Contact SupplierThrough years of experience and continued R&D by Kessels, the most reliable, user friendly and maintenance free method of inter-stage and end steam sealing for Turbines have been found to be the use of Carbon Rings, Labyrinth Seals and Sealing Fins. Kessels offers all the three options in its varied range of Steam Turbines.
Kessels Single Stage Turbines use special carbon ring packing for mechanical sealing of the steam for their ease of use and in-situ replacement.
Thespecially designed Labyrinth seals are machined from special grade stainless steel, are of spring backed type and placed between the rotor and the casing to prevent and minimize steam leakage. Under normal operating circumstances, these labyrinth seals do not contact the rotorand do not warrant any maintenance for an extended period of time. The larger Multistage Turbines from Kessels use J-Type sealing fins for mechanical sealing and preventing steam leakage. J-Type sealing fins are significantly safer than regular seals, being easily replaceable and limiting the damage to the rotor by rubbing in the event of an accidental run-away.
