ABSTRACT:
An improved pump for pumping both low viscosity and high viscosity fluids, which contains therein a body with three cavities, a hollow cylinder fitting in the first cavity and attached at its lower end, a hollow cylinder head containing therein a first valve means; having in the second cavity of said body of said pump a second valve means with a shaft positioned at the top end of said hollow cylinder such that said first valve means and said second valve means are positioned to ride freely on said shaft. Finally, a kick plate means positioned at the end of said shaft and located such that it can move freely within said third cavity means. When the pump is pumping high viscosity fluids it is the function of the kick plate means to push or force the high viscosity fluid up from said third cavity into the second cavity and then through the hollow cylinder head into the first cavity means and out through the outlet means in said pump. The kick plate means does not affect the efficiency of the pump when it is pumping low viscosity fluids.
