    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: 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.

    examined after six months of operation or after 2,000 hours of operation. If the pump is used on fluids with solids, high temperatures or other items that could cause accelerated wear, then this initial examination should be sooner. After the initial examination of the internal components and wear items are measured, a specific maintenance schedule can be determined.

  • Page 11 Section II - Installation Mounting Pump foot should be securely fastened to a solid foundation. If the pump was received with plastic shipping shims, these shims may be used as additional support for the motor feet (though not required). Piping CAUTION: The NPSH available to the pump must be greater than the NPSH required.
  • Page 12 CAUTION: Do not operate the pump to check rotation until the pump is full of liquid or damage may occur even if the motor is “bumped” to check motor rotation direction. Check all electrical connections with the wiring diagram on the motor. Make sure the voltage, frequency, phase and amp draw comply with the supply circuit.
