manual pump
Human-powered fluid pusher
A manual pump is a device for moving liquids or air that operates by human power rather than electricity or engine.
The user typically works a handle, lever, or plunger to create pressure: The well had an old manual pump in the yard.
Common examples include hand-operated water pumps, bicycle tire pumps, and breast pumps designed for use without batteries.
