1921 Dennis 'N' Type pump escapeFA1075 is a 1921 Dennis 'N' Type pump escape. It is fitted with a 60HP White and Poppe 4 cylinder engine coupled to a Dennis 4 speed gearbox via a two Power Take Off drives. The first PTO is for the main Gywnne 1000gpm pump. It is a 3 stage turbine pump with a twin piston exhauster for priming. The second PTO is for the hose reel pump which can be supplied from the internal 50 gallon tank. Although the engine is very powerful, the braking system is rather rudimentary. There are no brakes on the front wheels, and only cam operated brakes on the back wheels. No friction material is used, just cast iron against cast iron. These brakes are only operated by a lever located alongside the gear change lever to the right of the driver. There is an additional foot operated transmission brake which is for emergency use only.
