Abstract
A vibrating column pump pumps liquid by making use of liquid vibration generated at the time when the vibrating pipe is vibrated in a longitudinal direction thereof. The vibrating column pump comprises a vibrating pipe for pumping liquid therethrough, flexible pipes for connecting both ends of the vibrating pipe with a stationary suction pipe and a stationary outlet pipe, vibrating means for vibrating the vibrating pipe in a longitudinal direction thereof, and retainer means for removably retaining the vibrating pipe in such a manner that the vibrating pipe is removably connected to the vibrating means. The liquid contacting unit including the vibrating pipe and the flexible pipes is separated from the vibrating means so that the liquid contacting unit is disposable and can be easily replaced with a new one.
