John Crane Introduces the Next-Generation Type 93AX Coaxial Seal

On June 17, 2025, John Crane unveiled its latest innovation, the Type 93AX Coaxial Separation Seal, a cutting-edge solution aimed at transforming operational efficiency across the energy and process industries. As a leader in rotating equipment solutions and a business unit of Smiths Group plc, John Crane demonstrates its commitment to addressing the pressing challenges faced by sectors such as oil and gas, power generation, and clean energy.

Key Features of the Type 93AX Seal

The Type 93AX is engineered with a robust, fail-safe design that maintains operational integrity even under various failure scenarios. Regardless of the challenges, such as separation gas loss or dry gas seal failure, the Type 93AX adapts seamlessly, ensuring reliable performance. Test results suggest that this innovative seal can significantly lower nitrogen consumption by up to 80% compared to traditional radial separation seals, marking a substantial leap towards enhanced efficiency and sustainability in industrial operations.

Addressing Industry Pain Points

In an industry often plagued by unscheduled downtime—costing an estimated $50 billion annually due to failures—John Crane’s Type 93AX takes proactive measures against significant failure causes like contamination. This seal is specifically designed to prevent oil ingress from the compressor bearing chamber, minimizing risks and supporting a continuous operational flow. Given that equipment failures account for about 42% of unexpected downtimes, the Type 93AX aims to mitigate both performance risks and financial burdens on facilities, potentially saving up to $42 million per facility each year.

Operating Scenarios for Resilience

The Type 93AX boasts three distinct operating scenarios:
1. Standard Operation: Non-contacting mode prevents oil ingress.
2. Separation Gas Loss: Sustains non-contact operation even in the absence of separation gas.
3. Dry Gas Seal Failure: Controls process gas leakage during compressor shutdown, maintaining seal integrity under extreme pressure conditions.

This versatility not only aids in managing disruptions but also enhances the overall reliability of the sealing system.

Commitment to Sustainability and Energy Efficiency

With the global push for sustainable practices, the Type 93AX aligns with essential environmental goals by markedly reducing emissions and energy consumption. The significant drop in nitrogen usage translates into lower operational costs, contributing to sustainability objectives on a larger scale. According to the International Energy Agency (IEA), improving industrial efficiency is projected to reduce global energy use by 12% by 2040, further highlighting the importance of innovations like the Type 93AX.

Mike Eason, Chief Technology Officer at John Crane, emphasized that “Our customers told us they wanted a separation seal that increases safety, efficiency, and reliability. The Type 93AX delivers on these priorities.” This new product enhances not just the asset safety but also ensures reduced environmental impact while offering cost-effective operations.

Global Availability and Support

The Type 93AX can be seamlessly integrated into John Crane's existing dry gas seal portfolio and comes backed by a global network of over 200 facilities, providing manufacturing, sales, and service support in more than 50 countries. This product can be offered as part of a comprehensive solution for compressor upgrades or as a standalone option tailored to specific customer needs.

In conclusion, John Crane's Type 93AX Coaxial Seal is poised to redefine operational standards across the energy and process sectors, offering unparalleled reliability, efficiency, and sustainability. This innovation not only reflects John Crane's commitment to solving industry challenges but also gears clients towards a more sustainable and economically viable future.
