Abstract
A fire fighting vehicle includes a chassis, an engine coupled to the chassis, a fluid tank configured to store a fluid, a fluid delivery system, and a controller. The fluid delivery system includes a first pump, a second pump, a low pressure discharge, a first high pressure discharge, and a second high pressure discharge. The first pump is coupled to the fluid tank and configured to pump the fluid therefrom at a first pressure. The second pump is positioned downstream of and coupled to the first pump in a serial arrangement. The controller is configured to selectively vary at least one of a speed, a power output, and a torque output of the engine and thereby provide the fluid to at least one of the first high pressure discharge and the second high pressure discharge at a target discharge pressure.
