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 for vehicular
mounting in petroleum or clear water
service. Do not attempt to pump corro-
sive materials, or any liquids which may
damage the pump or endanger person-
nel as a result of pump failure.
The gearbox provided on this pump is
designed for operation at a maximum in-
put speed of 1850 RPM. If operated at a
higher RPM, pump components may be
destroyed.
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.
When installed in a flooded suction application,
simply open the system valves and permit the in-
coming liquid to evacuate the air. After the pump
and piping system have completely filled, evacu-
ate any remaining air pockets in the pump or suc-
tion line by loosening a pipe plug or opening bleed-
er valves.
Once the pump casing has been filled, the pump
will prime and reprime as necessary.
GROUNDING
To eliminate electrostatic build-up when pumping
petroleum products, the pump must be grounded
by attaching a ground wire to a ground rod
(grounding is not required when pumping water).
Install the ground rod in accordance with the Na-
tional Electric Code and all local codes. Be sure the
clamp or fastener has made a tight electrical con-
nection with the rod.
Inspect and test the ground wire assembly
for conductivity. Replace broken or frayed
wire before resuming operation.
STARTING
Consult the operations manual furnished with the
vehicle.
Rotation
The correct direction of pump rotation is counter-
clockwise when facing the input drive shaft. The
