2OverviewTo control pump operations the 2013 Rosenbauer Rear Mount Pumpers are equipped with a Pump Boss 400 pressure governor.The Pump Boss 400 pressure governor operates in one of two modes; pressure or RPM.It maintains a steady pump discharge pressure within system capabilities by controlling the engine speed or holds a selected engine RPM.
3Features Automatic regulation of pump discharge pressure Large Control Knob - Easy to operate with a gloved handDual 600 PSI discharge and intake mounted pressure sensorsProgrammable preset settingsAlways starts in Pressure Mode at Idle RPMDisplays and LEDs automatically adjusted for day or night operation
4Features Limits increase of pressure when in RPM Mode Recognition of No Water Condition with automatic responseNo pressure or RPM variation when changing modesRed IDLE Button - Brings the engine to idle RPM quicklyManual control of pressure or engine RPM settingsRetains warning alerts historyAudible alarm buzzer

7How does it work?In Pressure Mode, the governor maintains a constant pump discharge pressure. The discharge pressure is monitored and compared to the selected pressure setting, the engine RPM is varied to keep the discharge pressure at the selected setting.In RPM mode the governor maintains a constant engine RPM. The pump discharge pressure is monitored, it can vary but is limited to an increase of 30 PSI. If the discharge pressure increases 30 PSI, the pressure governor automatically lowers the engine RPM to reduce the discharge pressure.
