Abstract
A fire apparatus includes an engine, a fluid delivery system, and a controller. The fluid delivery system includes a first pump that provides a first fluid output at a first pressure, and a second pump positioned downstream of and coupled to the first pump in a serial arrangement. The second pump is driven by the engine. The second pump provides a second fluid output at a second pressure. During a first mode, the first fluid output is dischargeable from a low pressure discharge. During a second mode, the second fluid output is dischargeable from a first high pressure discharge and/or a second high pressure discharge, the engine operates at a first set point when the second fluid output is discharged from the first high pressure discharge, and the engine operates at a second set point when the second fluid output is discharged from the second high pressure discharge.
