JM PUMP MOTORS
General Specifications:
Designed for continuous duty service on close-coupled pumps using
NEMA JM mounting provisions. All motors have a rigid mounting base
and NEMA JM pump shaft.
Mechanical Features:
Totally enclosed fan cooled construction for maximum life in dirty
or severe environments. Oversized locked bearing on shaft end
limits axial shaft movement. Drip covers are available as accessory
kits for 143-5JM and 182-4JM motors—see letter designations in
the table for the correct kit. LEESON 182-4JM frame motors have
ENCLOSED ENDSHIELDS AS STANDARD WITH FRAME VENTS MEETING THE
drip-proof requirement.
Electrical Features:
High efficiency copper windings with NEMA 1.15 service factors.
