QS300
Seal for Compressor/Blowers
Three-segmented seal
The segmented structure ensures superb followability in the radial direction. The floating structure achieves superb durability, eliminating the need for cooling. Precision machining minimizes leakage to levels comparable to those of contact type segment seals.
Compared with conventional segment seals, this seal consists of a smaller number of parts and is therefore robust. The shaft is hardly subject to wear, and does not require hardening treatment.
The unit structure allows easy installation and handling. A cartridge structure including a sleeve is also available.
Flammable gas and toxic gas can be completely sealed by using two sets of QS300 in a double seal arrangement (QS310) and a buffer gas.
