Haskel Gas Booster Pumps Model AGT

Two Stage Model 'AGT' boosters provide efficient means of boosting to a high compression ratio since the ratio per stage is low. Maximum outlet pressure with these models is drive area ratio times air pressure PLUS supply pressure times area ratio of the two gas pistons. Since these models have interconnected gas pistons, they multiply supply pressure during the 'interstage' stroke by the area ratio of the two gas pistons. If supply pressure is too high, the booster may have 'interstage stall' at an outlet pressure substantially less than that obtainable on the 'output' stroke. The selection that shows the maximum supply pressure as a factor times Air drive pressure. This limitation does not apply if outlet pressure is less than the 'maximum supply' times the area ratio of the two gas pistons.

The selection of the proper Gas Booster for any application starts with determining which booster “series” will provide the amount of flow required. This can be determined by the chart information provided in the Overview Tab. The possible ratios for the application are determined by examination of the performance data for the booster using the air pressure and air flow available. The ability of the booster to generate pressure is a function of the drive pressure, the nominal ratio, and the maximum compression ratio. The ability to generate flow is a function of the quantity of air available to drive it, the displacement per cycle of the pump, and the volumetric efficiency. Within each booster series, there are standard materials of construction available. For applications involving aggressive gases, some material substitutions may be possible.
