Model Introduction:
The KLBM-B-1 bellows seal is constructed by welding a series of diaphragms together at their edges. Each set of welded plates provides a fixed axial movement along the shaft. This design eliminates the need for springs and offers flexibility to the seal. The self-cleaning and non-clogging construction makes it ideal for harsh environments. With excellent dynamic performance, this model is suitable for high-temperature and low-temperature applications as well as for handling high-viscosity media.
