Grounding
WARNING
FIRE AND EXPLOSION HAZARD
This unit must be grounded. Before you
operate it, ground the system as
explained in this section. Also, read Fire
and Explosion Hazard on page 3. For
further grounding information, read the
Grounding section in instruction manual
308981.
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, ground the pump
and all other equipment used or located in the pumping
area. Check your local electrical code for detailed
grounding instructions for your area and type of equip-
ment.
Installation
NOTE: Numbers in parentheses refer to parts as de-
fined on the parts list on page 8 and the parts drawing
on page 9.
1. Remove the knurled bung adaptor (5) and the bung
gasket (2) from the bung adaptor base assembly
and install it onto the 55-gallon drum.
2. Tighten ¼ turn past hand-tight to ensure that the
bung gasket (2) engages the drum cover.
3. If an air-tight seal is required, place the white foam
gasket (9) in the recess on top of the bung adaptor
(8).
4. Loosely attach the pump to the mounting plate with
the 4 washers (4) and 4 screws (1) provided.
5. Apply sealant to the threads of the suction tube
(101).
6. Insert the threaded end of the suction tube (101)
through the bottom of the bung adaptor base as-
sembly and tighten it into the inlet manifold of the
pump.
7. Tighten the four screws (1) that attach the pump to
the mounting plate (7).
8. Insert the assembly into the drum through the bung
adaptor (5) installed on the drum.
TIPPING HAZARD
When mounting the stainless steel pump
(D54311), ensure that the offset mounting plate
(7) is positioned so that the pump is mounted
over the drum to prevent tipping when the fluid
level in the drum is low.
These units should be used only on drums
positioned on a flat, level surface. Uneven or
slanted surfaces could cause the drum to tip
over.
Do not relocate a drum with the unit mounted in
the bung hole. When the unit is mounted, the
center of gravity is too high for stability when
moving the drum.
WARNING
CAUTION
The bung adaptor (8) has 2.5” of adjustment to ac-
commodate slight variances in drum size. To ensure
that the bung adaptor does not come out of the retain-
er, do not allow the bottom of the larger diameter of
the bung adaptor to extend more than 2.5” from the
retainer (6).
9. Tighten the retainer (6) ¼ turn past hand-tight to
ensure the PTFE o-ring (3) seals against the bung
adaptor base assembly.
10. Ground the pump and the system. Refer to instruc-
tion manual 308981.
TOXIC FLUID HAZARD
Read the Toxic Fluid Hazard
information on page 3.
11. Follow the installation procedure in instruction
manual 308981 to complete the installation of the air
and fluid lines to and from the pump.
12. Open the second hole in the drum cover to
introduce make-up air or inert gas. The bung adap-
tor and bung adaptor base seal against the drum.
Failure to provide make-up air or inert gas could
cause the drum to collapse. If necessary, take
applicable steps to ensure the make-up air is dry
and that dangerous gases do not escape from the
drum.
13. To operate the pump, follow the procedures in
instruction manual 308981.
