The Multiquip 0204102061 Unit Rotor ST-4100 is a genuine OEM rotor assembly designed for the Multiquip ST-4100 swing tube concrete pump. As a direct OEM replacement, this unit rotor is sourced and validated to the original engineering specification for the ST-4100, ensuring correct dimensional fit and proper integration with the pump's drive system. DHS Equipment supplies this part as an authorized Multiquip OEM component, giving contractors confidence they are installing the right part the first time.
Key Features
- Genuine OEM Construction — Manufactured to the original design specification for the ST-4100, delivering the same dimensional accuracy and material grade as the part it replaces.
- Direct Drop-In Replacement — Engineered to mount and connect exactly as the original unit rotor, with no reworking of surrounding components required during installation.
- ST-4100 Specific Fitment — Confirmed compatibility with the Multiquip ST-4100 swing tube concrete pump; verify your model code before ordering.
- Sustained Pumping Performance — A correctly functioning rotor maintains consistent fluid displacement through the pump, preventing output loss, pressure inconsistency, and unplanned stoppages on active concrete pours.
- Critical Drive Component — As a core mechanical element of the pump's output system, using an OEM-spec rotor protects adjacent components from the accelerated wear caused by an out-of-tolerance replacement.
The rotor is the central rotating element within the concrete pump's drive assembly, responsible for converting mechanical power into the displacement force that moves concrete through the system. In a swing tube pump like the ST-4100, the rotor must maintain precise rotational tolerances to keep output consistent and prevent internal leakage or pressure drop. When the rotor wears or fails, pumping efficiency drops noticeably — often resulting in sluggish output, uneven concrete delivery, or complete pump stoppage that can jeopardize a pour in progress.
