Power unit GBD series

A reciprocating, positive displacement gas pump with a directly coupled, integral linear reciprocating air motor. As a Standard Gas Power Unit (GPU), it responds to customers’ needs for pre-engineered and user-friendly Gas Booster systems. 2-Stage Double Acting Gas Booster Power Unit Hydratron 2-Stage Double Acting Air Driven Gas Booster is a reciprocating, positive displacement gas pump with a directly coupled, integral linear reciprocating air motor, designed to generate High-Pressure Gas output. With double-acting models, the pressure increase is made possible by means of the area ratio between the larger diameter air drive piston directly connected to two smaller diameter gas pistons having differing diameters to each other. The reciprocating action of the gas booster draws gas at low pressure into the booster then displaces the gas at a higher pressure output from the booster into a closed system.On 2-Stage Double Acting models, the inlet gas pressure is used to provide pressures, higher output pressures and higher flowrates to be achieved. When using a 2-Stage Double Acting Gas Booster, care must be taken to ensure that the outlet pressure remains lower than the maximum supply pressure multiplied by the combined area ratio of the 2 Gas pistons since this can cause “interstage stall”. To avoid this the inlet gas pressure can simply be reduced.The Two-Stage Double Acting Gas Booster Power Unit can be provided as a pump only system.
