PTFE packing with aramid fiber corner
Item No.: JSP-AR30
Multi-yarn packing, the corners of packing are made of aramid yarns impregnated with PTFE, while the friction faces are made of pure PTFE yarns. This structure enhances the lubrication ability of aramid fiber and improves the strength of pure PTFE. Multi-yarn in zebra braided packing consists of pure PTFE and aramid, lubricated with silicone oil.
The Aramid Yarn is dipped in PTFE dispersion and saturated and sealed with the PTFE particles to protect the Kevlar fiber from chemical action. The PTFE provides the packing with greater resistance to chemical inertness, lower coefficient of friction and prevents damage from chemical fluids. The braided aramid / Kevlar corner can reduce extrusion and increase pressure and strength characteristics.
The packing is good for general service, agitators, rotating and reciprocating pumps and is recommended for mild acids, caustics, difficult chemicals, air, gases, solvents, oils, general plant applications.
Graphite PTFE packing with aramid corner
Item No.: JSP-AR40
Graphite PTFE Packing with Aramid fiber corner packing is a high-quality combination of PTFE/graphite yarns diagonally braided with corners of aramid fiber to reduce gap extrusion. This is a special packing for applications at the high-pressure range and simultaneous oscillating movements as in plunger pumps.
The graphite / PTFE with Aramid corners Packing is designed for pump and valve and used in corrosive and abrasive applications. It‘s suited for equipment like valves, centrifugal, rotary and reciprocating pumps, mill stock pumps, agitators or any other service where strength and good lubricating qualities are needed.
The gland packing can be used in oil & gas, power plants, refineries & petrochemical plants, wastewater treatment, sugar plants, pulp & paper industry, marine services.
By using this packing, we can extend shaft life and protect from packing extrusion at the back of the gland.
We can also provide Zebra type Aramid PTFE Packing, please contact our sales team for more information.
