How to Read a Pump Motor Nameplate
Decode HP, RPM, voltage, frame, and enclosure on a motor nameplate so you can source the correct replacement.
The numbers that matter
Horsepower (HP), speed (RPM), voltage, and phase define the motor's output and electrical needs. Frame size and enclosure type (ODP, TEFC) define the physical fit and environment rating.
Service factor and insulation class indicate how much overload the motor tolerates and how it handles heat. Matching these specs is essential when replacing a motor.
Get a match, not just a guess
Photograph the nameplate before you call a company. A clear nameplate image lets a pump motor specialist source an exact or upgraded replacement quickly.
