MARATHON MOTORS Globetrotter Close-Coupled Pump Motors, JP, TEFC

Marathon Globetrotter close-coupled pump motors are used to power close-coupled pumps in many industrial and commercial applications. They are highly efficient in providing a maximum starting torque and can operate without a run or start capacitor which may fail or wear out.

Working Mechanism

  • Electric motors convert electrical energy into mechanical energy for generating motion.
  • Force is produced within the motor through the interaction between a winding alternating (AC) or direct (DC) current and the magnetic field.

Features

  • Marathon Globetrotter close-coupled pump motors have Class F insulation to withstand temperatures up to 40 degrees Celsius.
  • They feature steel construction for structural rigidity and ball bearings to reduce motor friction.
  • These triple-phase units having a totally enclosed fan cooled enclosure, allowing air to flow through the motor and prevent overheating.
  • They allow continuous duty cycle operation with clockwise / counterclockwise shaft rotation, delivering speeds up to 3600 rpm.
  • These units permit flange / base horizontal mounting for ease of installation.

Standards and Approvals

  • CSA
  • UL
  • CE
  • NEMA

Frequently Asked Questions

What is a close-coupled pump?

A shared motor and pump shaft or a strong connection between the motor shaft and pump shaft inside the pump casing defines close-coupled pumps. Instead of being mounted on pump feet, the pump casing is fastened to the driving flange.

What is the difference between single, double and triple-phase motors?

  • Single-phase motor: Current flows through a single conductor.
  • Double-phase motor: Current flows through 4-wire conductors (2 for each phase).
  • Triple-phase motor: Current flows through 3 separate conductors.

What does continuous duty operation mean?

A continuous load is where the highest current is expected to operate continuously for three hours or more.

What is the difference between TENV and TEFC motors?

Totally enclosed non-ventilated (TENV) motors are designed without air openings, ideal for applications requiring frequent sanitising or cleaning. The TEFC (totally enclosed fan-cooled) motors come with an external fan to circulate outside air to the motor.
