The PumpBoss 400 pressure governor uses state-of-the-art programmable microprocessor technology and 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.
While the PumpBoss is not, the latest series PumpBoss 400 can monitor both the pump intake and discharge pressure providing improved defense against pump cavitations.
The PumpBoss 400 governor has a 4-digit LED display for engine RPM, four LED bar graphs that provide a constant display of the engine oil pressure, engine coolant temperature, transmission temperature, and battery voltage.
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.
