SC Hydraulic Engineering works internationally through distribution and with manufacturers. We are continually developing new products to meet a never-ending stream of newly emerging applications and will continue to meet tougher, more demanding requirements.

SC Hydraulic Engineering GB Series Gas Booster Single Stage

Product Information

  • Low Flow, Low Pressure
  • Requires No Lubrication
  • Remote Control Capabilities
  • Oil-free High Pressure Section
  • Nominal Pressures Up To 7,500-psi
  • Air Operated – Does Not Require Electricity

The GB series is the most economical of the SC Hydraulic Gas Boosters and is ideal for applications not requiring much volume such as pressure testing small vessels or components. Pressures can be boosted from as low as 50 psig and up to over 11,000 psig.

SC Hydraulic Engineering GB Series Application

  • Leak Detection
  • Pressure Testing Vessels
  • Low Pressure Gas Recovery
  • Charging Of Nitrogen Bottles
  • Gas Assisted Injection Molding
  • Aircraft Slide Chute Gas Storage
  • Charging Of Nitrogen Accumulators
  • Transfer Of Sf6 For Arc Suppression
  • Transfer Of Sf6 For Circuit Breaker Insulation
  • Boosting Pressure From Nitrogen Generators

  1. Coned and threaded high pressure connection for 1/4″ O.D. tubing.
  2. Maximum allowed working pressure for oxygen service boosters: 5,000-psi max.
  3. Maximum allowed working pressure for hydrogen service boosters : 6,000-psi max.
  4. Oxygen & hydrogen service boosters not available on all models. Contact factory for more information.

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).
