Fire Research Pump Boss 400 Pressure Governor
Overview To 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.
Features Automatic regulation of pump discharge pressure Large Control Knob - Easy to operate with a gloved hand Dual 600 PSI discharge and intake mounted pressure sensors Programmable preset settings Always starts in Pressure Mode at Idle RPM Displays and LEDs automatically adjusted for day or night operation
Features Limits increase of pressure when in RPM Mode Recognition of No Water Condition with automatic response No pressure or RPM variation when changing modes Red IDLE Button - Brings the engine to idle RPM quickly Manual control of pressure or engine RPM settings Retains warning alerts history Audible alarm buzzer
Information Provided by Pump Boss Engine RPM; shown with four daylight bright LED digits Check Engine and Stop Engine warning LEDs Engine oil pressure; shown on a dual color (green/red) LED bar graph display Engine coolant temperature; shown on a dual color (green/red) LED bar graph display Transmission temperature: shown on a dual color (green/red) LED bar graph display Battery voltage; shown on a dual color (green/red) LED bar graph display Pressure and RPM operating mode LEDs Pressure/RPM setting; shown on a dot matrix message display Throttle ready LED.

Diagnostic and Warning Messages High Battery Voltage Low Battery Voltage (Engine off) Low Battery Voltage (Engine running) High Transmission Temperature Low Engine Oil Pressure High Engine Coolant Temperature Out of Water (Visual alarm only) No Engine Response (Visual alarm only).
How 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.
Henderson Fire Department Presets The preset button on the Pump Boss has been preprogrammed by our department to 145 PSI to aid in quick setup for standard 200’ 1.75” hose speedlay deployment.
