This document discusses the development of a new tractor unit with a centrifugal pump that can be used as a portable blender to mix liquid additives. It describes some of the key features of the unit, including its 6-inch manifold, mag meter, suction hoses, and battery backup system. The unit was tested by Alvarado and able to achieve blending rates of 81 bpm at 50 psi.
