Booster Pumps
Sec III- 4
Preventive Maintenance
o
Place caps on all valves
o
Connect a positive pressure
source
o
Inspect the pump for leaks.
Drive Line and Flange Bolts
Check all drive line and flange bolts to ensure:
1. No bolts are missing.
2. All bolts are tight. Use a torque wrench to
torque bolts to the drive train manufacturer's
recommended specifications.
3. Bolts used are “Grade 8” strength.
Annual Pump Maintenance
o
Replace the pump gearbox oil. Use SAE EP-
90, 80W-90, or synthetic 75W-80 gear oil
that meets service rating of API GL-5 re-
quirements.
o
Check individual drain lines from the pump to
the multi-drain to ensure proper drainage
and protection from freezing.
o
Tank to pump flow rate
test.
o
Clean ESP Primer if in-
stalled.
o
Perform the yearly pump
test to check performance
levels. (See NFPA Stan-
dard 1911 for more details.)
Replace Gearbox Oil
1. Remove the magnetic drain plug from the
gearbox.
2. Drain the oil from the gearbox.
3. Inspect the magnetic drain plug. If of metal
filings are present on the drain plug, remove
the cooler or coverplate to visually inspect
and clean the internal components. Repair or
replace as necessary.
4. Replace the cooler or cover, if necessary.
Remove the oil fill plug, and replace the drain
plug.
5. Fill the gearbox with an approved gear oil
until the oil level is at the fill plug opening
(approximately 1 to 2 quarts).
6. Replace the fill plug.
Check Drain Lines to Multi-Drain
Drains are supplied on the pump and piping at
the lowest points where water could collect and
freeze rendering the pump useless. Most of
these drains are piped together to a multi-drain
to allow the entire system to be drained by one
valve.
It is necessary to inspect each line to the multi-
drain to ensure the entire system is draining
when the valve is operated.
Inspect each connection and verify the individual
lines to the multi-drain are free of debris. Repair
or replace any lines that are damaged, kinked,
or corroded.
Tank to Pump Flow Rate Test
Note:
This procedure is written for information
only. It does not supercede any local proce-
dure.
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 hoselines and nozzles to
flow the desired discharge rate.
