Abstract: A pumping-out apparatus provided herein is configured such that a follow plate is placed on a fluid surface of a stored fluid in a container, a suction port of a pump is attached to an attachment hole of the plate, and the stored fluid is pumped out by the pump. The pumping-out apparatus includes: the pump; a post on which the pump is fixedly provided; a lifted and lowered base on which the container is mounted and which is provided so as to be able to be lifted and lowered along the post; a tension spring configured to hang the lifted and lowered base and bias the lifted and lowered base in an upward direction to cause the fluid surface of the stored fluid in the container to press the plate; and a lifting and lowering operation portion configured to lift and lower an upper end portion of the spring.

Abstract: To simplify a pumping-out operation, prevent a follow plate from being contaminated by leakage of a fluid from a contact portion between the follow plate and a container, and reduce the size of a pumping-out apparatus.
