IMPORTANT NOTICE
U.S. Export Administration Regulations, pursuant to ECCN 2B350, prohibit the export or reexport to certain enumerated countries of
sealless centrifugal pumps in which all wetted materials are constructed from fluoropolymers without first applying for and obtaining a
license from the U.S. Bureau of Industry and Security (BIS). This affects all Finish Thompson magnetic-drive pumps constructed from PVDF
or lined with ETFE. Please contact the BIS (www.bis.doc.gov) or Finish Thompson with questions regarding the Regulations or a list of the
countries to which they apply.
Chemical Reaction Disclaimer
The user must exercise primary responsibility in selecting the product's materials of construction, which are compatible
with the fluid(s) that come(s) in contact with the product. The user may consult Finish Thompson, Inc. (manufacturer) and a
manufacturer's representative/distributor agent to seek a recommendation of the product's material of construction that of-
fers the optimum available chemical compatibility.
However neither manufacturer nor agent shall be liable for product damage or failure, injuries, or any other damage or loss
arising out of a reaction, interaction or any chemical effect that occurs between the materials of the product's construction
and fluids that come into contact with the product's components.
Safety Precautions
WARNING: READ THIS MANUAL COMPLETELY BEFORE INSTALLING AND OPERATING THIS UNIT.
FAILURE TO FOLLOW THESE PRECAUTIONS CAN RESULT IN SERIOUS INJURY OR DEATH.
WARNING: Magnetic field hazard: This pump contains powerful magnets. Exposed magnets (pump not connected to mo-
tor) produce powerful magnetic fields. Individuals with cardiac pacemakers, implanted defibrillators, other electronic medi-
cal devices, metallic prosthetic heart valves, internal wound clips (from surgery), metallic prosthetic devices or sickle cell
anemia must not handle or be in the proximity of the magnets contained inside the pump. Consult a health care provider for
specific recommendations before working with this pump.
WARNING: Magnetic force hazard. This pump should only be disassembled and assembled using the recommended
procedures. The magnetic attraction is powerful enough to rapidly pull the motor end and the wet end together. Do not
place fingers between the mating surfaces of the motor and wet ends to avoid injuries. Keep the drive magnet and impel-
ler assembly away from metal chips or particles, items with magnetic stripes like credit cards and magnetic computer media
such as floppy discs and hard drives.
WARNING: When pumping flammable or combustible liquids with a DB Series pump it is important to follow these guidelines:
1.
You must use a PVDF pump. PVDF has conductive carbon fibers added which allow it to be grounded when installed in
a properly grounded piping system or when a properly installed grounding strap is attached to a housing bolt. If PVDF
is not compatible with the liquid being pumped, you should consider an ETFE lined UC Series magnetic drive pump.
2. You must select the non-sparking (Ns) bronze bump ring option. The non-sparking ring is pressed into the clamp ring or
motor adapter and prevents sparking should the motor bearings fail and the outer mag drive assembly runs out of round.
3. You must select an explosion-proof FTI motor or provide your own explosion-proof motor.
When pumping non-flammable or non-combustible liquids in a hazardous area using a DB Series pump, it is important to take these guidelines:
1.
You must select the non-sparking (Ns) bronze bump ring option. The non-sparking ring is pressed into the clamp ring or
motor adapter and prevents sparking should the motor bearings fail and the outer mag drive assembly runs out of round.
