Abstract
An easily adjustable and serviceable plural component pumping system has a frame assembly with a pivotable drive beam. The drive beam passes through spherical rod bearings in the connecting rod of two positive displacement pumps. The pumps are mounted to the frame via hand tightenable clamps so that by loosening the clamp the pumps may be slid along the frame to vary the ratio or remove for servicing without the need for too.
