Flanges for GUR rubber pipes
For pipes terminated with loose flanges we provide split flanges. They allow simple exchange of worn pipes without the sometimes very costly renewal of the flange. This is especially useful for flanges made from special metals or having exceptional measures. We gladly give advise to our customers about possible individual flange constructions.
All our flanges have a sealing front termination consisting of core rubber. Integrated O-rings provide safe sealing to immuG-flanges and others. There is no need for additional sealings.
For safe function of our sealing-system we refer to keeping the mounting instructions.

The construction has proven itself up to the highest pressure levels; they are used as standard by immuG Rohr + Schlauch GmbH up to NP 65. The FL flange can be used for any purpose and is easy to assemble thanks to its unlimited rotatability. This accounts for the why the construction is so lightweight.

Hoses with the FR flange are therefore particularly suitable for assembly in rough and cramped conditions.

Expanding flange EF

In order to solve to this problem the EF (expanding flange) was developed in which a wear reserve is available in the flange area – the flange expansion normally averages one to two nominal width jumps. The goods being transported erode the wear reserve away until a flow channel has been created which corresponds to the wear pattern on the pump side. The textile pressure carrier must not be affected during this process. The components with the EF flange achieve an operating life that is usually realised with our normal flanges on new pumps.
A divided auxiliary flange that is laid behind the pump flange, depicted in the technical diagram and designed according to the customers’ actual conditions is included in the delivery. Instead of the auxiliary flange, adapter plates can also be used. These are fitted with a rubber inlay and therefore also feature a wear reserve. These are all included in the delivery.
EF equipment is suitable for the components of the GUR system and is also suitable for hoses.

With the FR flange the forces that affect the textile reinforcement of the hose are directly transferred to the flange. Guiding the textile layers between the flange and the blank serves to attach the textile layers. The large sealing surface made of core material with embedded O-rings means that this flange is insensitive to cants during assembly.
Hoses with the FR flange are therefore particularly suitable for assembly in rough and cramped conditions.
