Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications for the Shaft Remixer, ensuring the agitation geometry matches the pump's hopper design exactly.
• Direct-Fit Replacement — Engineered to mount and connect the same way as the original shaft assembly, allowing a straightforward swap during scheduled maintenance or emergency repair.
• Confirmed Fitment — Compatible with ST-45HRM and ST-70 concrete pump models; always cross-reference your unit's model code before ordering.
• Sustained Mix Consistency — A properly functioning shaft remixer keeps concrete material agitated in the hopper, preventing segregation and maintaining a pumpable mix through the entire pour cycle.
• Authorized Parts Source — Sold by DHS Equipment as an authorized Multiquip parts distributor, so the part number EM25863 you receive matches exactly what the manufacturer specifies.

The shaft remixer is the rotating agitation component mounted inside the concrete pump's hopper. Its job is to continuously stir the concrete mix as it feeds into the pump cylinder, preventing the aggregate and cement paste from separating or stiffening before they reach the pumping mechanism. When the shaft remixer wears, bends, or fails, material flow becomes inconsistent, leading to blockages in the line and uneven output at the placement point. Replacing a worn EM25863 Shaft Remixer restores proper feed action and keeps the pump delivering a uniform, workable mix throughout the job.
