Fire Pump Motors

Product catalog summary

Overview: The document outlines the specifications and features of fire pump motors, detailing their applications, construction, and efficiency ratings. It includes information on various models with different horsepower (HP), revolutions per minute (RPM), frame sizes, and voltage options.

Specifications: The motors range from 3 to 500 HP, with RPM options of 3600 and 1800. They are available in frame sizes such as 256T, 284T, 324T, and 449TS. The nominal efficiency ranges from 85.5% to 95.8%, and all motors have a service factor of 1.15. Voltage options include 200/400, 230/460, and 460 volts.

Applications: Designed for fire pump duty, these motors should be installed according to NFPA-20 standards. They are suitable for clean, dry environments (drip-proof motors) and damp, dusty, and dirty environments (TEFC motors). They are not recommended for use with variable frequency drives.

Features: Key features include EPAct efficiency, ball bearings, grease fittings with plugs, NEMA Design B, Code G, and dual voltage motors with 12 leads suitable for Y-Delta, Low Voltage PWS, and Across The Line Start. The motors are UL Listed, CSA Certified, and CE Marked, with a maximum ambient temperature of 40°C.

Construction: Motors with a 250 frame are constructed with rolled steel, while those with a 280 frame and larger are made of cast iron. All motors are painted red.

Connection Diagrams: The document includes connection diagrams for motors with paralleled leads, which must be paired correctly according to the diagrams provided.

NEMA Quick Reference Dimensional Chart: A dimensional chart is provided for various frame sizes, detailing measurements such as frame diameter, shaft length, and bolt hole dimensions.

Additional Specifications: The document lists multiple motor models with specific measurements, identified by unique codes (e.g., 284TS, 324U, 5011LS), including dimensions like length, width, height, bore size, and bolt size.

Procedures and Recommendations: It is recommended to contact a Lincoln Sales Representative for dimensions not shown and to refer to the Leeson 1050 catalog for additional 'C' dimensions, suggesting consultation with experts or additional resources for comprehensive information.

Contact Information: For further inquiries, contact details are provided, including a website, phone numbers, and an email address for Leeson, part of Regal Beloit Corporation.
