Key Features
- Genuine OEM Construction — Manufactured to the exact material and dimensional tolerances required for the ST-4125 pumping circuit, ensuring the plate seats and seals correctly against mating surfaces.
- Direct-Fit Replacement — Engineered to drop into the original mounting position on the ST-4125 without rework or modification to surrounding components.
- Confirmed ST-4125 Fitment — Verified compatibility with the ST-4125 swing tube concrete pump, so you can match the part to your machine before it ships.
- Maintains Pumping Efficiency — A correctly seated bottom plate supports consistent concrete flow and pressure through the swing tube circuit; a worn or damaged plate can cause pressure loss and material bypass.
- Wear-Surface Integrity — The bottom plate is a high-contact wear component in the pumping assembly; using an OEM part ensures the correct hardness and surface finish to handle abrasive concrete slurry.
The bottom plate is a critical wear component in the swing tube concrete pump assembly. It forms part of the sealing and wear interface at the base of the swing tube mechanism, maintaining the tight tolerances needed to direct concrete flow efficiently through the outlet. As the plate wears down from constant contact with abrasive concrete mix, output pressure drops and material can bypass the swing tube, resulting in reduced pump performance and potential damage to surrounding components. Replacing the bottom plate with a genuine OEM part restores the original sealing geometry and extends the service life of the broader pumping assembly.
