APPLICATION

The motors are designed for use with close-coupled pumps having NEMA JP or JM

mounting end shaft dimensions.

In such applications, the pump impeller is mounted directly on the motor shaft.

All motors are designed for continuous duty service.

STANDARDS

Motors comply with NEMA standards MG1-1998,

efficiency EPACT compliant / tested according to IEEE 112, method B.

Motors are CSA certified.
