58U Mechanical Pump Seal
The 58U Mechanical Seal is a widely used pump seal designed for reliability in various
industrial applications. It features a single-end, non-balanced, multi-spring structure with compact design, suitable for oil, water, solvents, and mildly corrosive media
Q1: What is the 58U Mechanical Pump Seal typically used for?
A1: The 58U Mechanical Seal is widely used in centrifugal pumps (such
as IH, CZ, CHZ, and IS series) for handling water, oil, solvents,
and mildly corrosive media in industries like chemical processing,
water treatment, and general industrial fluid transfer.
Q2: What materials are used in the 58U seal’s construction?
A2: Standard components include:
Primary sealing faces: Silicon carbide (SiC) or tungsten carbide (TC)
Secondary seals: PTFE, NBR, or EPDM elastomers
Springs: Stainless steel (e.g., SS304/SS316)
Q3: Can the 58U seal handle abrasive or high-speed applications?
A3: While suitable for moderate conditions, abrasive fluids or extreme
speeds may require upgraded materials (e.g., hardened SiC faces) or
dual-seal configurations. Consult manufacturers for specific
solutions.
