Material construction

Jacket lining:

  • High-tenacity polyester yarn, circular woven
  • Specially designed for high compressive strength and tight bending radii
  • Totally embedded in the polyurethane, offering optimum protection against mechanical damage
  • No opportunity for microbe or bacteria growth

 

Lining and jacket:

  • Special drinking water-safe polyurethane, extruded through the weave in a one-step production process
  • Highly resistant to abrasion, 10 times longer service life than coated hoses
  • Inside: Very smooth for minimal pressure loss, easy to clean and disinfect
  • Outside: Very smooth for good flexibility

Advantages

  • Extremely tough, hard-wearing and durable
  • Easy to clean and disinfect, no drying needed
  • Excellent resistance to all standard disinfectants
  • Resistant to aging and ozone
  • Space-saving and easy to use compared to PE or metal pipes
  • Stays flexible at cold temperatures

Pressures

Working pressure:

Specifications apply only to the hose (medium water, 20 °C). The potential working pressure may be lower than specified above for hose lines with couplings due to the nominal pressure of the couplings or the type of assembly.

 

Maximum working pressure:

Approval can only be given by the manufacturer upon clarification of the exact area of application.
