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 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 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 motor)
produce powerful 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 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 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 MSDB Series pump it is important to only pump liquids that are
water soluble (miscible) and 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.
