Fire Engines Photos

Issued to the AFS in very large numbers, these Dennis "number two" trailer pumps were rated at 500 GPM at 100 PSI (2275 LPM at 7 AT).

Many were removed from their trailer and engine, and mounted on type A water tenders in the early 1950s, and the pump itself continued to be manufactured for many years and mounted on both Dennis and many other new fire engine chassis.

I am always interested when I see these trailer pumps referred to as Dennis No.2s as I believe them to be No.3s.
My local fire brigade bought a Dennis No.3 Trailer Pump in 1939 and the model pictured here is basically what they got, albeit the earlier 'TA' version with the open hose boxes. I have a piece of Dennis literature from the time which illustrates their No.2 model and it is quite different from what is shown here and similar in appearance to the No.1 model.
I may be wrong but I believe that because the No.3 TrP has a similar if not identical capacity to the No.2 pumps fitted in appliances, it gets labelled the same way.

Chris: My understanding is that the Dennis No:3 pump was the 900 gpm pump which was usually fitted to the F7, F12 and F24 series, often as a mid mount but also as a rear mount.

Both right, in a way. A number 2 pump but number 3 trailer pump!
