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 offers 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 reac-
tion, 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
: Magnetic field hazard: This pump contains powerful magnets. Exposed magnets (pump not connected to motor) produce power-
ful magnetic fields. Individuals with cardiac pacemakers, implanted defibrillators, other electronic medical 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 mag-
netic 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 impeller 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.
IMPORTANT INFORMATION - READ ME FIRST!
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.
WARNING: READ THIS MANUAL COMPLETELY BEFORE INSTALLING AND OPERATING THIS UNIT. FAIL-
URE TO FOLLOW THESE PRECAUTIONS CAN RESULT IN SERIOUS INJURY OR DEATH.
