Section III. TECHNICAL PRINCIPLES OF OPERATION I
1-10 Principles of Operation. Once the suction and discharge valves are opened and engine started, the pump draws
water from large storage source or upline boost pump It sends the water to distribution points or another pumping
assembly serving as an upline boost pump.
In automatic operation, a pressure control module responds to suction and discharge pressures. If an interruption of water
flow occurs, the pressure control module automatically brings the engine speed to idle.
The functional description of controls and indicators of the pumping assembly are described in Section I of Chapter 2.
