Gaspac Dry Gas Seals

The dry gas seal is an advanced sealing technology designed to prevent the escape of process gases in rotating equipment, particularly in centrifugal compressors and pumps. Unlike traditional mechanical seals that rely on a liquid or lubricating film, a dry gas seal operates by creating a thin barrier of high-pressure gas between the stationary and rotating components. Dry gas seals are non-contacting, dry-running mechanical face seals that consist of a mating (rotating) ring and a primary (stationary) ring.

Dry gas seals are mechanical seals but use other chemicals and functions so that they do not contaminate a process. These seals are typically used in a harsh working environment such as oil exploration, extraction and refining, petrochemical industries, gas transmission and chemical processing.

Flowserve gaspac is a typical dry gas seal, and is very popular in the world. because of the below advantages of dry gas seal:

What Is The Leakage Rate Of Dry Gas Seal?

The leakage rate of a dry gas seal is a critical parameter in the operational efficiency and environmental compliance of rotating equipment, particularly compressors and pumps. Dry gas seals operate by employing a thin film of gas to mitigate contact between sealing surfaces, which significantly minimizes wear and tear while providing superior sealing capabilities compared to traditional liquid seals. Typically, the leakage rates associated with high-quality dry gas seals can be as low as 1 to 10 standard cubic feet per minute (scfm), depending on factors such as pressure differentials, temperature variations, and specific application conditions. These advanced sealing solutions are designed not only for optimum performance but also for minimal emissions; therefore, understanding their leakage rates is essential for industries that prioritize safety and environmental stewardship. By maintaining effective control over these rates through rigorous engineering practices and regular maintenance schedules, operators can achieve both enhanced reliability of their machinery and reduced operational costs linked to lost product or gases escaping into the atmosphere.
