China Oxygen Gas Booster Gas Pressure Booster Gas Booster

USUN Model :GB40-OL 160MM drivendiving or scuba air driven oxygen gaspressure booster Pump

Example ( Pump Model:GB25 Gas boosterpump)

Air drive piston area (160mm Ø)

Hydraulic plunger area (32mm Ø)

Actual ratio =25:1

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

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 oxygen gas booster pumpFactory real pictures
