USUN GB40-OL Booster Pump: Efficient Gas Management for Tech Divers
Every technical diver knows the frustration of having plenty of oxygen or helium left in a storage cylinder, but not enough pressure to get a good fill for a deco bottle or rebreather tank. The USUN GB40-OL Booster Pump solves this problem, allowing you to pull that expensive gas down low and boost it to the pressure you need. This unit creates a cost-effective solution for managing your gas logistics safely and efficiently.
Ideal for Smaller Cylinders
This is a Single Action booster, designed specifically for precision and smaller volumes. While it is capable of filling up to an AL80 (11.1 liters), it truly shines when filling cylinders smaller than 40 cubic feet (approx. 5.7 liters). This makes it the perfect workhorse for topping off rebreather oxygen and diluent tanks, or filling shallow decompression bottles without wasting gas.
Safety First
Working with high-pressure oxygen requires strict safety protocols. This booster arrives oxygen cleaned and ready for service. Because it is air-driven, it requires zero electrical connections. This eliminates the risk of heat, flames, or sparks during operation, giving you peace of mind when blending volatile mixes.
Low Maintenance, Long Life
You want to spend time diving, not servicing your pump. The USUN seal system is designed for a long working life and requires no airline lubrication. This keeps your gas path clean and reduces maintenance downtime. The unit is robust enough to handle continuous stop-and-start applications, so you can check pressures and switch tanks without worrying about the booster stalling or overheating.
Drive Gas Requirements
You can power this booster using a shop compressor or compressed gas from scuba cylinders. While the manufacturer lists a high requirement of 28 cfm for rapid cycling, we prioritize safety and heat management. Our clients successfully run this booster with compressors delivering 6 to 10 cfm, resulting in a slower, cooler, and safer fill rate.
- Pro Tip: In our experience, using one standard AL80 cylinder to drive the booster will typically boost about 40 cubic feet of gas. Keep in mind that your results may vary depending on your starting and ending pressures.
System Customization
Please note that this booster ships without hoses or fittings. However, we are here to help. If you need assistance building a complete system with the correct whips, gauges, and connections for your specific setup, just reach out to us.
