Key Features

  • Precision OEM Tolerancing — Manufactured to exact dimensional specifications for the discharge plate assembly, maintaining the tight clearances that concrete pump bearings demand.
  • Direct Drop-In Replacement — Engineered to seat correctly in the discharge plate housing of LS-series pumps without machining or shimming.
  • Broad LS-Series Fitment — Confirmed compatible with LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, LS50TD, LS600P, LS300P, LS300G, and LS300GK concrete pumps.
  • Sustained Pumping Output — A correctly seated discharge plate bearing maintains proper plate rotation and sealing force, preserving consistent concrete delivery pressure and volume.
  • Genuine Multiquip Part — Supplied under Multiquip part number EM25803, giving you full traceability and confidence that the component meets the original design intent.

The discharge plate bearing supports the rotating discharge plate at the heart of the concrete pump's swing-tube or valve system. It allows the plate to rotate smoothly under high pressure while keeping it seated firmly against the wear plate, which is essential for maintaining a proper seal between each pumping stroke. When this bearing wears or fails, the discharge plate can shift or wobble, causing pressure loss, uneven concrete flow, and accelerated wear on surrounding components. Replacing the EM25803 bearing at the first sign of play or roughness in the discharge plate restores pumping efficiency and protects the broader valve assembly from secondary damage.
