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

Question

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?

Answer 1

Since you say moving up and down,I assume you mean like a piston pump.

It could be a pump that “pumps” on both upstrokes and downstrokes.

It’s called a double displacement pump.
