John Crane’s Type 93AX: A Benchmark for Co-axial Separation Sealing Technology
Separation seals are essential for sustaining uptime in rotating equipment such as compressors. Positioned between a dry gas seal and a compressor’s bearing, a separation seal protects the dry gas seal from bearing oil contamination. If the dry gas seal is compromised, a separation seal is designed to minimise process gas from escaping into the atmosphere.
John Crane is pleased to introduce the Type 93AX next generation in sealing technology. This innovative separation seal is designed to enhance protection against dry gas seal contamination and failure, using TriHex grooved technology to maintain a high stiffness barrier gas film between separation seal faces. It operates in a non-contacting manner, is highly efficient and is specifically designed to function in multiple modes, including separation gas failure mode.
The Type 93AX delivers numerous benefits, such as improved safety, reliability, energy efficiency and emissions reduction. It has the potential to minimise seal wear, thereby extending compressor life and cutting maintenance costs.
It supports sustainability goals by reducing nitrogen consumption by up to 81% compared to conventional separation seals and is designed to minimise the release of process gas if a dry gas seal is compromised. Compatible with John Crane’s existing range of dry gas sealing solutions, the Type 93AX co-axial separation seal is suitable for the rigorous operational demands of the energy and process industries, as well as clean energy applications, including hydrogen and CCUS.
