Fire Research Corp. PRA310-D00 pressure governor
Maintains a steady pump discharge pressure by controlling engine speed or holds a selected engine RPM
Offers complete engine control and remote display in a single, compact unit
Operates in one of two modes, pressure or RPM
In pressure mode it maintains constant pump discharge pressure, it is monitored, compared to the selected pressure setting, and the engine RPM is varied to keep the discharge pressure at the selected setting
In RPM mode it maintains constant engine RPM, the pump discharge pressure is monitored and can vary, but as a safety feature, it is limited to an increase of 30 PSI
If the discharge pressure increases 30 PSI the governor automatically lowers the engine RPM to prevent a pressure surge
All controls and indicators are located on the front of the control module
