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. Refer to the performance
curve on page E-1 for the maximum
continuous operating speed for this
pump.
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.
Once the pump casing has been filled, the pump
will prime as necessary.
After filling the pump casing, reinstall and
tighten the fill plug. Do not attempt to oper­
ate the pump unless all connecting piping
is securely installed. Otherwise, liquid in
the pump forced out under pressure could
cause injury to personnel.
To fill the pump, remove the pump casing fill cover
or fill plug at the top of the casing and add clean
liquid until the pump is filled. Replace the fill cover
or fill plug before operating the pump.
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.
OPERATION
Lines With a Bypass
Close the discharge throttling valve (if so
equipped) so that the pump will not have to prime
against the weight of the liquid in the discharge
line. Air from the suction line will be discharged
through the bypass line back to the wet well during
