USUN GBD40-OL Booster Pump: The Blending Station Workhorse
Blending your own gas opens up a whole new level of diving, but you need the right tools to do it safely and efficiently. The USUN GBD40-OL Booster Pump acts as the heavy lifter for your fill station. Whether you are topping off oxygen for decompression bottles, mixing helium for deep exploration, or boosting argon, this unit handles the job with reliability. It is specifically designed as a Double Action booster, meaning it moves gas on both the push and the pull of the stroke. This efficiency makes it the perfect choice for filling large-volume cylinders like twinsets (doubles) or multiple stage bottles without spending all day at the blending stick.
Safety and Simplicity
Safety in the gas room is non-negotiable. Because this booster is air-driven, it requires no electrical connection, effectively removing heat, flame, or spark risks from the equation. It arrives oxygen cleaned, so you can start working with pure O2 right out of the box. The unit allows for infinitely variable cycling speed and output, giving you complete control over the fill process.
Built for the Long Haul
Maintenance shouldn't be a constant headache. USUN designed the seal system for a long working life without the need for airline lubrication. This keeps your gas path clean and reduces the time you spend tinkering with the pump. It handles continuous stop-and-start applications without any adverse effects, so you can pause to check your mix or swap tanks without worrying about the equipment.
Power and Pressure
This booster operates with a 40:1 pressure ratio. It requires a minimum inlet pressure of 25 bar (approx. 362 psi) and can deliver a maximum outlet pressure of 332 bar (approx. 4,815 psi).
Drive Gas Requirements
You can power this unit using compressed gas from scuba cylinders or a shop compressor. While the manufacturer recommends 28 cfm to run the booster at a rapid 60-70 cycles per minute, we find that speed excessive for safety-conscious blending. Many of our clients operate this booster successfully with compressors delivering 10 cfm to 14 cfm, resulting in a slower, more controlled fill rate that generates less heat. Note: We highly recommend plumbing a dryer and filter between your shop compressor and the booster to protect the drive mechanism.
