In a major step toward improving sustainability in the energy sector, John Crane has achieved an impressive 99.8% reduction in water consumption at a liquefied natural gas (LNG) export facility in Louisiana, USA.
💡 The Innovation Behind the Breakthrough
The achievement was made possible through the deployment of advanced Type SB2 USP dual-cartridge mechanical seals in high-temperature pump operations.
These seals replaced traditional systems that relied heavily on continuous water usage for cooling and lubrication.
🚰 From High Water Use to Minimal Consumption
Before the upgrade:
- Pumps used around 2,000 gallons of water per day
After installing the new system:
- Water usage dropped to just 3–4 gallons per day
👉 That’s a massive 99.8% reduction, delivering both environmental and cost benefits.
⚙️ How the Technology Works
Traditional systems required a constant flow of treated water to maintain seal performance.
In contrast, John Crane’s solution uses:
- Non-contacting seal technology
- Buffer fluid instead of continuous water flushing
- Reliable operation at high temperatures (180°C–200°C)
This significantly reduces dependency on external water sources while maintaining performance.
🌍 Why This Matters
This innovation highlights how engineering improvements can drive sustainability in industrial operations.
Key benefits include:
- Reduced water consumption
- Lower operating costs
- Improved equipment reliability
- Support for environmental goals
🚀 Fast Implementation, Immediate Results
The system was delivered and installed in just 8 weeks, with:
- No major implementation challenges
- Immediate and measurable results
Following its success, the facility is now considering expanding this technology across other operations.
📌 The Bigger Picture
As industries move toward net-zero and resource efficiency goals, solutions like this demonstrate that:
👉 Small component upgrades (like seals) can create massive sustainability impact
