Abstract:
1. A Mobile pump system comprising: an engine; a reserve tank having an inlet opening, an outlet opening, and a level sensor; a primary pump driven by said engine, the primary pump including a supply side and a discharge side; an intake manifold having two inlets and two outlets; a first conduit for joining one of the inlets of the intake manifold in fluid communication with a source of pressurized liquid, a second conduit for joining one of the outlets of the intake manifold to the inlet opening of the reserve tank; a third conduit for joining the other inlet of the intake manifold to the outlet opening of the reserve tank; a supply line for joining the other outlet of the intake manifold to the supply side of the pump; a first control valve associated with the first conduit, the first control valve having a closed position preventing flow from the source of the pressurized liquid into the intake manifold and an open position allowing flow into the intake manifold; a second control valve associated with the second conduit, the second control valve having a closed position preventing flow from the intake manifold into the reserve tank and an open position allowing flow from the intake manifold into the reserve tank; a third control valve associated with the third conduit, the third control valve having a closed position preventing flow from the reserve tank into the intake manifold and an open position allowing flow from the reserve tank into the intake manifold; an inlet pressure sensor communicating with the intake manifold and monitoring the pressure P a priming pump associated with the primary pump; a discharge manifold having an inlet opening coupled to the discharge side of the primary pump and a plurality of outlet openings coupled to discharge hoses; a fourth control valve located between the primary pump and the discharge manifold, the fourth control valve having a closed position preventing flow from the primary pump into the discharge manifold and an open position allowing flow from the primary pump into the discharge manifold; a fifth control valve disposed between the discharge manifold and a discharge outlet; a flow meter disposed in a conduit leading to the discharge outlet; a discharge pressure sensor communicating with the discharge manifold and monitoring the pressure P a master processor receiving input from the level sensor, the intake pressure sensor, and the discharge pressure sensor, and being programmed to:
