NWOV Elevator Pump-to-Motor Coupler - National Wheel-o-vator

High‑quality motor‑to‑pump coupler compatible with many National Wheel‑O‑Vator elevators, available in standard, severe duty, and assembly hub variants.

This coupler replaces the connection between the motor and the hydraulic pump in many National Wheel‑O‑Vator elevator power units. The yellow standard‑duty version is the common solution for typical indoor installations. The black severe‑duty version is designed for outdoor, extreme‑use or high‑vibration applications. Two assembly variants (both yellow) include integrated hubs for ease of installation: one with ¾″ to ¾″ hubs and the other with ¾″ to ⅞″ hubs. These assemblies streamline replacement in systems where hub bore adaptation is required.
