How Much Gpm Is a Deck Gun

The deck gun might be a regional term, I have also heard it called the monitor, or the “Stang”, but we are talking about the engine mounted master stream. Most engine mounted master streams, fog, or a stack of smooth bore tips have a flow range of 500 to 1000 GPM.

What pressure do you pump a hand held solid bore nozzle?

Note that the standard rule is to use a pressure of 80 psi for a smooth bore tip nozzle in master stream operations. Higher pressures will create a broken and insufficient stream and an unstable operation in the elevated and portable modes, according to most fire stream books.

What pressure do you pump a fog nozzle?

Conventional fog nozzles have a fixed or selectable gpm setting. These settings correspond to a particular discharge orifice, or tip size. In order for a conventional nozzle with a fixed opening to operate at the correct nozzle pressure of 100 psi, the proper gpm flow must be supplied.
