Three-Phase JP Close-Coupled Pump Motor

The Three-Phase JP Close-Coupled Pump Motor is a specialized motor designed for pump applications. Its close-coupled design features a direct connection between the motor and the pump body. This structure not only saves installation space but also improves transmission efficiency and reduces maintenance requirements. This series of motors covers a power range from 1HP to 10HP, offering both 2-pole and 4-pole options to adapt to different flow and head requirements. Its frame sizes include 140JP, 180JP, and 210JP, ensuring good mechanical strength and versatility. The motor features a Totally Enclosed Fan Cooled (TEFC) enclosure and an IP44 protection rating, effectively preventing the ingress of solid objects and water splashes, ensuring stable operation even in harsh environments. Its Class F insulation system (UL approved), combined with a 1.15 service factor, provides the motor with a certain capacity for short-term overload. It holds various international certifications such as CSA, CUS, UL, as well as energy efficiency certifications like EEV and EPACT (CC), meeting the access requirements for global markets.

Product Features & Advantages
Power & Frame Configuration: The motor power range covers 1HP to 10HP, and offers both 2-pole (approx. 3600 RPM) and 4-pole (approx. 1800 RPM) speed options, providing flexibility to match various pump operating conditions. The frames use specifications like 140JP, 180JP, and 210JP, all constructed from rolled steel, making them robust with good heat dissipation properties.

Superior Craftsmanship & Materials: The motor stator winding utilizes 100% pure copper material, which not only ensures high electrical conductivity efficiency but also reduces heat generation, extending the motor's service life. Optimized electromagnetic and airflow designs result in the motor housing maintaining lower temperatures during operation while producing minimal noise, offering users a safer and more comfortable environment.

Robust Protection & Cooling Design: The motor features a Totally Enclosed Fan Cooled (TEFC) enclosure and achieves an IP44 protection rating. It effectively prevents water splashes from all directions and the ingress of solid objects larger than 1mm, making it suitable for use in dusty or humid industrial environments. For the long shaft extension design of the JP series, when pumping high-temperature fluids, it increases the distance between the impeller's hydraulic center and the motor bearings, aiding heat dissipation and thereby extending the service life of the bearings and related seals.

Authoritative Certifications & Reliability: The product has passed CSA, CUS, and UL certifications. Its insulation system meets Class F standards and is UL approved. Furthermore, it complies with the EPACT (CC) and EEV energy efficiency standards, ensuring high efficiency, energy savings, and reliable operational performance.

Wide Range of Applications: This motor is specifically designed for close-coupled installation with pumps. It is widely used in scenarios such as water supply and drainage systems, fluid transport, and circulation systems. Its compact structure is particularly suitable for installations in spaces with limited room, making it an ideal power source for many industrial and commercial pump systems.
