Key Features
- Genuine OEM Material Integrity — Manufactured to Multiquip's original bore diameter and wall-thickness specifications, maintaining the hydraulic pressure integrity critical to concrete pump operation.
- Drop-In Replacement — Matches the original mounting interface and sleeve geometry so installation follows the factory service procedure without rework or modification.
- Broad Concrete Pump Compatibility — Verified fitment across the LS and ST-45HRM hydraulic-driven concrete pump families, covering a wide range of jobsite output capacities.
- Maintains Pumping Pressure — A correctly seated sleeve sustains the hydraulic seal that drives consistent material flow; a worn or damaged sleeve can cause pressure loss and uneven output.
- OEM Part Number Traceability — Part number this part matches Multiquip's published service documentation, so technicians can cross-reference the part against their service manual with confidence.
A sleeve in a hydraulic concrete pump serves as a precision-machined liner or housing component within the pumping circuit, providing a controlled bore through which hydraulic or material flow is directed and sealed. It works in conjunction with pistons, seals, and valve assemblies to maintain the tight tolerances needed for consistent pumping pressure and smooth material delivery. When a sleeve wears, scores, or develops surface damage, pressure drop, erratic output, or accelerated seal wear typically follows, making timely replacement essential to keeping the pump operating at rated capacity.
