Using this ratio principal, a higher hydraulic pressure can be generated.UsunPump model numbers reflect the pumps nominal pressure ratio, while the technical dataindicates exact ratios. The outlet stall pressure is easy to set by adjusting the air drive pressurethrough a simple air pressure regulator. By multiplying the pressure ratio by the available shopairpressure, the nominal gas pressure can be calculated.Example ( Pump Model:GB25 Gas boosterpump)Air drive piston area (160mm Ø)Hydraulic plunger area (32mm Ø)Actual ratio =25:11. AIR DRIVE SECTIonThe air drive section consists of a light weight piston complete with seals running inside analuminumbarrel. The diameter of the air piston is160mm. When compressed air is supplied tothe 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 stroke2.
