the electrical mini pump is specially for the Gprokeg plastic kegs, including reusable kegs and plastic ecokegs, as pressure source.

with pressure control unit, the electrical pump work automatically at the pressure of 3bar ~ 4bar (43.5psi ~ 58psi), and with pressure regulator to provide the best working pressure for the kegs, to keep safe, stable and best working pressure for the kegs for better dispensing performance.

only air need to be pumped into the space between the keg and the inner beer bag, no special inert gas (food grade pure CO2, etc.) will be needed, the most cost effective, low carbon and most green solution for the kegs dispensing.

the pumped air never goes into and contact with the beer in the Gprokeg plastic kegs, the beer in the kegs will never be contaminated by the gas (air, CO2, etc.), thanks to the multi barrier technology, the beer in opened Gprokeg plastic kegs still can be kept for over one month.
