for harsh environments?
Yes. GROUPE LATTY braided packings are specially designed to operate in demanding industrial environments. Depending on their composition and impregnation, they can withstand high temperatures, aggressive chemicals, significant pressures, or high rotational speeds. They are widely used in sectors such as chemistry, petrochemicals, energy, food processing, paper manufacturing, and water treatment, where sealing reliability is a major concern.
