OPERATION
Review all SAFETY information in this manual.
Follow the instructions on all tags, labels and
decals attached to the pump.
This pump is designed to handle most
non-volatile, non-flammable liquids
containing specified entrained solids.
Do not attempt to pump liquids for
which the pump, driver and/or controls
have not been approved, or which may
damage the pump or endanger personnel
as a result of pump failure.
PRIMING
Install the unit and hoses as described in this
manual.
Make sure that the piping and hose connections
are tight, and that the unit is securely
mounted. Check that the pump is properly
lubricated
(see LUBRICATION 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 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 re-prime as necessary.
After filling the pump casing, reinstall
and tighten the fill plug. Do not attempt
to operate the pump unless all connecting
piping and hoses are 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.
