Introduction: How to Pump a Fire Truck

Picture of How to Pump a Fire Truck

This Instructable is designed to give a person a basic knowledge about how to pump a fire truck quickly and efficiently

Step 1: Getting to the Scene

Picture of Getting to the Scene

In order to properly to pump a truck, one must get to the emergency scene in a safe and secure manner. Once the crew and engineer are safely on scene, the pumpinng set up and process can begin.

Step 2: Hitting the Hydrant

The most important yet overlooked aspect of pumping a fire truck is WATER. In order to have adequate pumping one must connect the main supply hose to the hydrant which in turn flows into the engine.

Step 3: Engaging the Pump

Once the truck is in position, it is time to begin pumping. First, the driver must engage the pump. To do this, the driver must use a button as seen in the picture. The driver must first place the button to neutral. Then the driver must place the button into pump then press the DRIVE button as if he were putting the truck into motion. Note: by doing this the truck will not move due to the airbrake being in use.

Step 4: Hose

Prior to pumping, the driver must make sure the hose is fully out of the rack and ready for water. Once this completed, the driver can continue.

Step 5: Priming the Pump

The driver must next prime the pump to prepare it for use. To do this, the driver must press the "PRIME" button for at least 10 seconds

Step 6: Tank to Pump

Once priming is complete, the driver can now begin to flow water. To do this, the driver must pull the lever labeled "Tank to Pump". This lever enables the water to be drawn from the tank on the truck into the pump which will then be sent to the hose.

Step 7: The Magic "Preset" Button

Next, the driver needs to use the pump throttle to assist in pumping. Most newer trucks come with a throttle panel that makes it easier to use. All the dirver has to do is press the "Preset" button and this automatically sets the throttle to 130 psi.

Step 8: Charging the Hose

Next, the driver can pull any lever and adjust it to the appropriate psi as required. By setting the preset, the driver can adjust the levers to the appropriate psi making sure that the appropriate pressure is flowing through the hose.

Step 9: Additional Helpful Steps

Next, if the driver chooses, they can pull the "Tank Fill" lever. This will enable the truck to refill its tank while still pumping water to the firefighters. That is as simple as firefighting gets!!!!

You forgot the most important part!

Friction loss calculations! I was taught by Chief Murphy (really that was his name) to pump ALL fog nozzles at 140 THEN do the calculations.

Math is HARD in the dark, while incoherent radio chatter is blaring, smoke is banked down to the ground (the wind always blows TOWARDS the pumper), and you are trying to manage multiple hand lines (always pulled off the other side of the truck from your panel so you can't see them) of varying lengths and a LDH supply line... And it's that house on Sunnyslope... (those that were there will get the reference)

It's been 20 years and IIRC you do the math for 2.5" hose of the flow rate you desire, perform a conversion to the size line you have, with additions for any appliances and fixtures, for gravity and more. Q^2*L???
