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 equipment.
Installation
NOTE: Numbers in parentheses refer to parts as defined
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 1/4 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
assembly 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.
9. Tighten the retainer (6) 1/4 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 instruction
manual 308981.
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 adaptor 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.
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.
CAUTION

polypropylene components of the pumps. To prevent
potential injury or equipment damage, do not expose
pump or the plastic components to direct sunlight for
prolonged periods.
WARNING
TIPPING HAZARD
When mounting the stainless steel pump (24B674),
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
positionedonaflat,levelsurface.Unevenorslanted
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.
CAUTION
The bung adaptor (8) has 2.5 in. of adjustment to
accommodate slight variances in drum size. To ensure
that the bung adaptor does not come out of the retainer,
do not allow the bottom of the larger diameter of the
bung adaptor to extend more than 2.5 in. from the
retainer (6).
