Key Features
- Genuine OEM Material Grade — Manufactured from the same plastic compound spec as the original, ensuring correct dimensional tolerance and wear resistance within the pump housing.
- Drop-In Replacement — Engineered to seat exactly as the factory component does, requiring no trimming or modification to fit the ST-45HRM pump assembly.
- Confirmed ST-45HRM Fitment — Verified for use with the Multiquip ST-45HRM swing tube concrete pump.
- Maintains Pump Alignment — A correctly fitted bushing keeps internal pump components properly aligned, preventing premature wear on surrounding metal parts and maintaining consistent output pressure.
- Sourced Direct from Multiquip — Sold as an authorized OEM part through DHS Equipment, so you receive the same component Multiquip installs at the factory.
A plastic bushing serves as a low-friction interface between moving or stationary components inside the pump assembly, reducing metal-on-metal contact and absorbing minor misalignment during operation. In a concrete pump like the ST-45HRM, bushings help guide and stabilize internal moving parts under the constant stress of pumping abrasive material. When a bushing wears out or cracks, it can allow excessive play between components, leading to accelerated wear on surrounding parts and inconsistent pump performance.
