@@picoro228 high volume fire pump, used alot in the uk and western Europe in area's where water availability is an issue, comes on two prime movers, within 15 minutes of arriving on scene can be pumping 7000 litres a minute down 3 km of 150 km hose from any open source of water though it can use a hydrant

Last year they had a capacity test over here in The Netherlands from a large static water canal, pumping 24,000 litres (about 6340 gallons) per minute! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ksOFJ3AdDoM.html
Fireman trying to sound way more sophisticated than they are, "drafting from a static source". Well you are actually pumping water, there is no definition of drafting in that respect, secondly the source is not static, clearly the water is flowing. Title should be, "operating (insert truck model) PTO water pump".
Wyatt Fisher What it is instead? I hardly believe that this fire engine has a second engine to operate the pump so I strongly believe that it is driven by a PTO.
The water source is static. A pond, lake etc is static unlike a fire hydrant which is under pressure and flows once it is open. A pond is useless unless you pull from it, draft. Most hydrants I have used have adequate pressure so as the actual pump pressure is not even needed.
I remember this quake followed the Whittier Narrows one month later. I was in Imperial County and felt all three quakes, Whittier and the Supersitious Hills quake, Elmore Ranch Nov 1987.
With no strainer on the intake line....drafting from a pond.... 1000-2000 gpm.... how long does the impeller last with all the dirt and sediment and the occasional crappie being introduced into the pump system?
What would you do in the instance of drop priming? Just open the intake and the tank fill let water fill the hard suction and then close the intake and then basically begin drafting by increasing RPM's? I have an engineer's test this friday and am trying to prepare.
That was a Kentucky shit hitch, that’s not how you hoist a saw. Not saying it wouldn’t get the job done… but that’s not how you do it with an 8 on a bite.
Ian Moniz it's the tank fill valve, once you open your tank to pump the water will revolve and heat up your pump, so by opening the tank fill valve you will send that revolving water back to your tank
Many Firefighters don't understand what it means when you have a 1500 or 1250 GPM pump. The rating is from a draft not tank to pump. Im sure this guy knows that. :)
dwc215 that is a good idea not to engage until you have everything set up, the only downside about that is that you have to go back into the cab and you might put mud on your floor boards,,,, haha JK, good observation!
His method here is far more common and makes more sense unless your engineer is extremely slow. To be idling your pump and opening up your tank to pump and your tank fill you'll be recirculating the water and at the same time getting your pump up to a good operating temp. It also saves going back in the cab.
