Description A high performance 'white' gland packing, braided from fine yarns of tough synthetic aromatic polymer fibre.
The yarns are texturised and impregnated uniformly and deeply with PTFE dispersion to a high concentration, before being braided over a central core of temperature resistant white elastomer.
A silicone-free, inert and colourless lubricant is incorporated during the manufacturing process to provide swift and easy running-in on dynamic duties.
Typical applications Gland sealing on rotary or reciprocating pumps and valves that handle highly abrasive slurries or aggresive chemical solutions in the mineral, pulp and paper, wastewater and chemical processing industries.
It is also recommended for water, aqueous solutions and other media in processes where a clean white, non-staining gland packing is required.
Arasele proves particularly effective in applications where its rubber core enables the packing to absorb the eccentric movement of shafts or rams that run out-of-true. Its construction can also provide the packing with swift recovery from thermal or pressure shocks and cycling.
Prime features
Kinder to shafts than traditional 'yellow' packings.
Can eliminate unnecessary wear under adverse operating conditions.
Can significantly reduce users' stockholding requirements by providing longlife gland sealing for most pumps and valves on a site.
Excellent resistance to chemical and abrasive media.
Resists hydrolysis - ideal for steam, water and hot aqueous solutions.
Better thermal conductivity than most 'white' or 'yellow' packings.
Can absorb eccentric shaft/ram actions and thermal/pressure shocks and cycling.
Chemical properties Compatible with media in the range pH 0-13, including steam, water, fuels, oils, solvents, acids and alkalis. (Note: this chemical resistance is better than that of traditional aramid-based packings.)
