Preventive Maintenance
❑
The amount of discharge hose required for the service tests is dependent
on the flow requirements and capacity test point. Provide adequate hose to
discharge the rated capacity with a flow velocity less that 35 ft./sec. Also
see “Appendix D: Hose Friction Loss” on page 103 at the back of this
manual.
Since NFPA standards specify both GPM and pressure, it is usually neces-
sary to restrict the flow somewhat to build up the pump pressure. In normal
pumping, this restriction would be caused by the friction loss in the lines. It
is common practice to gate the discharge valves as required to maintain
pressure.
Performance Testing
Note: The NFPA standards require a 10% reserve in pressure at the capacity
run when the apparatus is delivered.
1. Check the relief valve according to the Relief Valve Test procedure. See
heading “Relief Valve Test” on page 42.
2. Perform steps 2 and 3 of the Post-Operation procedures. See Section
3.5 “Post Operation procedure” on page 40.
3. Run the standard pump test in accordance with NFPA standards to
check pump performance.
4. “Silencer” Series Pumps rated below 750 GPM are tested fifty (50) min-
utes per NFPA 1901, 14-13.2.3.2.
Run the engine to stabilize engine temperature, then run the pump for:
❑ Thirty (30) minutes at FULL capacity and at 150 PSI (10 BAR)
❑ Ten (10) minutes at 70% capacity and at 200 PSI (14 BAR)
❑ Ten (10) minutes at 50% capacity and at 250 PSI (17 BAR)
5. For Model “MBP” Series Pumps, rated at 750 GPM and 1,000 GPM
(2,839 and 3,785 LPM) a three (3) hour test is required, as follows:
❑ Two (2) hours at FULL capacity and at 150 PSI (10 BAR)
❑ Thirty (30) minutes at 70% capacity and at 200 PSI (14 BAR)
❑ Thirty (30) minutes at 50% capacity and at 250 PSI (17 BAR)
Additionally, an engine overload test is required which consists of pump-
ing at FULL capacity and at 165 PSI (11 BAR) for ten (10) minutes.
