The Multiquip 458338001 Pump Assembly is a genuine OEM component designed for MVH-series reversible plate compactors, including the MVH-120GH, MVH-150D, MVH150VD2, MVH120VGH, MVH-150D2, and MVH150VGH. As a direct OEM replacement, part 458338001 is built to the same specifications as the original unit, ensuring a drop-in fit without the guesswork of sourcing a cross-referenced substitute. DHS Equipment stocks this part to help you get your reversible plate compactor back in service fast.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to the original pressure and flow specifications required to drive the MVH series reversible plate mechanism, not a generic pump adapted from another application.
- Direct-Fit Replacement — Matches the original mounting configuration and port dimensions on MVH-series compactors, allowing installation without modification to existing hose connections or mounting hardware.
- Broad MVH Series Compatibility — Confirmed fitment for MVH-120GH, MVH-150D, MVH150VD2, MVH120VGH, MVH-150D2, and MVH150VGH reversible plate compactors.
- Sustained Compaction Force — A properly functioning pump assembly maintains consistent hydraulic pressure to the exciter system, preserving the compaction output and plate reversibility the MVH series is built around.
- Verified Part Number — Sourced directly from Multiquip as part number 458338001, eliminating substitution risk when ordering for a specific MVH model.
The pump assembly on an MVH-series reversible plate compactor is responsible for generating and delivering the hydraulic pressure that controls plate direction and exciter operation. Without a functioning pump, the machine loses its ability to reverse travel direction and may suffer a significant drop in compaction force — both of which directly impact productivity on asphalt and granular base applications. A worn or failing pump assembly typically presents as sluggish plate response, inability to reverse, or visible hydraulic fluid loss, and should be replaced promptly to prevent further damage to the hydraulic circuit.
