Session 3 Practical Pump Operations
SPO 3-1 The student will demonstrate an understanding of the operation of a centrifugal fire pump to supply and apply water from various sources, in various capacities, and in various operations, through practical activities, to the satisfaction of the instructor, and satisfactory completion of required skills.
3 - 1 Demonstrate an understanding of pump operations for supplying water from pressurized water sources.
3 - 2 Demonstrate an understanding of pump operations for supplying water from static water sources.
3 - 3 Demonstrate an understanding of pump operations by operating as an attack pumper and supplying various attack lines.
Practical Evolutions (devices would be used to simulate distance)
I . Operation from hydrant as supply pumper (3-1)
A. Engage pump
B. Charge supply lines from tank (3" line(s))
C. Establish water supply from hydrant
D. Change from tank operations to hydrant operations
II. Operation from draft as supply pumper (3-2)
A. Engage pump
B. Charge supply lines from tank (4" or 5" line)
C. Establish water supply from static source
D. Charge from tank operations to drafting operations
III. Operation as attack pumper (3-3)
A. Engage pump
B. Charge attack lines from tank (master stream)
C. Change from tank operations to supply line
D. Operate relief valve
All four units would be operating simultaneously with each student operating each unit
IV. Students should be monitored to observe the following (use checklist to record successful completion of skills):
A. Smooth engaging of pump
B. Initial operation of pump from tank
C. Establishment of water supply
D. Smooth change from tank to other source
E. Operation of relief valve/pressure governor
F. Proper gauge pressures
G. Overall safety of operation
