Latest Patents

Rathburn holds a patent for a "Bellows seal with drive collar for reverse pressure capability." This invention is designed to seal a low-pressure area from a high-pressure area, effectively containing process fluids. The seal features an outboard seal positioned along a rotatable shaft extending from a machine body, and an inboard seal that is axially spaced from the outboard seal. This configuration creates an annular chamber for containing a buffer fluid. The inboard seal consists of a stationary assembly attached to the machine body, which includes a stationary seal ring with a sealing face. Additionally, a rotating assembly attached to the shaft features a rotating seal ring that maintains sealing contact with the stationary sealing face. A drive collar is strategically placed to ensure the sealing relation is preserved even when the buffer fluid pressure is lower than that of the process fluid.
