Performance Testing Overview
The yearly standard performance test consists of checking the pumper, (according to
rating) at three capacities and comparing the results to when the pump was first
placed in service. This provides some measure of performance deterioration, if any.
(See Table 5-1: “Pump Ratings (GPM / LPM)” on page 82.)
A pump must be able to pump FULL rated capacity at 150 PSI (1000 kPa), 70%
capacity at 200 PSI (1400 kPa) and 50% capacity at 250 PSI (1700 kPa).
Tank-to-Pump Flow Rate Test
Note: This procedure is provided as a reference only. It does not supersede any local proce-
dures.
1. Fill the water tank until it overflows.
2. Close the tank fill line, bypass the cooling line, and all the pump intakes.
3. Attach sufficient hose lines and nozzles to pump the desired discharge rate.
4. With the pump in gear, open the discharge and begin pumping water.
5. Increase the engine throttle until the maximum consistent pressure is obtained on
the discharge gauge.
6. Close the discharge valve without changing the throttle setting. Refill the tank.
The bypass valve may be opened to prevent pump overheating.
7. Reopen the discharge valve and check the flow through the nozzle using a Pitot
tube or flow meter. Adjust the engine throttle to bring the pressure to the amount
previously determined.
8. Compare the flow rate measured to the NFPA minimum or the designated rate of
the pump. If the flow rate is lower, a problem may exist in the tank-to-pump line.
