Product Detailed Description

YL 58U, AKA 58B, 59B, 59U Mechanical Seals for Chemical Centrifugal Pumps, Vacuum Pumps, Compressors and Reaction Kettles

Structural Features: single end, multiple springs, unbalanced (58U and 59U) and balanced (58B and 59B), independent direction of rotation, drive sleeve transmission. This component has a compact structure with small axial dimension and equal force on the sealing surface. This component can work as an alternative to similar products such as John Crane 58B, 58U, 59B, and 59U.

Industrial Standards: DIN24960, ISO3069, GB6556, EN12756
