NORRES Schlauchtechnik, in a cooperative venture with RS Roman Seliger, recently became the first manufacturer to develop a special safety clamp system for loading and unloading silo vehicles that fits spiral wire-reinforced polyurethane hoses. This unique product, which is compatible with tank truck, Kamlok and Storz couplings, offers several crucial benefits compared to the traditional method with rubber hoses. The joint innovation will be unveiled at the K 2007 fair from October 24 to 31.
A wide range of free-flowing solids, such as fodder, flour, grain and cement, have traditionally been loaded in and unloaded from silo vehicles by heavy, inflexible rubber hoses with a tendency to age fast. Since there was no other way to load and unload this bulk material, it was not possible to observe the process and the hoses were difficult to assemble. They were also liable to leak within a short time and suffered from excessive abrasion.
Product innovation
NORRES Schlauchtechnik, a leading manufacturer of industrial hoses and hose systems, has now developed a unique alternative to the classic rubber hoses featuring an innovative safety clamp system that fits spiral wire-reinforced polyurethane hoses. This novel solution will in future allow bulk material to be transported using an undeniably superior hose type. Polyurethane is far more resistant to abrasion than rubber, which means the hoses are also significantly more durable. In addition, polyurethane hoses weigh only a fraction of their conventional rubber counterparts and at the same time are much more flexible. RS, an international leader in the field of hose fittings and hose technology, collaborated with the NORRES R&D department to develop the innovative safety clamp system.
Transparent Polyurethane hose
The new safety clamp system for loading and unloading silo vehicles was initially developed for the NORRES AIRDUC® PUR 356 polyurethane hose and reinforced with a diameter of 100 mm. The AIRDUC® profile hose is designed with a spring steel wire firmly embedded in the wall. It is not only flexible but also lightweight with a very smooth interior. The high smoothness of the interior hose surface leads to less deposition of the delivered material and allows gentler material transport – an immense advantage compared to rubber hoses, particularly when conveying food products. What's more, it contains neither plasticisers nor halogens. Above all, however, the process can be simply observed because the hose is transparent. Providing the spiral is earthed, the hose is conductive according to BGR 132, so that static charge and resulting process disruptions are avoided. AIRDUC® also exhibits good resistance to mineral oils, petrol, chemicals, UV and ozone. The polyurethane hose can be used at temperatures from -40°C to +90°C or up to +125°C for short periods. Other hose types and diameters will be added to the product range in the near future.
Connection
The safety clamp system is remarkable for its reusable clamp and its quick and easy assembly. It can be connected to a whole series of popular coupling and connection solutions, such as tank truck, Kamlok or Storz couplings. The hose adapter with the male thread is available in light metal, steel or stainless steel, while the clamps themselves are made of light metal.
The product innovation will be unveiled at the K 2007 fair in Duesseldorf, Germany, from October 24 to 31. You can find NORRES in Hall 7.0, Stand No. A23.
