AIR OPERATED GAS BOOSTER PUMPS


     
GB144S illustrated   GB186D illustrated



The hydratron range of air operated gas booster pumps are designed to boost bottled gases such as air, nitrogen, helium, hydrogen* or methane* upto higher pressures. They can be used for pressure testing or for pre-charging accumulators and down hole tools. Being air operated they are inherently safe and can be used in fire hazardous areas.

The output pressure and flow generated by these versatile pumps can be infinitely varied by simply adjusting the air drive pressure and flow rate.

* When using a Hydratron gas booster to boost methane or hydrogen, the unit must be sited in a safe and well ventilated area and the threaded vent piped away to a controlled environment.

The above stated flow rates are approximate and assume that a 100 PSI (7 Bar) air supply is avaliable at 56 SCFM (1600 N Ltr/min) for the 'S' models and 120 SCFM (3400 N Ltr/min) for the 'D' models

Models marked with an asterisk are ‘Two Stage’ models, capable of boosting to a higher compression ratio. To achieve this they have inter-connected gas pistons of different diameters which allows them to boost the gas supply by the area ratio of the two pistons and provide the high pressure piston with an interstage pressure. If the outlet pressure for these models is greater than the maximum supply pressure multiplied by the area ratio of the 2 gas pistons, “Interstage stall” may occur. To avoid this, the gas inlet supply pressure would need to be reduced.
