OPERATION - SECTION C

Review all SAFETY information in Section A.

Follow the instructions on all tags, labels and
decals attached to the pump.

Whether new installation or rebuild of re­
fueler, the following requirements apply:

1. It is essential that tank scale, dirt, and

any other foreign elements be removed
from the tank and piping prior to pump
installation.

2. The gearbox was shipped dry of lubri­

cant. Lubrication must be added before
any operation.

3. The pump must not be run dry of prod­

uct at any time.

This pump is designed for vehicular
mounting in petroleum service. Do not
attempt to pump corrosive liquids
which may damage the pump or endan­
ger personnel as a result of pump fail­
ure.

Never tamper with the governor to gain
more power. The governor establishes
safe operating limits that should not be
exceeded. The Gearbox provided on
this pump is designed for operation at a
maximum input speed of 1750 RPM
(06C) or 1900 RPM (06D). If operated at
a higher RPM, pump or gearbox compo­
nents 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 and gearbox are
properly lubricated (see LUBRICATION in MAIN­
TENANCE AND REPAIR
).

This pump is not self‐priming, but 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.

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
bleeder valves.

Once the pump casing has been filled, the pump
will prime as long as positive suction head is avail­
able.

GROUNDING

To eliminate electrostatic build‐up by the liquid be­
ing pumped, the pump must be grounded by at­
taching a ground wire to a ground rod (grounding
is not required if pumping water). Install the ground
rod in accordance with the National Electrical
Code and all local codes. Be sure the clamp or fas­
tener has made a tight electrical connection with
the rod.

Inspect and test the ground wire assembly
for conductivity. Replace broken or frayed
wire before resuming operation.
