An automatic pump is provided to cut down a cost by allowing a valve guide to be separated from a discharge pipe to replace a valve. In an automatic pump, an inlet pipe and a discharge pipe are formed at a body(110) integrally. A valve seat(150) and a valve guide(160) are installed apart from each other inside the discharge pipe. Both sides of a valve(140) are supported to the valve seat and the valve guide and linearly moved to connect and disconnect an inlet pipe side and a discharge pipe side. The valve and the valve guide are provided with a unit for indicating a combining position of the valve and preventing rotation of the valve.
