PANTO – Pantograph Bellows Assembly

Aflex Pantograph Bellows Assemblies consist of two or more bellows elements connected by a system of guiding pantograph arms. The multiple bellows elements enable the assembly to absorb large axial movements, while the pantograph mechanism ensures that movement is evenly distributed across each bellows.

By maintaining equal loading, the pantograph arms prevent overextension of individual bellows elements, reduce instability, and contribute to improved cycle life. As the assembly is unrestrained, it will transmit pressure thrust onto the pipeline. To prevent damage or misalignment, the system must be correctly anchored and guided in accordance with EJMA.

The PANTO assembly can be used for many different types of piping applications. It can commonly be used on bridges and drainage lines.
