GBD Series Gas Booster Single Stage - Double Acting

Product Features and Specifications

  • General Product Information
    • schydraulic-gbdgasbooster
      REQUIRES NO LUBRICATION
      HIGH FLOW, MEDIUM PRESSURE
      REMOTE CONTROL CAPABILITIES
      OIL-FREE HIGH PRESSURE SECTION
      NOMINAL PRESSURES UP TO 12,500-PSI
      AIR OPERATED DOES NOT REQUIRE ELECTRICITY

      This series of boosters doubles the volume of output gas per cycle and is a good choice for moving relatively high volumes at pressures up to 20,000 psig. Supply pressure is added to the maximum outlet pressure.

      The GBD-5 gas booster is a modified version of our popular ABD air booster. It is used to boost gas pressures up to 1,500 psig. The booster is able to move large volumes of gas efficiently when lower pressures are suitable.

      Refer to corresponding gas booster performance curve for operating pressures. Maximum material rated outlet pressures can be reached under special operating conditions. Do not use air drive and/or gas supply pressures that equate to higher outlet pressures than those "maximum material rated outlet pressures" shown on table. Refer to Static Outlet Stall Pressure formula shown on table (for example, for gas booster model GBD-30 the formula is: Static Outlet Stall Pressure = 30*Pa+Ps). Maximum recommended air drive operating pressure: 100-psi. Maximum rated air drive pressure: 150-psi (only for static outlet stall pressure).

      (1) Coned and threaded high pressure connection for 1/4" O.D. tubing.

      (2) Limit maximum gas supply pressure by formula Ps max = factor * Pa to avoid interstage stall

      (for example, for gas booster model GBT-15/30 the formula is: Ps max = 15*Pa).

      Refer to corresponding gas booster performance curve for operating pressures. Maximum material rated outlet pressures can be reached under special operating conditions. Do not use air drive and/or gas supply pressures that equate to higher outlet pressures than those "maximum material rated outlet pressures" shown on table. Refer to Static Outlet Stall Pressure formula shown on table (for example, for gas booster model GBD-30 the formula is: Static Outlet Stall Pressure = 30*Pa+Ps). Maximum recommended air drive operating pressure: 100-psi. Maximum rated air drive pressure: 150-psi (only for static outlet stall pressure).
