A hand operated air pump apparatus comprising an internal bellows in communication with an outer bellows wherein variable force on air pump forces compressed air through a discharge valve into a annulus between a bottle and a flexible bladder wherein said pump is attached upon a container or bottle like vessel wherein pumping action forces from bottle highly viscous substances, that may contain solid or abrasive particles, through a discharge spout without internal substance being contaminated by air or other environmental factors thus allowing for an improved method of removing all contents within a container with greater ease.
