Gas transfer booster pump for N2O/CO2/NOVEC
Compressed Air Driven Liquid Gas Booster Pump-DGG/DGGD Series.
SUN CENTER pumps are air driven at a drive air pressure of 2 to 10bar (29 to145 psi) 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 booster pump will automatically start, keep the loop pressure constant
Applicable for various kinds of gas such as N2O/CO2/NOVEC/Refrigerant etc.
For liquid gas(liquid+gas mixture) cylinder transfer/filling/recovery
For CO2 Fire Extinguisher filling
For Supercritical CO2 extraction

Suncenter DLS Series liquid gas filling booster pump system
SUN CENTER- Liquid gas filling pump systems are compact and delicacy solution tailored to customer specific requirements with air driven pumps as well as all accessories to be fitted and installed on the frame or in a closed cabinet.
To operate this system, the pressure gauges, valves, and pressure regulators have to be fitted on panels. The outlet pressure is easy to be set through a simple air regulator. The pump stops automatically when this end pressure is reached and restarts with a slight drop in the outlet pressure or an increase in the air drive pressure.
As the pressure will be generated by means of a pneumatically operated pump，the electric connection will not be necessary. To operate this system, the air driven pump has to be equipped with the air control unit combined filter, pressure-regulating valve, pressure control gauge as well as manual relieve valve. In this operation, the pump will be mounted to the stainless steel tank in the closed cabinet in a compact and space saving manner. Pressure gauges, valves, and pressure regulators will be fitted on the panel.
