OPERATION - SECTION C
Review all SAFETY information in Section A.
Follow the instructions on all tags, labels and de­
cals attached to the pump.
This pump is designed to handle highly
corrosive and abrasive industrial waste
materials and residues containing spe­
cified entrained solids. Do not attempt
to pump volatile, explosive or flam­
mable 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 E‐1.
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 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
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.
Starting procedures will vary slightly depending on
the pump application, type of priming device, and
type of drive.
Rotation
The correct direction of pump rotation is clockwise
when facing the pump drive shaft. 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
