IL OSFM FAE (Section III Pumps)
1. Common pump capacities
a. 750-2000 GPM
i. 750 (Minimum in step with NFPA 1901)
ii. 1000
iii. 1250
iv. 1500
v. 1750
vi. 2000
2. Define Net Pump Pressure
a. Every pump is needed to supply the subsequent:
i. A hundred% Capacity at one hundred fifty PSI Net Pump Pressure (1000 GPM)
ii. 70 % Capacity at 2 hundred PSI Net Pump Pressure (seven-hundred GPM)
iii. 50 % Capacity at 250 PSI Net Pump Pressure (500 GPM) - ANS-Identify the features of
hearth department pumpers (OSFM 11-3-3, NFPA 1002, 5-2.1)
1. Pressure
a. Supplying strains over two hundred PSI
2. Volume
a. Over ½ (50%) ability of pump
b. When related right into a sprinkler system.
3. Design of multi-degree pumps - ANS-Identify when a pump need to be operated in stress
or volume mode.
(OSFM eleven-3-four, NFPA 1002, 3-2.1, NFPA 1901, 12-2.Three.1, NFPA 1911,
three-three.4)
1. Pump Drives
a. Direct pressure (front established pumps)
i. Pump force equipment is bolted without delay to harmonic balancer of engine.
Ii. Provides both stationary or pump and roll ability
iii. Frees up midship region for larger tanks or device
iv. Usually restrained to 750 GPM
2. Split shaft geared pump transmission (midship pump)
a. Most famous
b. Does now not permit for pump and roll skills
c. Pump gear case in line with truck transmission and differential
three. PTO
a. Pump is driven through truck transmission
b. Limited to pumps smaller than 500 GPM
c. Has pump and roll functionality
d. Used on brush motors, ARFF apparatus, preliminary hearth attack vehicles or mobile
water materials
e. Not for aerials
