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 mag-
netic 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 at
traction 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.
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 pre-
vents sparking should the motor bearings fail and the outer mag drive assembly runs out of round.
2. You must select an explosion-proof FTI motor or provide your own explosion-proof motor.
WARNING: Hot surfaces. DB Series pumps are capable of handling liquids with temperatures as high as 220ºF (104ºC). This may cause the outer areas
of the pump to become hot as well and could cause burns.
WARNING: Rotating Parts. This pump has components that rotate while in operation. Follow local safety standards for locking out the motor from the
power supply during maintenance or service.
WARNING: Chemical Hazard. This pump is used for transferring many types of potentially dangerous chemicals. Always wear protective clothing, eye protection
and follow standard safety procedures when handling corrosive or personally harmful materials. Proper procedures should be followed for draining and decon
taminating the pump before disassembly and inspection of the pump. There may be small quantities of chemicals present during inspection.
WARNING: The pump and associated components are heavy. Failure to properly support the pump during lifting and movement could result in serious
injury or damage to the pump and components.
WARNING: Never run pump at less than minimum flow or with the discharge valve closed. This could lead to pump failure.
Installation/Operation Precautions
CAUTION: This pump should never be operated without liquid in the casing. It is recommended that run dry protection be used. Optional electronic
power monitors are available to help protect against run dry. If the pump has a PTFE, ceramic or silicon carbide bushing, IT CANNOT BE RUN DRY WITH-
4
OUT CAUSING DAMAGE TO THE PUMP. However, the pump can operate without liquid in the casing if the pump has a carbon bushing. The exact length
of time the pump can operate dry with a carbon bushing varies with operating conditions and environment.
CAUTION: Never start or operate with a closed suction valve. Never operate with a closed discharge valve.
CAUTION: Always provide adequate NPSHa (net positive suction head available). It is recommended to provide at least 2 feet (61 cm) above the NPSHr
(net positive suction head required).
CAUTION: If pump is used on variable speed drive, do not exceed the frequency for which the pump was designed (for example, if the pump is a 50 Hz
model, do not exceed 50 Hz)
.
CAUTION: Use of a power monitor is strongly recommended for pumps with ceramic, PTFE or silicon carbide bushings. The power monitor will stop
the pump and help prevent damage if the pump should run dry. ATEX certified pumps MUST use a power monitor
.
Safety Precautions for ATEX Pumps
CAUTION: Proper o-ring material must be chosen for the fluid being pumped. Improper material selection could lead to swelling and be a possible source
of leaks. This is the responsibility of the end user.
WARNING: The pump must be checked for leaks on a regular basis. If leaks are noticed, the pump must be repaired or replaced
immediately.
WARNING: The pump must be cleaned on a regular basis to avoid dust buildup greater than 5 mm.
WARNING: ATEX pumps must use a power monitor, flow switch, pressure switch or similar device to help protect against dry running, closed discharge
valve and decoupling. Any of these conditions could lead to a rise in surface temperature of the pump.
Temperature Classification
The surface temperature of the DB Series pumps depends upon the temperature of the fluid that is being pumped. The following chart lists different fluid
temperatures and the corresponding pump surface temperature.
Fluid Temperature Maximum Surface
Temperature
70º F (27º C) 131º F (55º C) T6 85º C
