The transmission seal serves as a critical component in addressing sealing issues encountered by centrifuges within automated production lines of various industries, including chemical, pharmaceutical, and salt manufacturing. These centrifuges require their axes to rotate while enduring significant axial forces. Additionally, high-pressure hydraulic oil must flow through the sealing device into the hydraulic cylinder to generate axial thrust. The transmission seal's design and operational principles are tailored to meet the precise demands of these centrifuges.
