Three ways to damage a pump - ANSWER-Over Heating
-Circulate tank water
-Crack unused port & open Drain.
Wear caused by debris & deposits in the water
-Flush hydrant
Cavitation
Vacuum Primer - ANSWER-Uses the vacuum in the intake
manifold on a gasoline engine.
Obsolete with diesel engines
Exhaust Primer - ANSWER-This Primer operates on the same
principle as a foam eductor. The exhaust gases are diverted to a
chamber where the velocity of the gases passing through a
venturi creates a vacuum.

Check valves prevent explosive gases from the exhaust system
from entering the pump & keeps water from entering the exhaust
system.
Rotary Gear pump - ANSWER-Power
-Electrically driven
-Driven from the pump transmission.
Internal Gears
Drive Belt
Used on Large capacity pumps.
Rotary Vane - ANSWER-Eccentric position of rotor.
Vanes are free to move within the mounting slot
Electric motor most popular power to drive this primer
Most commonly used priming pump.
Uses priming oil in the system.
Priming Oil System - ANSWER-Oil Reservoir must be at least 4
quarts. (SAE 30) good for 8 to 10 primes

Check the level of the priming oil after every pumping operation.
A vent hole in the oil line from the tank to the priming pump to
break the siphon and drain tank while pumping.
Two purposes Priming oil serves - ANSWER-Forms a film on the
inside of the housing & on the moving elements, providing a
better seal to allow the pump to prime faster.
The oil also acts as a preservative & minimizes deterioration of
the metal parts by inhibiting corrosion when the pump is not in
use.
Priming Pump - ANSWER-When the priming valve is operated it
opens the airway from the fire pump to the priming pump and
closes an electrical switch causing the priming pump to operate.
Electrically driven primers allow operator to pump and prime at
the same time.
Relief Valve - ANSWER-Can be used when charging additional
lines.
Not capable of compensating for a decrease in pressure.

Works best at draft when the difference between intake pressure
and discharge pressure is the greatest. (MUST BE 90 PSI)
Pressure Governor - ANSWER-Works by regulating the power
output of the engine (RPM) to maintain set pump discharge
pressure.
When excess pressure builds up, a tube from discharge side of
the pump transmits the rise to a governing device, which cuts
back the throttle.
Governing devices very with each manufacturer's design.
Intake Relief Valve - ANSWER-Protects intake side of pump
Water hammer
Dumps excess to the ground
Master Drain - ANSWER-Uses of the master drain:
-Drain the main pump housing (1st & 2nd stages)
-Drain the tubing to pump panel gauges
-Drain the auxiliary cooler.
