Braided from a specially engineered blend of carbon yarns that are impregnated with a proprietary blocking agent, Marigold 4000 Packing is a non-staining, self-lubricating packing with excellent heat dissipation characteristics. The interlock braiding method used in its construction ensures a tough and resilient packing while the unique blend of carbon yarns ensures extremely low shaft wear and rates of friction
Utilised in both pump and valve applications with temperatures up to 315ºC, Marigold 4000 Packing has a shaft speed rating of 15MPS. When installed in pump applications, it is used with internal pressures of up to 34 BAR. In valves, this rises to as high as 250 BAR.
Boasting excellent chemical resistance (0-14 pH), Marigold 4000 Packing is typically used in applications with severely caustic or corrosive media as well as high speeds and/or high temperatures.
This incredibly versatile packing is available in standard sizes that range from 3.2mm² to 25.4mm² as well as custom sizes produced to suit almost any conceivable application. It is usually suppled in lengths of 8mtrs but is also offered in custom lengths as well as preformed packing rings to match the precise shaft dimensions of your application.
For a similar packing that incorporates a graphite flake lubricant (and offers a higher shaft speed and higher pressure rating, please consider Marigold 4000G Packing).
