iquid CO2 pump for Supercritical extraction
Air Driven Liquid CO2 Booster Pump-DGG/DGGD Series.
SUN CENTER pumps are air driven at a drive air pressure of 2bar to 8bar by the normal air compressor. Basically, the principle of operation is similar to a reciprocating amplifier where control of the piston at the end position is regulated by a pilot operated 4/2 way valve.
Suncenter pumps feature a large air piston joint to a smaller diameter plunger. The pressure ratio is the difference between these two areas and is the method of determining maximum outlet pressure. Higher pressures obtained by using higher pressure ratios. Suncenter model numbers reflect the pumps nominal pressure ratios， while the technical data indicates exact ratios. The outlet pressure is easy to set through a simple air regulator. By multiplying the pressure ratio by the available shop air pressure, the nominal outlet pressure can be calculated.
Key features include:
Compressed Air is 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
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 for liquid CO2/liquid+gas mixed CO2/Supercritical CO2
For liquid CO2 cylinder transfer/filling
For CO2 Fire Extinguisher filling
For Supercritical CO2 extraction
