ABSTRACT:
A fluid pump for transferring liquid material from one container to another is provided. The fluid pump is of a novel structure which comprises a circular base having a less diameter annular projection at a central portion and first guide slot radially formed through the body, an external annulus having a pair of second guide slots made in registry with the first guide slot to define a rectangular space therebetween for facilitating a slider to slide thereabout; a rotary disk disposed into the annulus including a plunger and pushing rod at under side for synchroneously sliding in a fluid channel and actuating the slider to move about so as to repeatedly alter the vacuum state in the pump for sucking the liquid material from one container and simultaneously discharging the sucked liquid material to another container.
