Key Features
- OEM-Specified Dimensions — Cut to exact 3/4 x 5/8 x 1-3/4 in specifications, ensuring flush seating in the keyway without shimming or grinding.
- Precise Shaft-to-Hub Engagement — Sized and hardened to maintain full contact across the keyway length, locking drive components securely in position under load.
- Broad MG30 Series Fitment — Compatible with MG30T2D, MG30M2D, MG30T3D, MG30M3D, and MG30 models covering fireproofing pump and mixer configurations.
- Prevents Slippage Under Torque — A worn or undersized key allows sprockets, pulleys, or impellers to rotate on the shaft, causing rapid component wear and loss of drive power.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, carrying the correct part number EM513233 for confident, catalog-verified replacement.
A woodruff or square drive key is a small but critical component that locks a rotating part — such as a sprocket, pulley, gear, or impeller — to a shaft so both turn together as a single unit. It sits in matching keyway slots cut into both the shaft and the hub, transmitting torque between the two. When a key shears, deforms, or wears, drive power is lost entirely or delivered unevenly, resulting in slipping components, accelerated shaft damage, and potential equipment failure. Replacing a damaged key promptly with a correctly dimensioned OEM part like the Multiquip EM513233 restores full power transmission and protects the surrounding shaft and hub from further wear.
