Style 777 SO
Benefits: Style 777SO is almost a double seal based on simplified design to facilitate off the shelf interchangeability. Ideal for most applications and plant standardization. The advantages of similar to double seal features are enhanced by the presence of a Lip Seal, as a secondary seal.
ASSURED QUENCHING: The presence of the Lip Seal makes Style 777SO ideal for use in applications where the pumped product MUST NOT be diluted by any other fluid, usually occurring through flushing. The incorporated QUENCH does not allow mixing.
LEAK FREE ENVIRONMENTAL CONTROL: The incorporated Lip Seal does not allow leakage on the atmospheric side, making Style 777SO, the only seal available for applications where double seals cannot be installed due to high cost or lack of space.
