TurboDraft fire Eductor demo

- Members and explorers of the volunteer fire company in Malabar, FL test and train with their newly purchased TurbodDaft Fire eductor. Neighboring departments questioned the usefulness of this valuable piece of equipment - however the Town of Malabar was able to earn a much higher ISO rating due to their ability to demonstrate their profiency in deploying this valuable piece of equipment in the areas of thieir area with limited water supply.
Good video! Thank you!
Just a couple of thoughts, and tried and proven items that will up your GPM/Flow numbers. The first, return the water to a drop tank and draft from the tank. This eliminates all reduction of flow due to left over residual pressure being left in the hose. And second, though they looked small, eliminate all kinks and bends in the 5inch return line. Any bend such as the 3inch passing over or under the 5inch creates turbulence in the 5inch thus reducing the return flow. Also the difference between using 3 inch Vs. 2.5 inch hose to supply the system makes a significant difference. And lastly, if you had been able to meter the amount of water you were supplying to the device you would have seen 350 to 370gpm in your first test and approximately 400 to 425 in the second IF in the second test you also shortened the feeder line to 50 feet. We have a standard policy that if you have one section of 5 inch on the ground then you have 100' of 3 inch supplying it. Some below claim redundancy in your video, I find it to be documentation and proof of your efforts.
In the case where we returned the water to a drop tank, removed all the head pressure off the return hose and kept the return to 50feet we documented and videoed 1030gpm from the deck gun while using a 1250gpm Waterous pump.
@pete359ext Yes, although you can flow some water to your deck gun, hand lines, or supply lines as your strategy dictates. You don't have to fill your tank first, it can be gradual over a few minutes. Very good video, although it gets a little too redundant.
So if im correct the discharge off the engine (2 1/2)" creates a venturi and then fills the LD intake(5)"? and then once your tank is full you just run the Intake water through and out the deck gun.?
why is the deck gun psi more on the first test with long hose vs lower on second test with short run of hose?
what diameter is the pipe where the ventury effect is performed, inside the turbodraf
To be clear, the flows you are getting are all out of the deckgun, or are you including the 2 1/2" to the turbodraft?
what happens when you loose prime line. what happens to the pump? how are you set up to use a soft line from pond and it not collapse ?
You are not going to lose prime with a "positive " water supply! That Turbo Jet makes it the Same as being on a hydrant! Have you ever lost prime on a hydrant?
The booster tank is the original positive pressure source. The turbo draft does the rest once water return to the pump.
