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 MSDB 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.
2. You must select an explosion-proof FTI motor or provide your own explosion-proof motor.
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 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: 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 WITHOUT 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 the 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).
