Abstract
The portable, light-weight pumping mechanism is for transferring and mixing two fluids from a portable fluid container having a top portion of predetermined dimensions and having an inlet port. The portable pumping mechanism is comprised of a base cover member having an aperture therethrough and having a downwardly extending circumferential lip adapted for securing the pumping mechanism to the top of the portable fluid container. A frame structure is mounted to the top of the base cover member and a pair of interconnected elongated pneumatic pumps are mounted to the frame structure. One of the pneumatic pumps is connectable to a compressed air source. A downwardly extending pickup conduit protrudes through the aperture in the base cover member to sealingly engage the inlet portion of the container and it is further in communication with one of the pumps for removing fluid from the portable fluid container. A catalyst inlet portion is in communication with the second pump and an elongated flexible hose assembly which is comprised of two parallel and connected hoses are in communication with the first and second pumps. A mixing and ejecting probe assembly is disposed at the end of the hose assembly for transferring the fluid mixture to a predetermined location for sealing purposes.
