NEMA Premium Efficiency NAE - Vertical Hollow Shaft - 400 HP

HIGH EFFICIENCY
HIGH THRUST DESIGN
CAST IRON CONSTRUCTION
OPEN DRIP PROOF (WP-1) ENCLOSURE

APPLICATIONS:

Designed primarily for deep well turbine pump applications. The coupling is equipped with a non-reverse ratchet, which prevents motor rotation from backspin at shutdown. These motors are built to NEMA standards and have special bearing arrangements to carry heavy thrust loads.
