Tuthill 88471 Motor 1/4 HP Single Phase TEFC 50 and 60 Hz
The Tuthill 88471 is a 1/4 HP single phase totally enclosed fan cooled motor rated for 50 and 60 Hz operation, supplied for Tuthill close coupled and adapter mounted pump packages. It is the drive half of a packaged pump unit rather than a pump part, which is why it is ordered by its own number rather than as part of a wet end.
A totally enclosed fan cooled frame keeps airborne dust, oil mist and washdown spray out of the windings, which is why it is the usual choice around a lubrication or transfer skid rather than an open drip proof motor. The dual frequency rating suits equipment that may be exported or run on either supply. Before ordering a replacement drive, check the frame and the mounting arrangement on the pump as well as the electrical rating, because a close coupled pump registers on the motor face and a base mounted one does not. Confirm the supply voltage and phase available at the installation, and remember that a gear pump is a constant torque load, so the motor has to be sized for the pressure the system actually runs at rather than the pressure it was commissioned at.

Frequently Asked Questions
Q: Will it bolt onto my pump?
Check the frame and the mounting face first. A close coupled pump has to register on the motor face, so the frame has to match exactly.
Q: Can it run on either 50 or 60 Hz?
It is rated for both, but the pump speed changes with the supply frequency, and so does the flow the pump delivers.
Q: What does totally enclosed fan cooled mean?
The windings are sealed from the surrounding air and the motor is cooled by an external fan, which suits dusty or wet locations far better than an open motor.
Q: Does it come with a starter or overload?
No. Motor protection is part of the electrical installation and is specified to the supply and the duty.
