Pump-Motor Coupling Bell - NEMA 284TC-286TC

The heavy-duty coupling bell housing (pump-motor mount) directly connects an SAE flange hydraulic pump to large-frame NEMA C-face electric motors (284TC and 286TC frames). 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.

Machined 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. This prevents vibrations, reduces premature bearing wear, and maximizes the lifespan of the flexible coupling under severe continuous duty conditions.

Verify your NEMA motor's frame size, your pump's SAE flange, and the total shaft length to confirm compatibility.
