Product Detailed Description

FW 58B and 59B Mechanical Seals for Chemical Centrifugal Pumps, Water Pumps, and Compressors

Structural Features:

single end, multiple springs, balanced, independent direction of rotation, bolt and lug transmission. The way of transmission is simple and reliable. The compensation components are pre-assembled and the seal is easy to install. This component has a compact structure. The spring housing and springs can be pre-assembled for easy installation. Sealing accessories such as the O-Ring can have different materials according to different operating situations. For instance, for refrigeration 58B should use rubber O-Ring; when the medium is corrosive. 58B or 59B can be assembled with itself or each other working together as a double end seal.

Industrial Standards:

DIN24960, ISO3069, GB6556, EN12756

Scopes of Application:

widely used in chemical pumps, water pumps, piping pumps, screw pumps and compressors for industries such as chemical processing, oil refining, petrochemical engineering, chemical fibering, food processing, pharmacy, paper pulp and environmental protection industries. This component can work as an alternative to similar products such as John Crane 58B.
