Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design specifications, delivering the same dimensional accuracy and material grade as the pulley your machine shipped with.
• Correct Belt Engagement — Step profile matches the original pulley geometry, ensuring proper belt seating and consistent drive engagement across each speed stage.
• Broad MG30 Series Fitment — Compatible with MG30T2D, MG30M2D, MG30T3D, MG30M3D, and MG30 models, covering both fireproofing pump and mixer configurations in the MG30 family.
• Consistent Speed-Stage Performance — A correctly sized step pulley maintains accurate output speed ratios; a worn or damaged pulley causes belt slippage, speed variation, and uneven material output.
• Direct Bolt-On Replacement — Matches the original mounting interface, so the pulley swaps in using standard tooling with no machining or adaptation needed.

A step pulley is a multi-diameter drive pulley that allows the operator to select different drive ratios by moving a belt between the stepped grooves. Each step corresponds to a different output speed, giving the machine adjustable performance for varying application demands. When a step pulley becomes worn, cracked, or damaged, the drive belt can slip or jump between grooves, resulting in inconsistent speed, reduced output, and accelerated belt wear — making timely replacement essential to keeping the equipment running as intended.
