Jet Pump – TEFC

Single-phase and three-phase designs with TEFC enclosures, versatile specifications, and mounting options
WorldWide Electric Jet Pump motors are designed for use in residential and commercial water pumping applications. TEFC Jet Pump Motors — feature a high-torque and durable design to effectively power industrial, commercial, and residential pumping solutions such as water wells and more. They are available in a C-Face with a Removable Base.


Sample Part Number: NTJ1-36-56CB. Each model number contains the product family, horsepower, rpm, and frame size. Ratings for hp with a decimal will carry a decimal to the model number, i.e. 1.5 hp becomes NTJ1.5-36-56CB. Ratings for hp listed in fractions will drop the slash, i.e. 1/3 hp becomes NTJ13-36-56JB
