The difference between any Pump and a Fire Pump
Assume @ Design Calculation ( Fire Pump )
Qd = 500 GPM ( FLOW RATE @ design ) & Pd = 10 bar ( pressure)
 |
| Design Calculation |
Conditions for Fire Pumps
1 - @ Q = 0 H shut off head < or = 140% Hd
H shut off head = 14 bar
 |
| shut off head |
2 - @ Q max - H ( not less than or = 65% Hd )
H = 6.5 bar ( H not less than 6.5 bar)
 |
| Maximum Flow Rate |
Conditions for fire pumps
- @ Q = 0 H shut off head < or = 140% HdH shut off head = 14 bar
- @ Q max - H ( not less than or = 65% Hd )H = 6.5 bar ( H not less than 6.5 bar)
