SPARTAN VS PIERCE ENGINES
Pressure Control
We wanted to add a quick video that takes a look at how the "new" Pierce Engine's Relief Control System (The Pressure Governor) compares to the "old" Spartan Relief Valves (technically, they are part of the Waterous Pumps inside our Spartan Engine).
A HUGE thanks to Driver Engineer Nicholas Martin (Dallas Fire-Rescue, Station 49C) for his help in this video.
Other Differences For Dallas Fire Members between Spartan and Pierce Engines:
On Pierce Engines...
The gas pedal does not disengage when placed into pump gear.
The pump will automatically idle up or down to achieve the desired PSI that the pump is set to.
You cannot set the pump below idle pressure. For example, 90 psi pump idle pressure plus 90 psi plug gets you 180 PDP. You have to gate down the line to achieve lower pressures. Another option would be to pump in volume to deal with this issue.
Pierce engines only have a Class-A foam tank. No more Class-B foam
