The Multiquip MQ999743 Liner.023" 10FT 6MM Type is a genuine OEM component designed for the MT400CCEHD concrete pump. Sourced directly through Multiquip's authorized parts network, this liner delivers the exact material specification and dimensional tolerancing required to maintain consistent pump output in the MT400CCEHD. If you're servicing or rebuilding the pump system on your MT400CCEHD, MQ999743 is the correct OEM replacement to spec.
Key Features
- OEM-Grade Material Specification — Manufactured to the exact wall thickness and bore diameter required for consistent concrete flow and controlled wear rates in high-cycle pump operation.
- Correct Length and Diameter — Cut to 10 feet at the 6MM (.023") type spec, this liner drops directly into the MT400CCEHD pumping system without field modification.
- Confirmed MT400CCEHD Fitment — Verified for the MT400CCEHD concrete pump; cross-reference MQ999743 against your machine's parts manual before ordering.
- Maintains Pumping Efficiency — A properly fitted liner keeps material moving at design pressure; a worn or incorrectly sized liner causes sluggish output, blockages, and accelerated wear on surrounding pump components.
- Genuine Multiquip OEM Part — Backed by Multiquip's parts program, ensuring the component meets the same standards as the original production unit.
A pump liner is the wear surface inside the material cylinder of a concrete pump, guiding mixed concrete through the pumping circuit under pressure. Over time, abrasion from aggregate and slurry erodes the liner's inner wall, reducing delivery pressure and increasing the risk of blockages or cylinder damage. Replacing the liner on schedule with a correctly sized unit — such as MQ999743 at the .023" / 6MM type specification — restores full pumping capacity and protects the piston and cylinder from premature wear.
