Air Driven Liquid CO2 Booster Pump-DGG/DGGD Series.
SUNCENTER 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 of 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 easily 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.

◪ 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.
