nozzle used on one, 2-1/2” line should not be larger than 1-1/2” (38 mm) for accuracy in
measuring GPM (LPM).
Another alternative when a deluge gun is not available consists of a 1-1/4” (32 mm) nozzle
on one and a 1-1/2” (38 mm) nozzle on the other to pass 1,000 GPM (3,785 LPM). The sum
of the flow from both nozzles is the GPM (LPM) delivered by the pump. For good pitot gauge
accuracy, the nozzle pressures should be between 30 and 85 PSIG (207 and 586 kPa).
Performance Testing
NFPA standards require a 10% reserve in pressure at the capacity run when the
apparatus is delivered. See NFPA 1901 standards for testing procedures.
1. Test the relief valve (per NFPA 1901 standards):
 Set the relief valve flow rate capacity at 150 PSI (1034 kPa).
 SLOWLY close the discharge valves. The rise in pressure shall not exceed 30
PSI (207 kPa), or approximately 180 PSI (1241 kPa) operating pressure.
 SLOWLY open the discharge valves to re-establish the original pressure, 150
PSI (1,000 kPa).
2. Perform Steps 2 and 3 of the post operation maintenance procedures. Also see
Section 4.10 “Post Operation Procedures” on page 69.
3. Run the standard pump test in accordance with NFPA standards to check pump
performance.
4. Run the engine for 20 to 30 minutes to stabilize the engine temperature. Then run
the pump for:
 Two (2) hours at FULL capacity and at 150 PSI (1000 kPa)
 Thirty (30) minutes at 70% capacity and at 200 PSI (1400 kPa)
 Thirty (30) minutes at 50% capacity and at 250 PSI (1700 kPa)
 Additionally, an engine overload test is required which consists of pumping at
FULL capacity and at 165 PSI (1100 kPa) for ten (10) minutes.
5. If the apparatus does not reach performance levels, proceed to Section 6 “Trou-
bleshooting” on page 93.
6. Compare the results of this test to those from when the apparatus was delivered.
If the apparatus performance has dropped appreciably compared to its original
performance, it needs to be serviced.
Note: Apparatus test results should be on file with the delivery documents. If not, they may
be obtained from the apparatus manufacturer or from the original certifying authority).
