Material construction

Jacket lining:

  • High-tenacity polyester yarn, circular woven
  • Totally embedded in the rubber, offering optimum protection against damage
  • Interwoven copper strands for electro-conductivity

 

Lining and jacket:

  • Thermoplastic polyether polyurethane, extruded through the weave in a special one-step production process
  • Electrical resistance less than 10ohms
  • Highly resistant to abrasion, 4–5 times longer service life than nitrile hoses
  • Inside: Very smooth for minimal pressure loss
  • Outside: Very smooth for good flexibility

Advantages

  • Outstanding resistance to abrasion
  • Extremely tough, hard-wearing and durable
  • Resistant to oil, gasoline and chemicals (see resistance table)
  • Resistant to aging and ozone
  • More lightweight and flexible than mandrel-wound industrial hoses
  • 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. For compressed air, the maximum working pressure is 25% of the burst pressure.

 

Maximum working pressure:

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

150 years of
GOLLMER & HUMMEL

What began in 1872 with 1.5 kilometers of hemp fire hose a year hand-woven by master rope-maker Friedrich Gollmer is now a global player in many industries around the world. And yet it’s still a family business – now in its 5th generation.
