The 56 Frame Totally Enclosed Three-Phase Jet Pump Motor is engineered for demanding fluid movement applications, distinguishing itself within its category through a specific combination of durability and universal compatibility. Its compact 56J frame is a industry-standard footprint, ensuring easy installation and replacement in a wide array of jet pump systems. A key advantage is its Totally Enclosed Fan Cooled (TEFC) construction, which provides superior protection against moisture, dust, and contaminants compared to open-frame designs, making it exceptionally reliable in harsh or humid environments. This motor is rigorously certified to meet UL, CSA, and CUS standards, guaranteeing compliance and safety for use in North American markets. Built with a robust rolled steel frame and offering a power range from 1/3HP to 3HP, the 56 Frame Totally Enclosed Three-Phase Jet Pump Motor delivers consistent performance and extended service life for commercial and industrial pumping duties.
This motor is specifically designed to serve as the prime mover for three-phase jet pumps, which are commonly used for deep well water extraction, booster service, and general water transfer in agricultural, industrial, and commercial settings. Its three-phase operation provides high efficiency and robust starting torque.
Key Attractions & Features:
Durable Construction: The motor is built with a rolled steel frame,
offering exceptional strength and resistance to physical impact and corrosion, ensuring longevity even in tough operating conditions.
Superior Environmental Protection: Featuring a Totally Enclosed Fan Cooled (TEFC) enclosure and an IP44 rating, it is effectively sealed against ingress of solid particles larger than 1mm and water splashes from all directions, making it ideal for damp, dirty, or dusty locations.
High-Performance Design: It incorporates a NEMA Design B configuration, which provides standard starting torque with low starting current, suitable for a broad range of pump loads. The 1.15 Service Factor allows the motor to temporarily handle overloads without damage, enhancing operational reliability.
Reliable Thermal Capacity: With Class F insulation (UL approved), the motor possesses a high thermal endurance margin, allowing it to run cooler and significantly extending its insulation life compared to lower-class designs.
