Its primary function is to ensure precise and rigid shaft alignment, completely enclosing the drive coupling to protect the operator and equipment. Its one-piece structural design completely eliminates the need for external supports, welded bases, leveling shims, and additional coupling guards.\u003c\/p\u003e\n\n\u003cp data-path-to-node=\"7\"\u003eMachined with high-precision technology (following Hydro-Craft and Magnaloy industrial quality standards), each mount ensures extreme concentricity within .003” between the motor and pump pilots.
