INTRODUCTION
Overview
The Fire Research PumpBoss pressure governor uses state of the art programmable
microprocessor technology and operates in one of two modes, pressure or RPM. It
will maintain a steady pump discharge pressure within system capabilities by controlling
the engine speed. When selected, it will also maintain a selected engine RPM.
In pressure mode the PumpBoss 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 PumpBoss maintains a constant engine RPM. The pump
discharge pressure is monitored, it can vary but will be limited to an increase of 30 PSI.
If the discharge pressure increases 30 PSI, the pressure governor will automatically
lower the engine RPM to reduce the discharge pressure.
All controls and indicators are located on the front of the control module.
