Cartridge seals
TSB mechanical seals for reliable operation and fast and easy maintenance
TS1, TS2 and TS2P cartridge seals are designed as universal shaft seals for the seal chamber of the standard gland packing casing cover and for the standard shaft sleeve of the gland packing.
- The seal is fixed on the pump shaft or on the shaft sleeve by set screws and into the casing cover by studs and nuts utilizing fixing slots (4x90°) on the seal flange.
- Since cartridge seals can be fitted to the standard casing cover of all kinds of pumps and rotating flow machines, it is possible to use the same seal types in a variety of pumps and other machines.
