ABSTRACT:
A pneumatically driven pump includes a piston threadably connected to each end of a common connecting hollow rod which is inserted over a pumped material receiving tube, with this assembly enclosed in a housing. The pistons reciprocate in response to compressed air sequentially directed through different air ports in the housing, alternatively drawing in pumped material and then pumping it out of the pump through the pumped material tube along the center of the pump. A check valve at each of the inflow and outflow ends of the pump prevents back flow of the pumped material.
