摘要：
A rotary pressure filter apparatus, a sealing device for use with the rotary pressure filter apparatus, and a process of using the apparatus. The rotary pressure filter apparatus is designed to treat a solid-liquid mixture under pressure in successive work zones. A rotary drum moves compartments containing the solid-liquid mixture through the successive zones. The zones are separated by a sealing member, which is designed to reduce pressure fluctuations as the compartments enter a successive zone.
