48112-019 Gorman-Rupp OEM Drive Coupler

The 48112-019 Gorman-Rupp OEM Drive Coupler is a factory coupling for Gorman-Rupp pump platforms. This coupler connects the drive motor or engine to the pump through a flexible element that manages torsional vibration and shaft misalignment.

Gorman-Rupp manufactures self-priming centrifugal pumps and submersible pumps for municipal, industrial, and construction applications. The drive coupler in these installations absorbs startup torque from across-the-line motor starts and cushions the drivetrain from the hydraulic shock that occurs during priming cycles and when solids pass through the impeller. A failing coupler introduces vibration that accelerates wear on the pump mechanical seal, which is one of the most common maintenance items on centrifugal pump installations.

The 48112-019 drops into the factory position on compatible Gorman-Rupp models. Remove the old coupling element, inspect both shaft interfaces, and set alignment per the pump installation guide before completing assembly.
