A siphon pump is a simple device used to move liquids from one container to another without the need for a mechanical pump. It works by creating a difference in pressure, allowing gravity to pull the liquid through a tube. The process typically starts by filling the tube with the liquid and then lowering one end into the receiving container, enabling the liquid to flow. Siphon pumps are commonly used in various applications, such as transferring fuel from a tank, draining aquariums, or moving water in gardening. They are easy to use and require minimal equipment, making them a popular choice for both household and industrial tasks.
