OPERATION --- SECTION C
Review all SAFETY information in Section A.
Follow the instructions on all tags, labels and
decals attached to the pump.
Do not operate an internal combustion
engine in an explosive atmosphere.
When operating internal combustion
engines in an enclosed area, make cer-
tain that exhaust fumes are piped to the
outside. These fumes contain carbon
monoxide, a deadly gas that is color-
less, tasteless, and odorless.
This pump is designed to handle dirty
water containing specified entrained
solids. Do not attempt to pump volatile,
corrosive, or flammable liquids which
may damage the pump or endanger per-
sonnel as a result of pump failure.
Never tamper with the governor to gain
more power. The governor establishes
safe operating limits that should not be
exceeded. The maximum continuous
operating speed for this pump is 1980
RPM.
PRIMING
Install the pump and piping as described in IN-
STALLATION. Make sure that the piping connec-
tions are tight, and that the pump is securely
mounted. Check that the pump is properly lubri-
cated (see
LUBRICATION in MAINTENANCE
AND REPAIR).
This pump is self priming, but the pump should
never be operated unless there is liquid in the
pump casing.
Never operate this pump unless there is
liquid in the pump casing. The pump will
not prime when dry. Extended operation of
a dry pump will destroy the seal assembly.
Add liquid to the pump casing when:
1. The pump is being put into service for the
first time.
2. The pump has not been used for a consider-
able length of time.
3. The liquid in the pump casing has evapo-
rated.
When installed in a flooded suction application,
simply open the system valves and permit the in-
coming liquid to evacuate the air. After the pump
and piping system have completely filled, evacu-
ate any remaining air pockets in the pump or suc-
tion line by loosening pipe plug or opening bleeder
valves.
Once the pump casing has been filled, the pump
will prime and reprime as necessary.
After filling the pump casing, reinstall
and tighten the fill plug. Do not attempt
to operate the pump unless all connect-
ing piping is securely installed. Other-
wise, liquid in the pump forced out un-
der pressure could cause injury to per-
sonnel.
To fill the pump, remove the pump casing fill cover
or fill plug in the top of the casing, and add clean
liquid until the casing is filled. Replace the fill cover
or fill plug before operating the pump.
