Compressed Air Driven Gas Booster Pump- DGA/DGD/DGT Series

Suncenter Air Driven Gas Boosters provide for pressures up to 80Mpa (11,600 psi). Used for virtually all known gases, these boosters are ideal for increasing gas pressure, transferring high pressure gas, charging cylinders and scavenging. Key features include: 

Compressed Air driven - no electricity required (connect to normal air compressor)
In order to extend the lifetime of the pump, the driving air pressure should 
not be higher than 8 bar
No airline lubricator required 
Hydrocarbon free - separation between air and gas sections 
Pressures to 80Mpa (11,600 psi)  
Wide range of models with different ratios
Built-in-cooling on most models 
Easy to install, operate and maintain
Best price / performance ratio 
No heat, flame or spark risk and explosion proof 
Automatic pressure holding, whatever the cause of the pressure drop, the Suncenter   pump will automatically start, keep the loop pressure constant
Applicable gas:Air/Ar(Argon)/He(Helium)/H2(Hydrogen)/O2(Oxygen)N2(Nitrogen)
CO2/NO2/CH4/C2H2/LNG/LPG/CNG/FM200/SF6/H2S etc

Applications for Air Driven Gas Boosters

SUNCENTER Air Driven Gas Boosters provide for pressures up to 80Mpa. Used for oil free compression not only of air or Nitrogen, but also flammable and risk gases like hydrogen, oxygen and natural gas. These boosters are ideal for increasing gas pressure, transferring high pressure gas, charging cylinders and scavenging.

Air driven boosters are an efficient alternative instead of electrically driven products and can be used in explosion- proof areas.

As a result of the wide range of models it is possible to select the optimum booster for each application. Single stage, double acting or two stage boosters or a combination of these models can be used to achieve different operating pressures and flow capacities.

SUNCENTER Air Driven Gas Boosters are ideal and widely used for hydrostatic and burst testing for valves, pipes, tubing and pressure vessels; Calibration for safety valves; Automobile regulator detecting and telecommunication cable inflatable appliances.

Applications 

Pressure test with gas/air
Gas transfer and filling
(Air/Argon/Helium/Hydrogen/Oxygen/Nitrogen/CO2/NO2/CH4/LNG/LPG/CNG/FM200 etc.)
Charging of gas cylinder and accumulator with nitrogen
Nitrogen gas spring charging
Supply for isolating gas systems
Gas assisted injection molding
Transfer of oxygen cylinders
Charging of breathing air bottles
Leak test 
Hydrostatic Testing for valves, tanks, pressure vessels, pressure switches, hoses, pipes and tubing, pressure gauges, cylinders, transducers, well casings, BOPs, gas bottles and air craft components
Safety valve adjusting
