In essence  the term piggyback is when your using multiple pumps that are assembled or combine on one drive shaft. And the pump numbers listed above are usual for these pumps. Usually you will have a smaller section in the front and middle with the larger one in the back. You have different reservoirs and different fluids pumped into a piggyback system, with no worry of mixing fluids.

And the way the piggybacks are made will deliver greater outputs and efficiency. The most common uses of piggybacks are on utility vechiles, front end loaders and shovel loaders.
