Usunair driven gas boosterpumpsare ratio devices that utilize low pressure compressed
airdriving a larger diameter piston (area x pressure) which is linearly connected to a smaller
hydraulicpiston/plunger. Using this ratio principal, a higher hydraulic pressure can be generated.
UsunPump model numbers reflect the pumps nominal pressure ratio, while the technical data
indicates exact ratios.The outlet stall pressure is easy to set by adjusting the air drive pressure
through a simple air pressure regulator. By multiplying the pressure ratio by the available shop
airpressure, the nominal gas pressure can be calculated.
Example ( Pump Model:GB25 Gas boosterpump)
Air drive piston area (GPS 16Assembly Line & Production Line 0mm Ø)
Hydraulic plunger area (32mm Ø)
Actual ratio =25:1
LED Module 1. AIR DRIVE SECTION
The air drive section consists of a light weight piston complete with seals running inside an
aluminumbarrel. The diameter of the air piston is160mm. When compressed air is supplied to
the pump the airpushes the air piston down on a compression stroke
(forces as out of the gas end).
Under thecontrol of pilot pins (poppet valve) triggered at each end of the stroke

The next question is wheather you want the booster to stall when an outlet pressure is reached
If so ,a simple airline pressure regulator will suffice ,but remember the flow drops off dramatically as the
booster reaches a stall condition .

Remark 1) Maxium outlet pressure are at an air driven pressure of 8 bar or 116 PSI ,for long life using
of such pump ,we suggest that air driven pressure should be not more than 8 Bar.Typical application of such air driven refrigerant pump
