No support equipment needed! The standard design is compatible with most single-stage turbines.
The dry gas seal "TYPE 28ST" that we handle significantly reduces steam leakage by about two orders of magnitude compared to conventional segment carbon rings and labyrinth seals, which combine proven rotary groove technology with high-temperature secondary seals. This steam-lubricated end-face cartridge seal automatically responds to sudden changes in operating conditions to maintain a safe and reliable face gap. In addition to the groove portion of the seal known as the "seal dam," a specially designed groove directs steam radially inward, ensuring a stable seal face gap of 2.5 to 5.1 microns. 【Features】 ■ Reduction of steam contamination by bearing oil ■ Standard design suitable for most single-stage turbines ■ Reduction of noise and hazards associated with steam leakage ■ Compatible with both unidirectional and bidirectional rotation *For more details, please refer to the PDF document or feel free to contact us.
