Abstract

A firefighting vehicle having a dual pressure pump system includes a fluid supply, a first pump stage coupled to the fluid supply and configured to pump fluid at a first pressure, a second pump stage coupled to the first pump stage and configured to pump fluid at a second pressure, the second pressure being substantially different from the first pressure, a fluid manipulator; and a valving arrangement coupling the first pump stage and the second pump stage to the fluid manipulator, the valving arrangement being selectively adjustable between a first position forming a first fluid path and a second position forming a second fluid path, wherein the first fluid path provides the fluid to the fluid manipulator at a first output pressure and the second fluid path provides fluid to the fluid manipulator at a second output pressure.
