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.

Safety Precautions
WARNING: READ THIS MANUAL COMPLETELY BEFORE INSTALLING AND OPERATING THIS UNIT. FAIL-
URE TO FOLLOW THESE PRECAUTIONS CAN RESULT IN SERIOUS INJURY OR DEATH.
WARNING: Magnetic eld hazard. This pump contains powerful magnets. Exposed magnets (pump not connected
to motor) produce powerful magnetic elds. Individuals with cardiac pacemakers, implanted debrillators, other elec-
tronic 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 specic recommendations before working with this pump.
WARNING: Magnetic force hazard. This pump should only be disassembled and assembled using the recommend-
ed procedures. The magnetic attraction is powerful enough to rapidly pull the motor end and the wet end together. Do not
place ngers 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 oppy discs and hard drives.
WARNING: Not Recommended for Pumping Flammable or Combustible Liquids. During the priming process the
internal pump atmosphere can become very dangerous should the pump fail to prime and overheat.
The SP Series pumps can be used to pump non-ammable or non-combustible liquids in a hazardous area. It is important
to follow these guidelines:
1. Select the Ns (non-sparking) 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.
2. Select an FTI explosionproof motor or provide your own.
WARNING: Hot surfaces. This pump is capable of handling liquids with temperatures as high as 220º F (104º C).
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 and eye protection, and follow standard safety procedures when handling corrosive or
personally harmful materials. Proper procedures should be followed for draining and decontaminating the pump before
disassembly and inspection of the pump. There may be small quantities of chemicals present during inspection.
WARNING: Never run pump at less than minimum ow or with the discharge valve closed. This could lead to pump
failure.

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.
CAUTION: This pump should never be started without the 0.6 US gallon /77 oz. ( 2.7 liters) of priming uid in the
housing. If the pump has a PTFE, ceramic or silicon carbide bushing, IT CANNOT BE RUN DRY WITHOUT CAUSING
DAMAGE TO THE PUMP. However, the pump can operate without liquid in the housing 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.
WARNING: Operation without priming or against a closed discharge valve can result in high temperatures that can
result in injury or damage to pump components.
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 60 Hz.

Solids: Maximum particle size is 100 microns for slurries and 1/64” (.4 mm) for infrequent particles.
Maximum hardness is 80 HS. Maximum concentration is 10% by weight. If solids are being
pumped, it is
recommended the pump has either ceramic or, for best results, silicon carbide components.
Pumping solids may lead to increased wear.
NOTE: While the pump is capable of being used in sump applications, it is NOT a trash pump. Care must be taken to ensure that debris
and foreign objects do not enter the pump or damage may result. Suggest using a 1” strainer basket with 1/32” (.8 mm) perforations
or 1 1/2” strainer basket with 1/8” (3.2 mm) perforations. Regular strainer basket maintenance is required to prevent plugging and
decrease in NPSHa so not to starve and damage the pump.
