Rotor Seals

Rotor seals provide sealing functionality for rotating and swiveling movements under high pressure and low velocity. There are two different types of rotary seals: for the stator with dynamic sealing on the inside, and for the rotor with dynamic sealing on the outside diameter of the seal. Except for end seals in rotary distributors, rotor seals are designed for double-acting functionality.
