  • single end, unbalanced, dependent direction of rotation, rubber bellow, bellow transmission. This component has a compact structure with good compatibility and easy installation. The bellow can provide support against the pressure to eliminate indentation and corrugation. The bellow and the spring provide pressure compensation to the seal faces. The rubber bellow design prevents possible radial run-out so that the floatability of the rotary ring is increased.
  • This mechanical seal is also known as KSB Part No. 433 mechanical seal. Many other pump manufacturers such as WILO are also using the same type of mechanical seal as their standard sealing solutions.
