3. Pumping hazardous, flammable, or combustible liquids
should only be done in buildings, rooms, or areas suited for
this purpose. (See NFPA 30, NFPA 78, NFPA 80, NFPA 251,
NFPA 704, other suitable NFPA codes, OSHA, insurance
companies, local codes and ordinances.)
When filling cans, drums, etc. with combustible or flammable liquids,
both containers (container pumping from and container pumping to),
should be bonded and grounded to dissipate possible accumulations of
static electricity and minimize sparks caused by static electricity. (Refer
to NFPA 77 for specifics and further details.) Removal of outer
garments in work areas where there may be flammable or explosive
liquids, which are ignitable with low electrical energy can be fatal and/or
cause property damage. (Refer to NFPA 56A and NFPA 77 for further
details.)
4. The WARNING and instructions that follow pertain not only to
gasoline, but to any flammable, combustible or hazardous
fluid.
Gasoline is a highly flammable fuel. The improper use, handling, or
storage of gasoline can be dangerous. Prevent accidents by following
these safety rules.
a. Use gasoline only as fuel, never as a cleaning fluid.
b. Use only an approved container to hold or store gasoline.
Never store gasoline in familiar containers such as milk
containers or soda pop bottles.
c. Store gasoline in a cool location, out of the reach of children.
Never store gasoline near heat or an open flame.
d. Provide a fire extinguisher nearby when working with
gasoline. Be sure extinguisher is in operating condition
–
check the pressure gauge of indicator. Be familiar with its
proper use. Consult local fire department for the correct type
of extinguisher for your application. Extinguishers rated ABC
by the National Fire Protection Association are appropriate for
most applications.
e. Provide positive shut-off valves on all permanent fuel
supplies. Fuel lines must be of steel piping, adequately
secured, and free from leaks.
f. Provide adequate ventilation, and clean up any spills when
handling or pumping flammable liquids.
g. POSITIVELY NO SMOKING!
5. Do not use torches or apply fire to this pump for any reason.
6. Secure the discharge line before starting the pump. An
unsecured discharge line will slip, possibly causing personal
injury and/or property damage.
7. Do not over tighten nonmetallic, threaded fittings. One full
turn past hand tight is usually enough to prevent leakage.
Teflon® sealant tape is provided and should be used on all
threaded joints, including the spout.
8. Check hoses for weak or worn conditions before each use,
making certain that all connections are secure.
9. Periodically inspect pump and system components. Perform
routine maintenance as required.
10. Drain all liquids from the system before servicing.
Any pump used to transfer flammable liquids must be stored in a well-
ventilated area after use.
PERSONAL SAFETY
1. Wear safety glasses at all times when working with pump.
2. Wear a face shield, proper apparel and suitable respiratory
equipment when pumping hazardous chemicals.
3. Keep work area clean, uncluttered, and properly lighted.
Replace all unused tools and equipment.
4. Keep visitors at a safe distance from the work area.
5. Make workshop childproof with padlocks, master switches,
and by removing starter keys.
Failure to follow all General Safety Information can result in a
fatality, personal injury and/or property damage!
ASSEMBLY AND INSTALLATION
(Refer to Figure 1)
1.
Screw bung adapter (Ref. No. 3) into drum with threaded
end down.
2. Screw spout (Ref. No. 1) into pump casing (Ref. No. 2).
3. Screw suction tube (Ref. No. 4) into base of pump casing.
Use Teflon® Sealant tape provided.
4. Insert pump assembly into drum through bung adapter and
tighten butterfly screw by hand. Do not use wrench or tool to
tighten butterfly screw.
Not for use with water or other liquids that may cause corrosion.
Assembly and Installation
(Refer to Figure 2)
1.
Remove one hex nut from handle shaft and place it into hex
indent of crank arm (Ref. No. 10).
2. Finger-tighten remaining nut against handle.
3. Feed shaft through crank arm, then thread into hex nut.
When shaft is fully threaded, use wrench to tighten hex nut.
NOTE: Handle should spin freely on shaft when properly assembled.
4. Place crank arm assembly onto rotor shaft (Ref. No. 3).
Align fastener with indent on shaft before tightening. Do not
over tighten!
5. Assemble discharge spout (Ref. No 5) and screw into
casing (Ref. No 4). Union provided in spout allows tip to be
rotated 360º depending on dispensing needs.
IMPORTANT: All threaded pipe connections must be airtight in order
for pump to prime and work properly. Use Teflon® tape (provided) on
all connections. Do not over tighten.
6.
Assemble suction tube (Ref. No. 12) and attach strainer
(Ref. No 13).
7. Place bung adapter assembly (Ref. No. 7) over suction tube
with threaded end facing down. Then connect suction tube
assembly to base of pump casing.
8. Insert pump assembly into drum and tighten bung adapter.
Tighten thumb screw by hand. Do not use wrench or tool to
tighten thumb screw.
OPERATION
1.
Rotate handle rapidly several times in a clockwise direction
to prime. If pump does not prime, refer to “Troubleshooting
Chart” section.
MAINTENANCE
Periodically inspect the pump assembly and suction tubes for weak or
worn condition. Make certain that all connections and fasteners are
tight and secure. Perform routine maintenance as required.
