EBARA Fluid Handling 15
OPERATION – SECTION C
Review all SAFETY information in Section A.
Follow instructions on all tags, labels and
decals attached to the pump.
This pump is designed to handle mild
industrial corrosives, mud or slurries
containing large entrained solids. Do not
attempt to pump volatile; corrosive, or
flammable liquids which may damage the
pump or endanger personnel as a result
of pump failure.
Pump speed and operating conditions
must be within the performance range
shown on page 21.
PRIMING
Install the pump and piping as describe in
INSTALLATION. Make sure that the piping
connections are tight, and that the pump is
securely mounted. Check that the pump is
properly lubricated (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. Extend 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
considerable length of time.
3. The liquid in the pump casing has
evaporated.
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 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 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.
STARTING
Consult the operations manual furnished
with the power source.
Rotation
The correct direction of pump rotation is
counterclockwise when facing the impeller.
The pump could be damaged and
performance adversely affected by incorrect
rotation. If pump performance is not within
the specified limits (see the curve on page
21), check the direction of power source
rotation before further troubleshooting.
If an electric motor is used to drive the
pump, remove V-belts, couplings, or
otherwise disconnect the pump from the
motor before checking motor rotation.
Operate the motor independently while
observing the direction of the motor shaft, or
cooling fan.
