Section III. TECHNICAL PRINCIPLES OF OPERATION
1-15. Functional Description of Pump Unit. The pump unit (Figure 1-2) is a frame mounted 125 GPM pumping
assembly. It consists of a 4-stroke, single-cylinder, air-cooled diesel engine and a direct coupled self-priming
centrifugal pump. A 1-gallon (3.785 I) fuel tank is an integral part of the pump unit. Engine starting is by a safety
starting handle and compression release.
1-16. Principles of Operation. The operation of the centrifugal pump depends on centrifugal force to move water
through the pump and to maintain the desired pressure. The functional description of controls and indicators of
the pump unit are described in Section I of Chapter 2.
