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 most
non‐volatile, non‐flammable liquids
containing specified entrained solids.
Do not attempt to pump volatile, corro­
sive, or flammable liquids which may
damage the pump or endanger person­
nel as a result of pump failure.
Pump speed and operating conditions
must be within the performance range
shown on page E‐1.
STARTING
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).
Consult the operations manual furnished with the
power source.
Rotation
The correct direction of pump rotation is counter­
clockwise when facing the impeller. The pump
could be damaged and performance adversely af­
fected by incorrect rotation. If pump performance
is not within the specified limits (see the curve on
page E‐1), check the direction of power source ro­
tation before further troubleshooting.
If an electric motor is used to drive the pump, re­
move 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 cool­
ing fan.
If rotation is incorrect on a three‐phase motor, have
a qualified electrician interchange any two of the
three phase wires to change direction. If rotation is
incorrect on a single‐phase motor, consult the liter­
ature supplied with the motor for specific instruc­
tions.
PRIMING
The pump will begin to prime upon startup. The air
in the suction line will be discharged from the prim­
ing chamber discharge line. Complete priming is
indicated by a positive discharge pressure read­
ing.
If full priming is not achieved, the discharge check
valve may be malfunctioning. If this occurs, shut
down the pump and consult the Maintenance and
Repair section of this manual for further details.
OPERATION
Leakage
No leakage should be visible at pump mating sur­
faces, or at pump connections or fittings. Keep all
line connections and fittings tight to maintain maxi­
mum pump efficiency.
Liquid Temperature And Overheating
The maximum liquid temperature for this pump is
160
_F (71_C). Do not apply it at a higher operating
temperature.
Overheating can occur if operated with the valves
in the suction or discharge lines closed. Operating
