Pump pressure

== Pump Pressure ==
=== Normal ===
Discharge pressures up to and including 500psi / 3.45 MPa / 34.47 bar are defined as Normal Pressure. 
Type 1 and 2 fire apparatus are pump tested and rated at 150psi. Wildland apparatus, Type 3, 4, 5 and 6, and pumps having a volume of over 3000 USGPM are pump tested and rated at 100psi.
=== High Pressure (HP) ===
Discharge pressures between 500 psi / 3.45 MPa / 34.47 bar and 1,100 psi / 7.5 MPa / 75.84 bar are defined as High Pressure.
=== Ultra Hight Pressure (UHP) ===
Discharge pressures greater than 1,100 psi / 7.5 MPa / 75.84 bar are defined as Ultra High Pressure.
