Liquid CO2 Pump For Supercritical Extraction

Liquid 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

Liquid carbon dioxide booster pump and pressurization equipment, commonly used in carbon dioxide supercritical extraction of various plant extracts, material foaming, and carbon dioxide fire extinguisher filling. Among them, carbon dioxide extraction is often used in biopharmaceuticals. Experimental research works by using a special pump for liquid carbon dioxide to pressurize carbon dioxide to a supercritical state, which is used to decompose various elements in plants for easy extraction.
