Standpipe PDP -
Initial pressure 100 psi. Be prepared to adjust based on circumstances
Sprinkler PDP -
Maintain 150 psi
Friction loss for 100’ of 2 1/2” -
10 psi FL per 100’ (fog/solid)
Deck gun PDP -
80 psi smooth bore, 100 psi fog
Add 10-25 psi FL to NP
Large ground monitor PDP -
80 psi smooth bore, 100 psi fog
Add 10-25 psi FL to NP
Add 25 psi per 100’ of 2 1/2” siamesed hose
Mini-monitor PDP -
100 psi
Add 40 psi per 100’ of 2 1/2”
Ladder pipe PDP -
150 psi within 100’
Adjust based on aerial flowmeter
At full ladder height expect to flow 180 psi
Do not exceed 200 psi
Use PSI mode for :
- Pumping handlines
- Pumping ladder pipes or master streams
- Supplying sprinkler or standpipe
Use RMP mode for :
- Relay pumping
- Charging LDH
- Establishing a draft
- PSI mode malfunction
- Pumping operations above 300 psi
Foam application : spill PDP -
Start at 100 psi PDP and increase until adequate foam production
Foam application : fire PDP -
Start with 200 psi PDP at the eductor inlet to obtain 125 GPM
Foam concentrate required at 3% :
500 gallon tank - 15 gal. (3 pails)
600 gallon tank - 18 gal. (4 pails)
1 3/4” handline tips :
3/4” -
7/8” -
15/16” -
3/4” - 100 GPM at 50 psi
7/8” - 150 GPM at 50 psi
15/16” - 180 GPM at 50 psi
2 1/2” handline tips :
1” -
1 1/8” -
1 1/4” -
1” - 200 GPM
1 1/8” - 250 GPM
1 1/4” - 300 GPM
Master stream and ladder pipe : 1 1/4” - 1 3/8” - 1 1/2” - 1 3/4” - 2” -

180 GPM solid (15/16”)
Whenever an increase in RPM does not result in a corresponding increase in PDP, what has happened?
You have maximized your water source
If an increase in PDP does not result in an apparent increase in volume, what has happened?
You have reached critical velocity
