Compressed Air Driven Gas Booster Pump- DGA/DGD/DGT SeriesCompressed Air Driven Liquid Gas Booster Pump-DGG/DGGD/2DGGD Series

SUNCENTER 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 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.

Key features include: Applications

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
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

2DGGD Series Liquid Gas Pumps(Double acting, Double air drive heads)

They are characterized by the same features as the DGGD pumps double acting, but with two air driven

head types, they have less pulsations and deliver approx. 100 % more flow.
