WEG 00336ET3E145JM-W22 Close-Coupled Pump Motor, 3 HP, 230/460V, 3-Phase, 143/5JM
Product Overview
The WEG 00336ET3E145JM-W22 is a 3 HP, three-phase close-coupled pump motor with a 143/5JM frame. This W22 configuration combines a TEFC enclosure, cast iron construction and a foot-mounted arrangement. Power Plus Retailers identifies it with SKU 5160433; the complete manufacturer catalog number is the reference for matching the motor to the required equipment.
A close-coupled pump motor must be selected for its pump interface as well as its power rating. The JM shaft and mounting arrangement are important mechanical details, and this product should be considered only for a pump assembly designed to accept the specified frame. A general-purpose motor with the same horsepower may have a different shaft extension or mounting interface.
The listed U.S. operating configuration is 230/460V, three-phase, 60 Hz with 2 poles. The two-pole design is intended for the corresponding pump speed class; confirm actual loaded operating speed from the motor's model-specific data. The motor supplies the mechanical drive; it does not by itself determine the pump's flow, pressure or hydraulic performance.
Key Features
- 3 HP motor output for a suitably matched pump drive.
- 143/5JM frame for close-coupled pump applications.
- Foot mounting and pump-facing mechanical interface to be checked against the pump drawing.
- 230/460V, three-phase, 60 Hz operating configuration.
- 2-pole design for selecting the required speed class.
- Totally enclosed fan-cooled construction with external cooling airflow.
- Cast iron housing; W22 motor family.

Applications
Use this motor in a close-coupled pump installation whose manufacturer specifies compatible horsepower, operating speed, voltage and JM mechanical dimensions. Potential uses depend on the pump system and its service requirements. No compatibility with a named pump brand or model is claimed without a dimensional and electrical comparison.
For replacement work, record the existing motor's catalog number, nameplate ratings and pump model. Check whether the installation requires this cast iron version or a different construction. Compare the complete frame designation and shaft drawing rather than relying on the general appearance of the motor or the horsepower alone.
Installation and Selection Notes
Before purchase, verify shaft diameter, extension, key or retention details, face register and mounting-hole arrangement. The pump's impeller attachment, seal arrangement and axial dimensions must suit the selected motor. Confirm support and alignment requirements with the pump manufacturer, and ensure the motor's feet and cooling clearances can be accommodated.
Have a qualified installer confirm the available supply and follow the delivered motor's connection diagram for the chosen voltage. Size starters, conductors, overload protection and disconnecting equipment using the actual nameplate data and applicable installation requirements. Amperage, exact full-load speed and electrical protection settings have not been inferred for this listing.
Review starting conditions, operating load, rotation and any variable-speed requirements with the equipment supplier. A TEFC enclosure does not establish submersible operation or suitability for every environment. Keep cooling airflow unobstructed and follow the manufacturer's installation and maintenance instructions.
What's Included and Shipping Notes
This listing identifies the motor. A pump, impeller, coupling, seal kit, control panel or installation hardware is not represented as included unless confirmed separately. Exact product weight, packaged weight and shipping dimensions remain to be confirmed. Spreadsheet frame-family shipping estimates are not presented as measured values.
