Endurel® uses inverter duty motors instead of the regular non inverter motors. The units are manufactured to meet customer voltage requirements including 480 / 575 VAC / 30 – 60 Hz.
The pumps may be run across the line or using a VFD. Motor bearings are designed to handle impeller side loads associated with both vertical and horizontal mounting positions. The motor shaft has been extended and a ‘C’ flange motor end plate added to compensate for the increased shaft length. This facilitates the installation of the pump and impeller directly on the end of the motor shaft.
