OPERATION − SECTION C
Review all SAFETY information in Section A.
Follow the instructions on all tags, labels and
decals attached to the pump.
This pump is designed to handle dirty
water containing specified entrained
solids. Do not attempt to pump volatile,
corrosive, or flammable materials, or
any liquids which may damage the
pump or endanger personnel 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 1900
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 as necessary.
When installed in a static lift application such as fire
truck filling, always leave enough liquid in the tank
to prime the pump prior to start-up.
NOTE
This pump is self-priming; however, it is not suited
for unattended reprime applications. In the event of
suction check valve failure and loss of prime, the
pump casing must be refilled through the fill cover
or fill plug.
STARTING
Consult the operations manual furnished with the
engine.
