The Multiquip CM389818 Inner Mixing Arm TMS2000 is a genuine OEM replacement designed for Collomix Mixers. As a direct OEM component sourced through Multiquip, this part is built to the same specifications as the original, ensuring consistent fit and function. The CM389818 is the correct inner mixing arm for TMS2000-series Collomix mixing equipment, making it the dependable choice when the original arm is worn or damaged.
Key Features
- OEM-Grade Material Construction — Manufactured to the same material and dimensional standards as the original inner mixing arm, maintaining the torque transfer and structural integrity that the TMS2000 mixing system demands.
- Direct-Fit Replacement — Engineered to drop in as an exact replacement for the stock inner arm on Collomix TMS2000 mixing units, aligning with the existing drive hub and outer arm geometry.
- Confirmed Fitment for Collomix TMS2000 Mixers — Part CM389818 is specifically designated for TMS2000-series Collomix equipment; always verify your model before ordering.
- Consistent Mixing Action — The inner mixing arm works in tandem with the outer arm to generate the counter-rotating agitation that fully homogenizes materials; a worn or bent arm produces uneven mixing and incomplete blending.
- Genuine Multiquip OEM Part — Supplied through the Multiquip OEM parts network, so you receive an authenticated component backed by the manufacturer's quality chain.
The inner mixing arm is a core agitation component inside the TMS2000 mixing drum. It rotates in opposition to the outer arm, creating the counter-rotating action that thoroughly blends mortars, adhesives, and similar materials from the center outward. When the inner arm becomes bent, cracked, or worn, mixing efficiency drops noticeably — materials stay unmixed at the center of the drum, batch consistency suffers, and additional strain is placed on the drive system. Replacing a damaged inner arm with a genuine OEM part like the part restores proper mixing geometry and protects the surrounding drivetrain components.
