mechanical seals

? Semi-split? Balanced? Independent of direction of rotation? Single seal Semi-split mechanical seals are used if there is a sufficient axial clearance to pull off the seal housing and seat hou- sings until the sliding parts are accessi- ble. i.e. only the wearing parts proper, such as the seal face and stationary seat as well as O-rings are split. The seal face and stationary seat, springs and O-rings can thus be replaced with- out requiring complete disassembly. Springs are arranged to be protected from the medium. The split stationary seat can be used in either side.
