SC Hydraulic Engineering GB Series Gas Booster Single Stage
SC Hydraulic Engineering is a leading manufacturer and designer of an ever growing line of high pressure, air-driven liquid pumps, as well as air and gas boosters which are being used in a variety of industries and applications.
Growing since 1953, we offer liquid pressures as high as 65,000 psig and can exceed 17,000 psig in gas pressures.
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.
GB Series Gas Booster Single Stage – Single Acting
Product Information
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.

(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).
