*Product advantages:
The main form of actuating seal is ripple compensator and floating seal ring, and the seal can be adjusted
and compensated freely, making the seal more reliable and stable. The shell is provided with an observation
hole through which the wear and seal of the sealing ring can be observed at any time.
*Range of adaptation:
Maximum speed: ≤500RPM
Maximum temperature: ≤220℃
Maximum pressure: ≤ 1.8mpa
*Applicable medium:
Saturated steam, superheated steam, superheated water
