Safety Precautions

WARNING: READ THIS MANUAL COMPLETELY BEFORE INSTALLING AND OPERATING THIS UNIT. FAILURE TO FOLLOW THESE PRECAU-

TIONS 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: The SP Series are not recommended for pumping flammable or combustible liquids. During the priming process, the

pump atmosphere can become very dangerous should the pump fail to prime and overheat.

SP Series pumps can be used to pump non-flammable or non-combustible liquids in a hazardous area. However, it is important to follow
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.

2. You must select an FTI explosion-proof motor or provide your own explosion-proof motor.

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: 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, eye protection and follow standard safety procedures when handling corrosive or personally harmful materi-
als. 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 flow 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 2 1/2 gallons (9.5 liters) of priming fluid 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.

3

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 the frequency for which the pump was designed (for example,

if the pump is a 50 Hz model, do not exceed 50 Hz).

SP22 Capabilities

• Maximum Working Pressure: 90 psi (6.2 bar)

• Maximum Temperature: Polypropylene -180º F (82º C); PVDF – 220º F (104º C)

NOTE: Maximum temperature is application dependent. Consult a chemical resistance guide or the chemical manufacturer for

chemical compatibility and temperature limits.

• Maximum Lift: 25 feet (7.6 meters)

NOTE: Lift determined on fresh, cold water with 3” Schedule 40 pipe. Specific gravity affects lift capability. Divide 25 feet (7.6

meters) by the specific gravity to determine equivalent maximum lift.

• Solids: Maximum particle size is 100 microns for slurries and 1/64” (.4 mm) for occasional solids. Maximum hardness is 80 HS.
Maximum concentration is 10% by weight. If solids are being pumped, it is recommended that the pump have silicon

carbide components for best results. 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. FTI recommends using a 2” (50.8 mm) or 3” (76.2 mm)
strainer basket with 1/8” (3.2 mm) perforations. Regular strainer basket maintenance is required to prevent plugging and a

decrease in NPSHa so not to starve and damage the pump.

• Minimum Allowable Flow Rate

Do not allow the flow rate to drop below the minimum flow rate in the chart below:

3450/2900 rpm 1750/1450 rpm

10 US gpm (2.3 m

3

/hr) 5 US gpm (1.1 m3/hr)

• Maximum Allowable Motor Power

Do not exceed 7.5 kW (10 horsepower) for 50 Hz, 2900 rpm applications. For 60 Hz, 3450 rpm applications, the pump is capable
of starting a 15 horsepower motor but is limited to a maximum of 13 horsepower (9.7 kW) while running. Use the information in
the chart below to determine the maximum specific gravity capabilities by impeller trim for non-overloading applications. The
use of a power monitor is strongly recommended for 60 Hz applications above 10 horsepower (7.5 kW).
