The PRO-T pressure governor and all-in-one instrument panel use state-of-the-art, programmable, microprocessor technology. It maintains a steady pump discharge pressure by controlling engine speed or holds a selected engine RPM. It offers complete engine control and remote display in a single, compact unit.
The governor operates in one of two modes, pressure or RPM. In pressure mode it maintains constant pump discharge pressure. The discharge pressure 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.
