Enhancing Mechanical Seal Reliability in a High-Pressure Marine Application

By employing Vulcan Seals‘ optimised, low-wear sealing solution, a marine equipment manufacturer successfully resolved recurring electrical reliability issues, reduced failures, maintenance costs, and enhanced overall equipment performance without the necessity for significant modifications.

Case Study Overview
A leading marine equipment manufacturer, specialising in high-performance propulsion and fluid handling systems, was facing persistent electrical reliability issues with the mechanical seals in an unusual, high-pressure, deep-sea marine application.

With external pressure exceeding internal pressure, the original European-designed mechanical seal, while suited for short axial length installations, struggled to maintain performance under these demanding conditions, an issue that resulting in:

- Short working height limitations
- High external pressure impact
- Inadequate performance in variable marine conditions

The Vulcan Seals Approach
The Vulcan Seals engineering experts conducted an in-depth analysis of the application, including a review of used mechanical seals from the system.

This evaluation identified opportunities for minor modifications to the mechanical seal chamber, which would enable the use of Vulcan Seals’ shortest-length parallel spring diaphragm bellows mechanical seals.
