Fire Pumps Flashcards
The __________pump has problems with a pulsating fire stream and is very susceptible to wear.
Piston pump
The amount of water pumped by a ______________pump depends on the size of the____________in the ____________and the speed of rotation
Rotary gear
Pockets
Gears
The ___________________is a positive displacement pump because each pocket in the ____________contain a definite amount of water
Rotary gear pump
Gears
In this type of pump the rotor is mounted off center inside the housing.
Rotary vane
One of the most common types of pumps used to prime centrifugal pumps.
Rotary vane pump
Consists of two gears that rotten in. Tightly meshed pattern in a water tight case.
Rotary gear pump
The efficiency of the_________pump depends upon the close tolerance between the __________and the wall of the cylinder
Piston
Piston
Single acting piston pump
Double acting piston pump
Rotary gear
Rotary vane
Positive displacement pump
Does not use positive action to force water out of the pump , rather it relies on the velocity of the water.
Centrifugal pump
All water and air are forced out of the pump body with each operating cycle.
Positive displacement pump
The modern fire apparatus is equipped with a _______pump as its main pump
Centrifugal
Used as a priming pump to get water into______________pumps during drafting operation
Positive displacement pump
Unlike _____________pumps,they can pump air
Centrifugal
The simplest of all fire apparatus pumps from the standpoint of design
Rotary pump
In this position water is directed into the first impeller and then Is discharged directly into the eye of the second impeller .
Series (Pressure)
