The pump on a keg serves a crucial role in dispensing beer. It is a hand-operated device that acts as the pressure source to force the beer out of the keg and into a glass or container. This pump is commonly used in situations where a pressurized system or a CO2 tank is not available.
When using a pump, it is important to understand that the beer should be consumed within a relatively short period of time, ideally within a few hours. This is because the pump introduces outside air into the keg, which can cause a bacteria reaction that will ultimately spoil the beer within 8-12 hours.
The pump works by creating pressure within the keg, which then pushes the beer through a tube and out of the tap. As the handle of the pump is manually operated, it creates the necessary pressure to overcome the resistance within the keg and dispense the beer.
One key factor to consider when using a pump is maintaining cleanliness and hygiene. It is crucial to ensure that the pump and all associated equipment are thoroughly cleaned before and after each use. This helps to minimize the risk of contamination and maintain the quality of the beer.
Personal experience: I have encountered situations where a hand pump was the only option available for dispensing beer from a keg. It was during a small outdoor gathering where there was no access to a pressurized system or CO2 tank. While the pump served its purpose in allowing us to enjoy the beer, we were cautious about consuming it within a few hours to avoid any potential spoilage.
