Product catalog summary
Application
These flame retardant and antistatic hoses are designed as equivalents to 4SP hoses according to EN 856 standards. They offer high working pressure and enhanced flexibility, making them suitable for tight spaces. These hoses are specifically designed for use in underground mining environments with methane and coal dust explosion hazards. They are compatible with hydraulic fluids (except HFD R, HFD S, HFD T), water solutions, water, and compressed air within specified temperature ranges. They are not suitable for liquids containing castor oil and esters.
Specifications
  • Working pressures range from 210 to 420 bar depending on diameter.
  • Operating temperature ranges from -40°C to +100°C, with short-term tolerance up to +125°C.
Construction
The hoses are constructed according to Stomil’s design ZN-5/13/BZPG, featuring an inner tube of oil and water-resistant black synthetic rubber, reinforced with three braids of high tensile steel wire, and covered with flame retardant, antistatic, abrasion, oil, weather, and ozone-resistant black synthetic rubber.
Certificates
The hoses have MSHA approval for use in underground mines.
