PUMP BOSS w/ Dual Sensors

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 new, 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. The PumpBoss has a message display that shows the pressure or RPM setting during normal operations and fault warning alarms as they occur. When selected by the operator it will show monitored information, stored data, and program options.

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.

Ford 6.7L Diesel Interface Information

J1939 CAN inputs are required to provide engine information to the governor. To do this a Ford vehicle CAN Bus to J1939 Translator Module must be installed.

    There are two scenarios:
  • The J1939 Translator Module comes installed as part of the NFPA1901 compliant FRC Seat Belt Monitoring System. The governor J1939 CAN inputs are connected to the connector that is installed as part of the harness.
  • The J1939 Translator Module is installed as a component with governor kit (no FRC Seat Belt Monitoring System is installed). The governor J1939 CAN inputs are connected to the new harness that is installed between the ODB-II connector and the J1939 Translator Module.
