How do water pumps produce smooth, steady streams of water if the pump is moving up and down?

My understanding may be wrong, but I’m fairly sure I’ve seen water pumps moving up and down or back and forth. Wouldn’t that produce little bursts of water? How does it get so smooth and consistent?

In the case of a piston pump pumping from a body of water like a lake or a well, there is a valve that prevents water from going back in your line and there is no air inside so the pump is not only pushing water but also pulling the water behind the pump. If you were to pump from a hand pump you would notice the different flow speeds but on electrical pumps, it is too fast to notice but there will always be variation in the flow.
