Multiquip EM25801 Concrete Cylinder

The Multiquip EM25801 is a genuine OEM Concrete Cylinder designed for the LS-series hydraulic concrete pumps, including the LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, LS50TD, and LS600P. As a direct OEM replacement, this cylinder is manufactured to the exact specifications required for proper pump operation and long-term dependability in demanding concrete placement applications. Sourced from Multiquip and sold by DHS Equipment, the EM25801 is the correct part for keeping your hydraulic pump performing at full capacity. Confirm your model code before ordering to ensure a direct match to your machine's pump assembly.

Key Features

• Genuine OEM Construction: — Manufactured to exact bore tolerances and material hardness specs required for consistent concrete displacement under continuous hydraulic pressure.
• Direct-Fit Replacement: — Engineered to install directly into the pump housing of compatible LS-series machines, matching original mounting dimensions and port alignment.
• Broad LS-Series Compatibility: — Fits LS300, LS400, LS500, LS600, LS60TD, LS40D, LS40TD, LS50TD, and LS600P hydraulic concrete pumps.
• Sustained Output Pressure: — A properly functioning cylinder maintains full volumetric efficiency in the pump stroke, supporting consistent concrete flow and placement accuracy on the pour.
• Wear Resistance Under Load: — The cylinder bore is subject to continuous abrasion from concrete slurry; an OEM-spec replacement restores the tight clearances needed to prevent internal bypass and pressure loss.

The concrete cylinder is a core wear component inside a hydraulic concrete pump's pumping unit. It forms the precision bore through which the piston travels to draw in and push out concrete with each stroke of the hydraulic circuit. Over time, abrasive aggregate in the concrete mix wears the cylinder's inner wall, causing internal leakage, reduced output pressure, and inconsistent flow. Replacing a worn cylinder with a correctly specified OEM part like the EM25801 restores stroke efficiency and protects the piston and seals from accelerated wear caused by excessive clearance.
