A liquid pump comprises generally a base, an annular ring including a pair of ingresses and a pair of egresses alternately formed on opposing circumferential walls aside a pair of rectangular recesses therebetween and defining a fluid channel between the base and itself, first and second swivel disks including a rotary plunger and a pushing rod on their under sides and rotating inversely inside the pump. An elongate slider sliding to and fro in a rectangular groove coactes with the rotary plunger for repeatedly changing the vacuum circumstances in the channel to synchronously suck and discharge the liquid material from one container to another.
