Why This Product

TEFC Construction — Totally Enclosed Fan Cooled

Totally Enclosed Fan Cooled motor is sealed against moisture, dust, and contaminants — no direct path for liquid or debris into the motor windings. Required for all outdoor, wet, and industrial environment installations.

NEMA Frame — Standard Interchangeability

Standard NEMA motor frame (56C, 143TC, 145TC, 182TC, etc.) allows direct replacement with any major manufacturer's motor. No custom parts, no factory service required when only the motor has failed.

IE3 Premium Efficiency

IE3 Premium Efficiency motors meet NEMA Premium and US federal minimum efficiency requirements. Reduced energy consumption compared to standard efficiency motors — particularly meaningful for continuous-duty pump applications.

Matched for Grundfos Pump Frames

WEG and Baldor motors supplied through Grundfos are selected and tested for direct compatibility with Grundfos CR, NBS, and NK pump ends — bolt pattern, shaft size, and shaft length are confirmed matches.

Class F Insulation

Class F insulation withstands winding temperatures up to 155°C — providing substantial thermal margin above the rated operating temperature. Motor service life is exponentially longer when insulation is not operated at its thermal limit.

Available in 1-Phase and 3-Phase

Available in single-phase (115/230V) for residential and light commercial, and three-phase (208-230/460V) for commercial and industrial installations. Same pump end, different motor specification.

Important Notices
Electrical Requires correctly rated supply — 230/460V, 3-Phase, 60 Hz. Install with correctly rated circuit protection and motor starter.
Temperature limits Do not exceed max fluid temperature per nameplate or max ambient temperature 104°F. Operating outside these limits will damage seals and motor insulation.
Dry running Do not run dry. WEG 56C pumps use the pumped fluid to lubricate the shaft seal — dry running destroys the seal within seconds. Install dry-run protection on all automatic installations.
Maintenance Refer to the Grundfos Installation and Operating Manual (IOM) for correct installation, commissioning, and maintenance intervals. Contact PumpStop for documentation.
