    Default 1,250 GPM on a F-550?

    I've seen a lot of pumps on ford F-550's and normally they are in the 500-750 GPM range (sometimes a 1,000). I just saw on Rosenbauer's website "New Deliveries" section that they delivered a pumper with a 1,250 GPM pump on a F-550! Doesn't it seem like that is the pushing the capabilities of the chassis?

    Here is a link.

    Yes, that is an awfully large pump.

    Unless you are carrying enough hose and nozzles to flow 1250pgm, the large pump is of no benefit with the water tank being only 250gal.

    Ill hazard a guess.

    A) Could be a typo like the Rosenbauer 100 Tower with 500 gallon tank.

    B) Perhaps its a tender of some type. Limited access path or cartway to a large water supply.

    C) Its 250 GPM bigger than the neighbors.

    Interesting. Hope someone in the know speaks up.

    The pumps are the same size. You need the HP to power to capacity and add the required discharges.

    52shelby, There are towers with 500 gallon tanks. If fact I started a whole thread about it!

    I know of several 100' towers with 500 gal tanks. :-)

    I was just thinking that maybe it was a typo like the one Rosey info. Not talking stuff... I have heard of towers with 500 on board.

    I've seen a F550 with a 750 pump on it. Charlotte Me, built by Greenwood emergency vehicles. It's a "new generation" MAXIM. They had to go with the standard 5 speed transmission because the automatic PTO couldn't handle the load of the 750 gpm pump.

    I don't know if the transmission behind the 6.4 is that much beefier to handle a 1250 gpm.

    Looking at the pump from the backside, it could very well be a 1250. They must have a lot of urban interface problems there. I am going to look that town up.

    The Darley LDM series pump listed starts at 1000gpm, so I'm thinking no typo.

    The town is just west of Saratoga Springs about 20 miles. Located in the foothills of the Adirondacks. They may very well have interface issues. Wonder if that is the only reason for placing a pump on a truck that size?

    Maybe a 500 gpm max to get ISO credit as a pumper, but that would be the most practical reason I can think of, not knowing their intended application.

    Others could be:

    Clearance or access issues preventing the use of a larger rig.

    Money. A lot less expensive purchase price than a traditional 1250gpm apparatus.

    Multi-purpose. Applying the "Leatherman" principle to fire apparatus.

    Competition. A neighboring department has a 1000gpm apparatus.

    Town of Sebago(Me.)has a E-one mini with a 1000gpm pump on a F350 4x4 so I know it can be done. A 1250 would be pushing the upper limit for this vehicle. T.c.

    The LDM1250 is a midship pump not a PTO.

    Our neighboring FD has a 1250 gpm pump on an F550 4 door cab 4 wheel drive chasis. It is set up like a standard pumper and is massively overloaded.

    The pump, plumbing, booster tank, and water will weigh 4000+lbs using conservative estimates.

    I'd say they are using it for places that a normal pumper won't fit but if you all remember s&s made one called a mighty mites. on super duty ford's in the 90's and they had 7.3's and 1259 pump's

    North Queensbury Fire in upstate NY runs this F-550 as a water supply piece, which is what I thought the below unit might be used for. The link shows them pulling 1380 gpm at draft. It seems like the F-550 is an easily overwhelmed chassis (for a true engine), but in this specialty role it looks like it does a good job.

    Here's a link to some info on that apparatus: http://www.northqueensburyfire.org/engine1.htm

    According to the FD's website it's a 1000 GPM Hale. Hard to say for certain from the photos but I suspect it is a Q-Pak. I'm at home now so I don't have horsepower data in front of me but I'll post some numbers on 1000 & 1250 ratings tomorrow from the office.

    YAY! I guessed correctly. I think.

    Was the Q-PAK available in '01?

    Yes. It came out in the mid to late 1990's.

    Default 1000 & 1250 GPM Power Requirements

    Here are some horsepower and speed requirements for a couple of different pumps that can be rated at 1000 & 1250 GPM. RPM shown is the impeller speed, not engine speed. I'll list all four main test points for each model and rating.

    Pardon the rudimentary way these tables are going to show up, I'm not an HTML expert, LOL.

    Code:
    Waterous model CX end suction pump:
    
    1250 GPM Rating:
    GPM   PSI  RPM    HP
    1250  150  3690   146 
    1250  165  3835   161 
    875   200  3928   148
    625   250  4315   170
    
    1000 GPM Rating:
    GPM   PSI  RPM    HP
    1000  150  3510   117
    1000  165  3650   130
    700   200  3880   131
    500   250  4290   160
    
    Waterous model CS midship pump:
    
    1250 GPM Rating:
    GPM   PSI   RPM    HP
    1250  150   3253   143
    1250  165   3360   157
    875   200   3530   144
    625   250   3927   158
    
    1000 GPM Rating:
    GPM   PSI   RPM    HP
    1000  150   3139   115
    1000  165   3269   128
    700   200   3507   126
    500   250   3916   146
    Keep in mind, this is the horsepower required at the input shaft of the pump transmission, so it does not factor in your loss through the truck transmission, running a generator, AC, etc. Even so, as you can see, the horsepower required to run a 1000 or 1250 rating is not that high.
